    A method of feeding cement into a drill hole for cement bolting of a rock, according to which a feeder pipe (2) is pushed into the hole essentially to the bottom of the hole portion to be filled with cement, cement is fed into the hole beginning from the bottom of the hole portion, and the pipe is displaced outwards in the hole when the cement fills the hole. The feeding of cement is stopped and the pipe is removed when the amount of cement is sufficient to fill the gap between the wall of the hole and the rock bolt to be pushed into the hole. The displacement of the pipe is controlled by means of the filling pressure (TP) caused by the cement fed between the pipe tip and the bottom of the hole portion to ensure that the hole is reliably filled despite possible cracks and crushed zones. An apparatus for carrying out the method comprises a feeder pipe provided with a tip of such a size that the penetration of cement through the gap between the hole and the tip requires a pressure which is higher than a predetermined set value of the cement feed pressure and causes an outwards pushing force on the tip.

    The invention relates to the field of mining and can be used to mount rocks in the mine workings.

    a second and third feed device control circuit for cement material, respectively; on 12-18 - various stages of work production by the proposed device.
    The device consists of a drilling mechanism 1, a rod feeding mechanism 2, a rod cassette 3 and a feed mechanism 4 for a cement material.
    The feed mechanism 4 has a feeder pipe 5, an actuator 6 and a support device 7, the reader pipe 5 contains a rigid pipe 8. A nozzle 9 is attached to one end of the pipe, and a flexible sleeve to the other end. The free end of the sleeve is provided with a connector 10, during which the sleeve is connected to the pump I1 to terminate the cement material into the feeder pipe.
    The diameter of the feeder pipe is so related to the diameter of the borehole that the penetration of cement material into the gap between the feeder pipe and the rock requires a greater pressure than the supply pressure of the cement material. Consequently, through the continuous supply of cement material into the borehole, the cutter pipe is subjected to a force that is proportional to the feed pressure and pushes the pipe out of the well when the space between the bottom of the well at the filling site with cement material and the feeder pipe is completely filled with cement material, v It is possible to use a flexible hose instead of a rigid pipe 5 at the front end of the pipe feeder. The end of the sleeve can be equipped with a separate feeding nozzle, which can be replaced when worn. When using a flexible hose, the feed nozzle directs the hose when it is inserted into the well.
    The actuator 6 has two frame parts 12 and 13, which are flexibly fastened to one another by bolts 14. Two rollers 15 and 16, respectively, having parallel axes, spaced apart from one another, are rotatably mounted on each ramp of the part. The rollers are mounted opposite one another and provided with a peripheral groove so that each roller pair forms a drive gap between the rollers.

    17 for pipe 3. The drive gap is of such size that the rollers are pressed against the pipe from opposite sides.
    The rollers 16, mounted in the lower frame part, are equipped with sprockets 18 supporting the chain 19. The chain runs around a double sprocket 20 mounted on the lower frame part,
    which maintains the drive chain 21 driven by the motor 22. Therefore, the motor rotates the rollers 16 in the lower frame part with the help of the chain.
    5 The actuator 6 is supported by the frame 23 of the rod mounting device.
    The support device 7 comprises a support beam 24 attached in parallel to the frame 23 of the device for rod mounting, the U-shaped guide links 25 are fixed at a distance from one another on that side of the support beam that faces the frame 23. Guides are of such size that the feeder tube can slide through the guides. The support beam is supported against the actuator 6 so that the guides are coaxial with the drive gap 17 of the actuator 6. The distance between the guides is chosen so that when using the flexible hose as the feeder tube, the sleeve can withstand the force feed without warping. When using a rigid pipe as a pipe, the feeder of one guideline is sufficient at least at a distance controlled by the support device when the connection is established at the front end of the support beam.
    Due to the described construction, the feeder pipe 5 is movable relative to the support beam along the guide links when the rollers 16 of the actuator are rotated by means of a motor. The feeder tube can thus be pushed mechanically.
    0 into the borehole to supply the cement material and to be extracted out of the well during the supply of the cement material.
    When the valve lever 26 control
    5 for the actuator 6 is pushed forward, the pressurized oil flows into the hydraulic motor 22 of the actuator 6, which

