    According to one aspect of the present invention, there is provided a method of a drilling arrangement comprising a drive means support device for fixing a drive means arranged in the drilling arrangement acting in one direction, the method comprising: - providing a drive head with a rotary shaft intended for engagement with a drill string means; Providing the drive head pivotally about an axis of rotation extending across said direction; pivoting the drive head from a first fixed end position where the axis of rotation of the drive head is parallel to said direction and the drive means drives the drive head in a first direction to a second fixed end position where the axis of rotation of the drive head is parallel to said direction and the drive means drives the drive head in a second direction .
    In this way, a flexible method and space-saving drilling arrangement are achieved.
    In this way, a cost-effective and from a work environment aspect more favorable procedure is also achieved. Advantageously, a drilling rig arranged in a first space for driving a drill bit in a first direction can be flexibly used for driving the drill bit in a second direction. In this case, the setting of the drilling rig (clamping in the locality) can be maintained and said second direction drilled in a direction opposite to the first direction. In another case, the drilling rig can be loosened a bit and turned to the appropriate direction, clamped and the drive head pivoted 180 degrees so that drilling in the second direction can take place in a different direction from the first space, but not necessarily in line with the first direction.
    Preferably, the step includes pivoting the drive head 180 degrees about said axis.
    The definition of said pivot of the drive head about the axis extending transversely to the action movement of the feed means includes that the axis of rotation of the drive head is pivoted from a position where the axis of rotation has an extension parallel to the direction of said action movement.
    Alternatively, all or part of said drill string means is released from the drive head after driving a first borehole.
    Suitably, said drill string means is provided in engagement with said drive head for driving a second borehole.
    Suitably, said boreholes are driven by means of successive feeds in said first and second directions, respectively. Preferably, the first borehole is driven between a first space where the drilling arrangement is positioned and a second space, and the second borehole is driven between the first space and a third space.
    Here, the drilling arrangement can be advantageously used for escape drilling, riser drilling or for other drilling where two holes drilled in line are to be taken up from a first space.
    Preferably, each hole is terminated in each of its second and third spaces, respectively.
    Alternatively, the step of rotating the drive head about the shaft is effected by means of a motor or semi-manually.
    In this way, the procedure can take place by controlling a control unit operated by an operator and a connected computer.
    Preferably, the step of manually rotating the drive head about the shaft is effected.
    Preferably, the step of pivoting the drive head between two lockable end positions is effected.
    Preferably, the respective end position is locked with bolts between the feed means and the drive head.
    Alternatively, these end positions are locked by means of said control unit and locking wedges or similar locking means are controlled to lock the drive head in position.
    These objects are also achieved by means of a drilling arrangement defined in the introduction having the features stated in the characterizing part of claim 6.
    According to one aspect of the present invention, there is provided a drilling arrangement for mining operation comprising a drive means support device for fixing a drive means arranged in the drilling arrangement acting in one direction and a drive head with a rotational shaft intended to engage a drill string means, wherein: the drive head is pivotally arranged for rotation axis of rotation extending transversely to said direction between a first and a second end position, in the first end position the axis of rotation of the drive head is arranged parallel to said direction and the drive means is arranged to drive the drive head in a first direction, in the second end position the axis of rotation of the drive head is arranged parallel to said and the drive means is arranged to drive the drive head in a second direction, and the directions are opposite, the drilling arrangement allowing drilling in the two opposite directions.
    An alternative term for said drilling arrangement is herein rock drilling arrangement.
    Said first end position is a fixable end position. Said first end position is a fixable position. Said first end position may be a lockable position. The term "first end position" thus refers to a "first fixable position" or a "first lockable position".
    Said second end position may be a fixable end position. Said second end position may be a fixable position. Said second end position may be a lockable position. The term "second end position" thus refers to a "second fixable position" or a "second lockable position".
    In this way, a drilling arrangement is provided which can cost-effectively drill two holes in opposite directions from a common space. It is also provided here that the drilling arrangement can be used in small spaces without having to return to larger spaces to turn the drive means support device. The drive means support device may be clamping legs having support plates arranged for bars against the walls of the space.
    The clamping legs are then designed to support the feed means (such as hydraulic cylinders, pneumatic cylinders, etc.). The feed means feeds the drill string means including drill steel and drill bit in the direction of the borehole. Turning a drilling arrangement in such a small space requires a great deal of work and often involves disassembly of the various components.
