    TECHNICAL FIELD The present invention relates to a method for drilling rig generation. The invention also relates to a computer program product comprising program code for a computer for implementing a method according to the invention. The invention also relates to a system and a drilling rig equipped with the system.
    BACKGROUND Today, electronic drilling plans are used in, for example, the mining industry. These drilling plans are used as instructions and aids for sectionally drilling a number of holes in the body to be blasted and emptied of material. Said drilling plans include information on, for example, where start and end points are positioned and what diameter each such drilling rig must have. In this case, the points of application for boreholes are specified, as well as the direction, length and diameter of each borehole. This also shows the distribution in the board body that the boreholes must show. An operator of a drilling rig can use a sequence of different predetermined drilling plans to successively drill a number of predefined holes following blasting, whereby a desired tunnel or location can be created in, for example, a rock or mine.
    Said electronic drilling plans are today produced in advance at, for example, a planning office, whereby said drilling plans are saved on a portable memory and taken by the operator to the drilling rig to be used for drilling. The electronic drilling plans are then loaded into a computer arranged on the drilling rig for use in operating the drilling rig.
    A drilling plan can be presented in two or three dimensions on a display screen of the board computer. The drilling plan can comprise a number of different areas, which can be presented as a surface in two dimensions or a volume in three dimensions. Such an area is called wedge. A number of adjacent areas are specified in addition. Other areas in the drilling plan are called struts. A common set of struts of a drilling plane defines a left and right struts, which are located to the left and right of said wedge, respectively. Furthermore, an area located adjacent above said left ridge, wedge and right ridge is usually called the upper ridge. Similarly, an area under the said left strut, wedge and right strut is usually called the lower strut. The said four areas can be surrounded by a so-called inner contour and an outer contour. Said outer contour defines an outer boundary starting points for boreholes. A part of said outer contour can be called a bottom row, constituting a downward delimitation, ie the corresponding surface.
    After boreholes have been drilled in accordance with a provided drilling plan, these blasting agents are filled, whereby suitable blasting is performed. Typically, a section is blasted in a sequence respect to said areas and contours, where said wedge is blasted first, after which side struts, upper wedge and lower wedge are blasted. Said inner and outer contours are blasted in a suitable manner.
    These drilling plans are today manufactured manually, which is relatively time-consuming. For several reasons, this is not an optimal procedure. For example, knitting can be arbitrarily adapted to a single contour. When operating a drilling rig, several corrections of the orientation of drilling devices of the drilling rig for correct alignment before drilling different holes may be required, which is both cumbersome and time consuming. Delays caused by board corrections are associated with high costs. Furthermore, the said necessary corrections are associated with extra manual work for an operator and can in this case cause stress and perceived heavier workload.
    SUMMARY OF THE INVENTION There is thus a need to reliably and user-friendlyly generate improved drilling plans for a drilling rig. There is a need here to enable the generation of drilling plans for a drilling rig in a time-efficient and user-friendly manner.
    An object of the present invention is to provide a new and advantageous method for drilling rig generation.
    Another object of the invention is to provide a new and advantageous drilling rig generation system and a new and advantageous drilling rig generation computer program.
    A further object of the invention is to provide an alternative drilling rig generation method, an alternative drilling rig generation system and an alternative drilling rig generation computer program.
    A further object of the invention is to provide a method, a system and a computer program for improved drilling plan generation where a need for corrections of the orientation of drilling devices is minimized.
    A further object of the invention is to provide a method, a system and a computer program for drilling rig generation in order to achieve a more time-efficient, and thereby cost-effective, operation of a drilling rig.
    Some of said objects are achieved with a drilling rig generation method according to claim 1. Other objects are achieved with a drilling rig generation system according to claim 12. Advantageous embodiments are stated in the dependent claims.
    According to one aspect of the present invention there is provided a drilling plan generation method wherein a drilling plan specifies a plurality of boreholes having a start point and end point, which boreholes are distributed within areas defined in the drilling plan, which areas include a first area and at least a second area adjacent said first area, comprising the step of: specify the boreholes of the drilling rig based on a desired hole distribution with respect to each borehole endpoint and an effort to maximize the number of boreholes in said at least one second area which are mutually parallel and thereby caused to run in a reference direction of the drilling rig.