    begins to rotate the rollers 16 using chains so that the rollers push the pipe 5 of the feeder into the well. When the feeder pipe reaches the bottom of the well, the control valve returns to its initial position so that the motor stops.
    When the control valve 27 is actuated for the cement material feed pump 11, the pressurized oil flows to the hydraulic motor 28, which rotates the pump so that it begins to force the cement material into the feeder pipe 5. The oil circuit under pressure of the motor 28 is connected through a flow control valve 29, a pressure reducing valve 30 and a two-stable distribution valve 31 to the hydraulic motor 22 of the actuator b. Valve 30 provides fluid flow through the valve until the pressure of the fluid in the motor 22 increases to the extent that the actuator 6 does not move the feeder pipe out of the well through the valve, only this amount of fluid flows through the valve that pressure remains at the same value.
    When cement material is injected into a borehole under a certain SP supply pressure, the cement material fills possible cracks and zones of collapse, as well as the space between the bottom of the borehole and the tip of the feeder pipe. Since the cement material cannot flow through the gap between the feeder pipe and the rock due to the size of the feeder pipe, the cement material creates a certain feed pressure TR in the well. This pressure creates a buoyancy force on the feeder tube, thereby moving the feeder tube outward in the well due to the interaction of the buoyant force and the pulling force of the actuator. The amount of cement material that must be supplied can be adjusted in various ways according to whether the rod should be cemented along its entire length or only at its inner end. When the valve pressure limit is adjusted accordingly, the supply pressure remains at such a value that the feeder pipe moves outward in the well at exactly the same speed.

    rusty, with what cement material
    fed to the well. With the help of the flow control valve 33, the rate of reverse movement of the feeder pipe can be adjusted.
    The amount of cement material fed into the well can be regulated, for example, by means of a pressure accumulator 32 and a one-way restriction valve 33, whereby a predetermined amount of pressurized oil is supplied per unit time to the pressure accumulator through the restrictor valve throttle 33. When the oil flows into the accumulator battery pressure increases accordingly. When the pressure of the accumulator increases to a certain value, the control valve 27 returns to its initial position so that the feed pump 11 and the hydraulic motbra stop. By regulating the flow of oil supplied to the accumulator, by means of the throttles of the restrictor valve 33, the delivery time and the amount of cement material fed into the well can be determined in advance. Accordingly, the adjustment can of course be made by adjusting the pressure, which causes the control valve 27 to return to its original position.
    When the lever of the control valve 26 of the actuator is pushed back, the hydraulic motor 22 continues to rotate the rollers 16 so that they move the feeder pipe to the fully removed initial position.
    The control valves can also be returned to the initial position by means of pressure pulses generated by the feeder pipe at a certain point. It is also possible to carry out operation with an electric pulse when a solenoid valve is used, for example with a flow meter.
    The operation of the device can be carried out automatically, whereby the operator only begins the feeding operation, and the device performs the feeding stage by stage, finally returning to its initial position.
    It is possible to perform control for performing the method step by step,

    e.g. from longitudinal movement. pipe feeder, from the hydraulic pressure of its feed stream, as well as when measuring the amount of cement material supplied to the well.
    In the control circuit (Fig. 10), the actuator of the feeder pipe 6 is equipped with a power cylinder 34 with a return spring. The piston of the cylinder moves the drive rollers 16 of the actuator 6 between the drive position and the idle position. The cylinder 34 is connected via a pressure controlled flow control valve to the pressure circuit of the supply motor 28.
    The control circuit operates as follows.
    The feeder pipe is introduced into the well by the motor 22 and cement material is supplied through the feeder pipe in the manner described. When the space between the bottom hole and the feeder pipe tip is filled with cement material, the filling pressure TP of the cement material causes an increase in pressure in the feed motor 28, whereby the pressurized fluid flows through valve 30 into cylinder 34. As a result, the cylinder piston pushes the drive rollers 16 actuator 6, freeing them from contact with the feeder tube so that the feeder tube can move axially relative to the actuator and thus move outwards in the well due to the filling pressure TP, acting on the feeder pipe. By moving the feeder pipe, the pressure of the cement material in the well is reduced, whereby the pressure in the feed motor circuit is reduced accordingly and the pressure in the cylinder decreases. As a consequence, the actuator drive rollers again stop the feeder tube in its position. In the third control circuit (FIG. 11), valve 30 (FIG. 9) is replaced by a solenoid valve 35, which
    connected to a pressure connector 36, which is connected to line 37 to sense the pressure of the cement material in the pipe 5 of the feeder. When the well is filled with cement, the material and the pressure in the feeder pipe increase as a result to a greater value than the normal supply pressure, the pressure connector sprinkles the impulse to the valve 35, which passes the pressurized fluid to the feeder pipe motor 22. The motor pulls the feeder tube out of
    5, whereby the supply pressure of the cement material in the feeder pipe is again reduced and provides, through the pressure connector 36, a pulse that changes the position of the valve 35 so that the motor 22
    stops. The feeder pipe moves in this way step by step outwards until the well is filled to the desired length and the pipe
    5, the feeder is not completely removed from the well by actuating control valve 26.