    Preferably, the drive head is connected to a drive motor via a gearbox, which together form a pivotable unit.
    This provides an integrated unit that is user-friendly to operate.
    Alternatively, a spacer is provided between a feed cylinder and the drive head foundation on either side of the foundation. The spacers each have a pivot pin. The respective spacer is screwed to the housing of the feed cylinder. The pivot pin is in turn fitted into a bearing which is mounted at said foundation. Recesses are suitably provided in the foundation for accommodating stop flanges applied to and retaining said pivots at the respective bearing. 10 15 20 25 6 In this way, during assembly, the foundation can now be easily pushed in between the bearings and screwed on by means of bolted joints.
    Suitably said feed means and drive head are both arranged to be driven by means of pressurized fluid.
    In this way, for example, a vehicle's hydraulics or associated pressure source can be used, whereby large feed force (feeding of drill string back and forth) and drilling force (rotation) can be achieved.
    Alternatively, the pivot means comprises at least one pivot pin rigidly mounted to the feed means and said drive head can be mounted so as to be mounted thereon.
    Here, a drilling arrangement can be user-friendly mounted in a space where first clamping legs and feed cylinders are applied in position after which the drive head (chuck) with or without rotary unit (motor and gearbox) is pivotally mounted on suitably two pins each mounted on a feed cylinder.
    Preferably, said first and second direction actuating means comprise at least two double-acting cylinders between which the drive head is releasably attached and is pivotable between two lockable end positions.
    According to one aspect of the invention, the drilling arrangement has a flexible and robust design which is also reliable and easy to use. According to such an aspect, slight mechanical adjustments are needed to position the drilling arrangement in position to drill a second hole in the opposite direction of a first hole, which position is common to both holes.
    In the drilling arrangement, the drive head can thus be pivotable relative to the drive means support device and drive means (feed cylinders) in order to easily drill a second opposite hole. Thus, according to one aspect of the invention, only a fairly simple programming of the control unit is required to control the operation of the drilling arrangement. Such a control unit positions the drilling arrangement, provides that the clamping legs are clamped against the walls of the space, provides pivoting of the drive head to the selected position, control and control of feed pressure both in terms of feeding the drill string in the direction of the borehole and rotation of the drill string. The above objects are also achieved with a vehicle comprising the drilling arrangement, which vehicle may be a motor vehicle. The vehicle can be a drilling rig intended for mining.
    According to one aspect of the invention, there is provided a computer program for positioning the drilling arrangement, said computer program comprising a program code stored on a computer readable medium for performing the method steps of any of claims 1 to 5 when the computer program is executed by said electronic controller associated with bo. rra rra ngemanget.

    DETAILED DESCRIPTION OF THE FIGURES Details which are not of major importance to the inventive concept are omitted from the drawing for the purpose of clarifying the figures.
    Referring to Figure 1, a mining machine 1 is shown. According to one embodiment, the exemplified vehicle 1 is a so-called mining machine 3 adapted for mining operation. The vehicle 1 is a motor vehicle with four wheels 5 and is provided with a drilling arrangement 7 with the possibility of accommodating two riser holes at one and the same positioning of the drilling arrangement 7. The drilling arrangement 7 is shown in Figure 1 in transport position for transport to the drilling heel position (not shown ) from a first space 9, e.g. a tunnel or a mine. The drilling can be done up or down. The drilling can also be done to the sides. The drilling can take place in any direction in any direction. The drilling rig 3 shown in Figure 1 is flexible and space-saving.
    Figure 2 illustrates the vehicle 1 in Figure 1 when positioning the drilling arrangement 7 in the first space 9. The drilling arrangement 7 is placed in position between two wall sections 8 of the space 9, wherein the extent of the drilling arrangement 7 is oriented in the direction of the borehole to be drilled.
    According to this embodiment, the vehicle 1 is operator-controlled by an operator (not shown) by means of a first control unit 100. A communication link between the drilling arrangement 7 and the control unit 100 is indicated by reference numeral L100. A second control unit 110 is arranged for communication with the first control unit 100 and is an external control unit and is used to load software to the first control unit 100 via the link L110 which is part of an internal network in the vehicle 1.