    Said method can advantageously be performed automatically by means of a computer. In this case, a large number of parallel holes in the drilling plane can be generated, whereby a more time-efficient drilling method is achieved. By maximizing the number of parallel holes, the time required to change the orientation of drilling devices of the drilling rig can be minimized. In this respect, a component-sparing drilling method is also provided, since exemplary hydraulics for controlling arm-supporting drilling devices do not need to be used to the same extent as before. With the inventive generation of drilling plans, user-friendly and time-efficient parallel movement of the drilling rig's arms supporting drilling devices can be achieved. By automatically generating drilling plans for a drilling rig, it enables an advantageous adaptation to the exact shape and size of the tunnel that applies to the current position. The inventive method including automatic generation of boreholes thereby provides boreholes where the number of mutually parallel boreholes can be maximized. The method may comprise one of the following steps: - determining said reference direction as a direction of boreholes in said first region, which first region is a wedge; determining said reference direction as a direction of boreholes in an upper part of a contour of said drilling plane; determining said reference direction as a direction of boreholes of a bottom row of said drilling plane; and determining said reference direction on the basis of certain rules.
    This provides a versatile and flexible method according to one aspect of the present invention. By determining the tribunal reference direction in a simple and user-friendly manner and generating said drilling plan taking into account the determinant reference direction, a large number of parallel holes can be specified, which advantageously streamlines the drilling procedure.
    Said rules may be predetermined rules comprising specifying how boreholes within said first area are distributed with respect to hole spacing and row spacing. The method may comprise the steps of: - determining a desired distance between borehole endpoints of the boreholes in said at least a second region; - distributing said borehole endpoints of the boreholes in said at least one second area according to said determined desired distance; and distributing borehole start points of the boreholes in said at least one second region at the base of said distributed borehole endpoints. Said borehole starting points of the boreholes in at least a second area can also be distributed in accordance with said effort to maximize the number of boreholes in said at least a second area which are mutually parallel and thereby run in said reference direction of the borehole. The method may comprise the step of: boreholes in said at least one second area by single densification or glazing for an adaptation to borehole endpoints distributed based on said desired distance between borehole endpoints, such boreholes not belonging to said mutually parallel boreholes.
    By adjusting the position of said borehole starting points of the borehole plan corresponding to borehole endpoints according to the inventive method, the number of boreholes that do not belong to a set of mutually parallel boreholes can be minimized. The method may include the step of: - taking into account rules for maximum and / or minimum said borehole starting points of boreholes of said borehole plane.
    By distributing borehole starting points of boreholes in a starting plane taking into account these rules regarding maximum and / or minimum allowable distances between said borehole starting points in boreholes of said borehole, said distribution can be adapted to prevailing conditions, including for example composition of the drill body, drilling rig performance and associated diameter different boreholes.
    Said maximum permissible distance between borehole starting points of boreholes of said borehole plane may be a predetermined value. This maximum permissible value can be determined on the basis of, for example, the diameter of adjacent boreholes in the drilling plane. It is advantageous to avoid specifying said boreholes too sparsely placed. In this case, it is advantageous to avoid not obtaining excessive blocks of drill body material during blasting.
    Said minimum allowable distance between borehole starting points of boreholes of said borehole plane may be a predetermined value. This minimum permissible value can be determined on the basis of, for example, the diameter of adjacent boreholes in the drilling plan. It is advantageous to avoid specifying said boreholes too closely placed. The method may comprise the step of: - determining whether the number of boreholes in said borehole plane is to be increased or decreased for adapting rules concerning maximum and / or minimum permissible distances between said borehole starting points and / or borehole end points of boreholes. .
    This provides a flexible and adaptable drilling rig generation method where boreholes can be easily added or removed to maximize the number of parallel boreholes in the drilling rig. The method may include the steps of: - specifying said existing drilling rig in such a way that it said first area and four further areas including an area on each side of said first area and an upper area, located above said first area and the areas on each side of said first area, and a lower area located below said first area and the areas on each side of said first area; and -in said existing drilling plane, specifying said areas within the framework of an outer contour.
    A drilling plan is hereby provided which is extremely practically applicable for sequential and efficient blasting. The method may comprise the steps of: - determining a desired distance between vertical rows of borehole end points of the boreholes in said at least one second area; distributing said vertical rows of borehole endpoints of the boreholes in said at least one second region according to said determined desired distances; and distributing vertical rows of borehole starting points of the boreholes in said at least a second area accordingly.
    In this case, an optimal distribution of vertical rows of a side strut of the drilling plan can be provided. This means that boreholes distributed on said vertical rows can to a large extent be specified as mutually parallel running.
    Said vertical rows of borehole starting points of the boreholes in said at least one second area can also be distributed in accordance with said effort to maximize number of boreholes in said at least one second area which are mutually parallel and thereby run in said reference direction of the borehole plan. distributing said vertical rows of borehole starting points of boreholes in said at least one second area by a densification or misalignment for an adaptation to said vertical rows of borehole endpoints distributed based on said desired distance intermediate rows of borehole endpoints, such vertical rows being grouped by lines. In this case, an optimal distribution of vertical rows of a side strut of the drilling plane can be provided.