    The operator maneuvers four support legs 11 (only two are shown) (of a drive means support device) to take struts against said wall section 8. A drive means 13 (feed means 14) in the form of two double-acting hydraulic cylinders 15 is connected to the support legs 11. Between the hydraulic cylinders 15 is a motor unit 17 (shown in more detail in Figure 3) comprising gearbox, drive head and chuck (not shown), pivotally mounted. The operator operates the motor unit 17 to pivot to a first end position, in which a chuck (not shown) of the motor unit 17 faces the position of the first borehole to be drilled, and the control unit 100 ensures locking of the motor unit 17. A first drill steel (not shown) is fitted engaging the chuck with one end and its other end a drill bit (not shown). Mounting of drill steel is done by the operator via the control unit 100. The control unit 100 then provides, under the supervision of the operator, drive of the drill bit and continuously controls hydraulic pressure both in terms of pressure applied to hydraulic cylinders 15 and pressure driving rotation of the motor unit 17 for rotation of the drill steel with drill bit.
    The control unit thus controls the operation of the drilling arrangement by means of control signals via the link L100.
    A second drill steel is connected to the first drill steel and subsequent drill steel is switched on as the drill bit works its way into the rock.
    When the drive of the first borehole is complete, the drill steel is released from the chuck. The support legs 11 are released and the feed member 14 is pivoted 180 degrees about an axis of rotation or axis of rotation (Ai Fig. 4a) which extends across the direction R in Fig. 8b for the action of the hydraulic cylinders 15 and / or across the extension of the hydraulic cylinders 15 to a second position. The definition of said pivoting of the drive head about the axis extending transversely to the action movement of the feed means involves rotating the drive shaft of the drive head (see reference 22 in Fig. 3 and Fig. 8b) between two end positions where the axis 22 of the rotation axis is parallel to the direction of said two movements. .
    The operator thus operates the motor unit 17 to pivot to a second end position, in which the chuck faces the position of a second borehole to be drilled, and the control unit 100 ensures locking of the motor unit 17 in this end position. The first drill steel and the drill bit are again applied to the chuck, in which again the mounting of the drill steel takes place through the operator's supply via the control unit 100. The control unit 100 then provides, under the supervision of the operator, drive of the drill bit to receive the second hole. The control unit 100 simultaneously controls hydraulic pressure for hydraulic cylinders 15 and engine unit 17.
    Figure 3 illustrates the motor unit 17 having drive heads 19. The loror unit 17 according to this embodiment is an integrated unit for rotation of drill steel and drill bit and escape head (not shown). The motor unit 17 comprises a gearbox 21 which in turn is in driving connection with the chuck. The motor unit 17 is arranged for signal connection with the control unit (not shown). The axis of rotation 22 of the drive head 19 is the axis about which the drive head in operation rotates the drill string (drill steel and drill bit / reamer).
    Figure 4a illustrates an embodiment of the drilling arrangement 7 comprising a drive head 19, arranged for co-operation with two hydraulic cylinders 15 'which are arranged to operate in a first and second direction R, respectively. The direction R corresponds (is parallel to) the direction 22 for drilling direction closest to the drilling arrangement 7. The drive head 19 is pivotally mounted between the pneumatic cylinders 15 about an axis of rotation or rotation A extending transversely to said direction R. The shaft A in turn extends through two pins 23, each rigidly mounted on the respective pneumatic cylinder 15 '. Corresponding recesses 24 of flanges 25 formed at the drive head 19 receive said pins. The drive head 19 can be pivoted 180 degrees between a first end position 26 and a second end position 28. In said first end position, drilling takes place downwards (see, for example, Fig. 1). At said second end position, drilling takes place upwards (see eg Fig. 1).
    The drive head is locked in Figure 4a in the second end position 28. Bolts 27 have been screwed into the associated holes of the drive head 19 and thus lock the drive head 19 at the feed means or drive means 13 in the form of the pneumatic cylinders 15 '.
    Figure 4b illustrates an example of pivot joint 29 in which the bearing is provided by means of ball bearings 31 sealed with a respective plate 33. For manual fitting of the drive head 19 between feed cylinders (not shown), shims 35 are mounted at the bearing.
    Figure 4c illustrates an example of pivot joint 29 in which the pin 23 itself is attached to a housing 35 of a drive head 19. This pivot joint 29 is also designed as a swivel coupling in which hydraulic pressure, intended for a hydraulic motor (not shown) for rotating drill steel, can be transferred from a pressure source (not shown) via feed means 13 'without the need for hydraulic hoses. Figure 4d illustrates an example of pivot joint 29 where two pivot means 37 arranged between the drive head 19 and the feed means 14, in the form of a hydraulic cylinder 15, allow the drive head 19 to pivot about a pivot axis A extending transversely to the direction of movement of the feed means 14. An intermediate piece 39, which has the pivot pin 23, is screwed during mounting to said feed cylinder 15. The pivot pin 23 is in turn fitted into a bearing 41 which is mounted on a foundation 43 supporting the drive head 19. Recesses 45 of the foundation 43 are arranged to accommodate stop flanges 47 retaining said pivots 23 at the respective bearing 41. In this way, when mounting, the foundation 43 can now be easily pushed in between the bearings 41 and screwed on by means of bolted joints. This means simple service of the drilling arrangement 7 because the cylinders 15 of the feed member can remain in their positions in cases where the foundation 43 of the drive head 19 is to be mounted or dismounted.
    Figures 5a to 5c illustrate a drive means support device 49 for supporting drive means 13 comprising drive heads 19 according to a further aspect of the invention. Figure 5a shows that the drive means support device 49 is formed as a rigid frame 51 which is anchored with strong bolts in a rock tunnel floor of a first space 9 '. The frame 51 supports the drive means 13 formed as a feed unit 13 "formed by means of a rack 53 and drive wheels 55. At the feed unit 13" a drive head 19 having an electric drive motor 57 is pivotally and releasably mounted. A drill string 59 with drill steel and drill bit 61 has been threaded to the drive head 19. and the feed unit 13 "is driven in the direction of the arrow P by means of an electric motor actuating the drive wheel 55 in engagement with the rack 53. In this way, the drill string 59 with the drill bit 61 drives a pilot hole until a second space is reached 9". Figure 5b shows that the drill bit 61, when free in the second space 9 ", is replaced by a reaming head 63, after which the feed unit 13" pulls the drill string 59 in the direction back towards the first space 9 'while the electric drive motor 57 rotates the reaming head. Figure 5c shows that after the reaming head 63 has been driven to the first space 9 ', the drive head 19 pivots approximately 180 degrees, drill steel is reassembled and drill bit 61. The feed unit 13 "now feeds the rotating drill bit 61 in direction P' towards arrow P '. a third space 9 "'where the drill bit 61 will be replaced with an escape head 63 for escaping a second hole back to the first space 9'. Figures 15a to 6b illustrate a drilling arrangement 7 according to a further embodiment of the invention. According to this embodiment, the drilling arrangement 7 is arranged in a tunnel for driving a first hole first in a first direction and then for driving a second hole in a second direction, which method is also shown with a flow chart shown in Figure 9b. A remotely controlled motor vehicle 1 has been operated to set selected parts of the drilling arrangement 7 in position so that a few meters deep holes can be drilled from the tunnel in the radial direction. The motor vehicle 1 is remotely controlled to position the drilling arrangement 7 in selected positions along the extent of the tunnel. The vehicle 1 is then remotely controlled to carry out the drilling arrangement 7 and the radial holes are fitted with explosives for blasting and widening the tunnel.
    Figure 7 illustrates a drilling arrangement 7 according to a further embodiment, wherein the drilling arrangement 7 is positioned for drilling two almost horizontal holes 65. To facilitate pivoting of the drive head 19 in narrow spaces, drive motor 57 'is applied for rotation of drill string 59 in the vicinity of the first space 9'. tunnel wall 10. Hydraulics (not shown) actuate via a drill string attachment the drill string 59 for feeding in opposite directions, i.e. back and forth, driving a drill bit 61.
    Figures 8a-8c illustrate a pivoting mechanism 69 according to one embodiment. Figure 8a shows a drive head 19 in a first end position V1. A semicircular backdrop (disc with semicircular curvature having grooves for wires) 71 is rigidly mounted on the drive head 19. Storage is provided by means of sliding bearings (not shown) arranged at the axis of the backdrop. A traction cable 73 is applied with one end coupled to a distal portion of the link 71 and partially overlying the link 71. When the drive head 19 is to be rotated 180 degrees, the lock is disengaged in the end position and the drive head 19 assumes the position shown in Figure 8b. The traction cable 73 is clamped by means of a traction yoke 75 rigidly attached to a casing surface of a feed cylinder 15 which can act as a feed even when drilling. The feed cylinder 15 is then used as an aid to pivot the drive head 19 to its second end position for locking. The second end position V2 is shown in Figure 8c.