    By adapting the position of said vertical rows of borehole starting points in the drilling plan to the corresponding vertical rows of borehole endpoints according to the inventive method, the number of boreholes which are mutually parallel boreholes can be maximized. The method may include the step of: - taking into account between said vertical rows of borehole starting points of boreholes of said borehole plane.
    By distributing vertical rows of borehole starting points in a starting plane taking into account these rules regarding maximum and / or minimum permissible distances between said vertical rows of borehole starting points of said drilling plane, said distribution can be adapted to prevailing conditions, including for example composition of the drill body and drilling rig performance. diameter of the various boreholes.
    Said maximum permissible distance between vertical rows of borehole starting points of said drilling plane may be a predetermined value. This maximum permissible value can be determined on the basis of, for example, the diameter of adjacent boreholes in the drilling plane. Advantageous in that the rows are placed too sparsely. In this case, it is advantageous to avoid not obtaining excessive blocks of drill body material during blasting.
    Said minimum permissible distance between vertical rows of borehole starting points of said drilling plane may be a predetermined value. This minimum permissible value can be determined on the basis of, for example, the diameter of adjacent boreholes in the drilling plan. Advantageous in that the rows are placed too tightly. In this case, it is advantageously avoided that drilled holes go inwards.
    The method may comprise the step of: - directing boreholes with a borehole starting point at a contour of the drilling plan so that the borehole projection is in a normal direction to said contour. This is mainly applicable and advantageous where the roof and walls of the tunnel are straight. An advantage of straightening boreholes according to the inventive method of a curved contour is mainly advantageous when a front contour (at hole start) and a rear contour (at hole end) are different sizes. In this case, boreholes are provided in said drilling planes which are practically possible to drill.

    Figure 3a schematically illustrates an example of an electronic drilling plane PBP. Board drilling plan PBP is in this case an existing drilling plan which has been manufactured in accordance with the method according to the invention. Said drilling plane PBP can be manufactured at a planning center located remote from the drilling site with said drilling rig 100. Said drilling plane PBP can be supplied to said first control unit 200 in a suitable manner, for example by means of a portable memory or via link communication, such as a wireless link or a physical line. Alternatively, said drilling plane PBP can be produced at the drilling rig 100, for example at the place where drilling is to be performed.
    A drilling plan is a model of how a number of holes are to be drilled in a segment of, for example, a tunnel. A segment can, for example, be 5 meters, and in this case corresponds to a length of the body which it is desirable to first drill and then blow up and then empty of material.
    The illustrated drilling plan PBP is shown in a view in the advancing main direction of an imaginary tunnel. The PBP drilling plan is shown in a vertical view (including a local 2D projection). A drilling plan illustrates entry points for a number of boreholes and how each such borehole should be 18. An entry point is marked in the drilling plan as a circle. Furthermore, an end point is illustrated by a projection of boreholes running from said starting point. Such a projection of a borehole is illustrated as a line starting from said circle with respect to the entry position of a borehole. In this case, a direction and end point for a given borehole can be read from said drilling plane. For a case where a borehole runs orthogonally to said vertical plane, ie straight into the body, said projection of such a borehole in the borehole does not appear in any other way than that only the entry point (circle) is shown.
    The existing drilling plan PBP has a first area W, a so-called wedge. Said first area W has a number of boreholes to be drilled. In this case, said first area comprises five boreholes. Respective projection of the boreholes shows that all boreholes, the first area being directed slightly obliquely upwards at a certain angle. According to one embodiment, the direction of the boreholes in said first area constitutes a reference direction, which reference direction constitutes the direction that the largest possible number of boreholes in the drilling plan must show given that the drilling plan meets certain criteria, such as a predetermined segment of the tunnel.
    It is described here that the drilling plan has at least one second area. Here, four such areas are presented, as below.
    The drilling plan PBP comprises a left strut LS. Said left strut LS has four boreholes, two of which are to be drilled obliquely upwards and two are to be drilled obliquely upwards to the left. In this case, two holes run parallel to said direction of boreholes in said first area W. The two second boreholes have been adapted to borehole end points in an end plane in accordance with the method according to the invention.
    The drilling plan includes a right ridge RS. Said right stross RS has four boreholes, two of which are to be drilled obliquely upwards and two are to be drilled obliquely upwards to the right. In this case, two holes run parallel to said direction of boreholes in said first region W. The two second boreholes have been adapted to borehole end points in an end plane in accordance with an aspect of the method according to the invention. According to this exemplary embodiment, said left lane LS and said right lane RS have substantially the same height as that of said first area W. Alternatively, said left lane LS and said right lane RS may have mutually different shapes which also differ from said first area W.
    The drilling rig includes an upper strut US. Said upper strut US comprises a number of boreholes, a majority of which run in a direction parallel to said direction of boreholes in said first region W. Other boreholes in the upper strut have a direction which adapts to borehole end points in an end plane according to an aspect of the inventive procedure.