    Figure 9a shows a flow chart according to an aspect of the invention. The first step 200 involves starting. Step two 202 includes positioning the drilling arrangement 7. Next, a third step 203 is provided to fix drilling support or a drive means support device 49 for supporting a drive means 13 associated with the drilling arrangement. Thereafter, a locking 204 of a drive head 19 of the motor unit 17 is provided. in a first end position. The reading takes place against a feeding means 14, such as hydraulics or other double-acting feeders. The drive head 19 is arranged for co-operation with the feeding means 14 acting in a first and second direction, respectively.
    Thereafter, a first pilot heel is driven with pressure 205 by providing drill string means (such as drill stand, drill bit 61, etc.) in engagement with said drive head 19 for driving the first drill heel. Thereafter, an escape 206 is provided in the opposite direction by the feeding means acting in the opposite direction. Then, when the drive of the first drill heel is complete, the drill string 59 is released from the drive head 19 and the drive head is pivoted 207 180 degrees about an axis extending transverse to the direction of action of the feed member 14 and read.
    Thereafter, a second pilot heel is driven by pressure 208 by providing drill string means (such as drill string, drill bit 61, etc.) in engagement with said drive head 19 for driving the second drill heel. Thereafter, the pilot heel 209 is accommodated by feeding in the opposite direction. Thereafter, the drill support 210 is released so that the drive member 13 can be moved in the first space. Then regroup or end 211 is selected. If regrouping is selected, the procedure restarts with step two and the procedure is repeated.
    Of course, according to another aspect of the invention, the drive member support device 49 may be detached (the support legs 11) and the entire drilling equipment (including the drive member support device 49, i.e. the drill arrangement 7 of the drilling arrangement 7) adjusted a bit in the location and directed to drill a second hole in a second direction. does not correspond to the opposite direction but can correspond to any direction. For example, the drilling rig could be rotated (seen in the extension of the locality) 10 degrees and still be tensioned against the rock so that the operator then rotates the drive head around the pivot axis A 180 degrees. In this way a flexible drilling arrangement 7 has been provided.
    Figure 9b shows a flow chart according to an aspect of the invention. The first step involves starting 300. Step two 302 comprises positioning the drilling arrangement 7. Next, a third step 303 is included to fix drilling support or a drive means support device 49 for supporting a drive means 13 associated with the drilling arrangement 7. Thereafter a reading of a drive head 19 of the motor unit is provided. 17 in a first end position 304. The reading takes place against a feed means 14, such as hydraulics 15 "or other double-acting feeders. Thereafter, a first heel is driven by feed pressure on a rotating drill bit. Then, when the drive of the first drill heel is complete, the drill bit 61 is fed back into direction of the drive head, the drill string is disengaged from the drive head 19 and the drive head 19 is pivoted 180 degrees to a second end position 306 about an axis extending transversely to the direction of action of the feed member 14 and locked, then a second hole is driven. drilled and drill string and drill bit disconnected, loosen the drill support 308 and drill the arrangement 7 is transported away.
    Figure 9c illustrates an aspect of the invention. The process begins with start 401. Drive means 13 having hydraulics 15 "and drive head 19 are provided. The hydraulics 15" cooperate with the drive head 19 to rotate the drill bit 61 and drive it in the direction from or to the drill arrangement 7. In a step 402 between bores in two opposite directions the drive head turns 19 180 degrees. The last step 403 is to finish. The step 402 thus comprises providing a drive means support device 49 for supporting a drive means 13 arranged at the drilling arrangement 7, providing said drive means 13 with a drive head 19 arranged for co-operation with a feed means 14 acting in a first and second direction P, P ', respectively, to provide drill string means 59 in engagement with said drive head 19, to pivot the drive head 19 about an axis A extending transversely to the direction of action of the feed member 14.
    The definition of said pivoting of the drive head 19 about the axis A extending transversely to the action of the feed means includes that the axis of rotation of the drive head is pivoted between two end positions where the extent of the axis of rotation is parallel to the direction of said movement of action in both end positions.
    Figure 10 illustrates a control unit 100 according to an embodiment of the invention. Herein, a diagram of an embodiment of a device 500 is shown. The control units 100 and 110 described with reference to Figure 2 comprise according to this embodiment said device 500.
    The device 500 includes a non-volatile memory 501, a data processing unit 502 and a read / write memory 503. The non-volatile memory has a first memory portion 504, in which a computer program P, such as an operating system, is stored to control the operation of device 500. Further, device 500 includes a bus controller, a serial communication port, I / O means, an A / D converter, a time and date input and transfer unit, an event counter and an interrupt controller (not shown). The non-volatile memory 501 also has a second memory portion 505.

    While the invention is so defined by the following claims, it should be pointed out that the invention is not limited to the features stated therein, but further embodiments and combinations of described embodiments are possible. For example, the drilling arrangement per se may comprise a remote controlled vehicle transporting the equipment to the intended location. The vehicle can be set up for autonomous steering. For example, a communication link may be a physical line, such as an optoelectric communication line, or a non-physical line, such as a wireless connection, for example a radio or microwave link. Swivel of the drive head can take place around 180 degrees and is considered with regard to the force vector of the drilling arrangement or drilling angle or application for drilling. The rotation of the drive head can take place completely automatically. The drilling can be attributed to riser drilling or other escape drilling where one seeks to connect a space with two other spaces and the spaces are located in a plane, horizontally, vertically or in between. Today, a technique is used to drill tunnels called ridge drilling. Ladder drilling is often used to drive boreholes, such as shafts and / or risers between a first, second and third space. Thus, in the case of drilling rig drilling, spaces in different levels or horizontally lying spaces in a mine can be connected for communication, in which ventilation, material transport or elevator can be arranged. Usually a pilot hole is first drilled in a first direction from the drilling arrangement. The often strong feed pressure required can be achieved by clamping a drilling arrangement belonging to the drilling rig by means of, for example, clamping legs, which press support grippers against the walls of the first space.
    For example, a drilling arrangement can be arranged for so-called riser drilling where driving (the drive means feeds a rotating drive head or chuck with compressive force) takes place in a first step by means of a drill bit for drilling pilot holes and then the drive is reversed (the drive means feeds the rotating drive head or chuck with traction) in a second step by means of an escape head in the opposite direction. By using this in-situ established push and pull function of the drill tower where you only need to turn the drive head for new drive of the drill in the opposite direction (or after appropriate adjustment of the drill tower, in some other direction), you need do not turn over the entire drilling arrangement, which is otherwise time consuming.
    Double-acting hydraulic cylinders are operated to push a rotating drive head (including a chuck) in the first direction affecting a drill string comprising a drill bit disposed at its outermost end. This creates a feed force (pressure) which presses the drill bit in said first direction. When the drill bit has reached its target and is free in the second space, the drill bit is replaced with a reaming head, after which the drill string is pulled in the opposite direction by means of the double-acting hydraulic cylinders and a traction is transferred to the reamer head which holds the hole to final diameter. The drill string can have sections with drill steel, drill rods, drill pipes, etc., which sections are built on or removed gradually based on the feed direction.
    The definition of the direction of action of the feed member 14 is the direction of movement in which, for example, hydraulic cylinders drive / feed the drive head of the drilling arrangement for drilling boreholes. The action of the feed member takes place in a direction substantially parallel to the axis of rotation of the drive head.
    The definition of pivoting the drive head about an axis of rotation or rotation extending across the direction in which the feed means acts, or feeds the drive head, means that the drive head is pivoted from a first to a second end position. These two end positions are provided that when the drive head is locked in these end positions, the axis of rotation of the drive head will extend parallel to (or at least substantially with) said direction in which the feeding means acts.
    Alternatively, the drilling arrangement according to an aspect of the invention may be remotely controlled, whereby an operator at a distance from the drilling arrangement, for example from the ground surface, may control the method of pivoting the drive head. According to another alternative, the drilling arrangement can be a remotely controlled vehicle arranged with the drilling arrangement, wherein an operator remotely controls the vehicle to the intended place for drilling, drills and then back. According to another alternative, the drilling arrangement comprising a carrier can be of an autonomous nature, whereby an operator only needs to start the procedure and the process proceeds by itself to completion.
