What matters should be noted when using pneumatic coal mine anchor drill RIGS?
If the selection of the pneumatic anchor drill is correct, the direct cause of the drill blockage is that the drilling torque and the thrust force are not properly matched. This is because the two control valves that control the rotation of the motor and the advancement of the outriggers are both stepless speed control valves. During the drilling process, the operator of the pneumatic anchor drill needs to adjust these two valves at any time to ensure that the pneumatic anchor drill can perform well when the roof conditions change. Timely adjustment should be made to ensure that the matching value of the torque and propulsion force of the pneumatic anchor drill rig varies with the changes in the roof slab. Only in this way can the phenomenon of clogged drill be avoided and reduced. If, regardless of whether the roof changes or not, and regardless of whether the torque and propulsion force match, one keeps drilling down until no more can be drilled, this will inevitably lead to a blocked drill.
During the operation of the pneumatic anchor drill rig, it is strictly prohibited for operators or staff to touch the rotating drill pipe. When drilling holes, it is not allowed to wear gloves to hold the working drill pipe.
2. After the drill pipe of the pneumatic anchor drill rig reaches the top plate, the motor wrench should be pressed down and the water control knob should be turned on simultaneously to start the drilling operation. The control of the motor and water should be adjusted in time to gradually increase the rotational speed of the drill pipe and the advancing speed to the maximum value. At the same time, the advancing speed and force should be appropriate.
However, it should be noted that in the case of working on soft rock, the pneumatic anchor drill rig requires a relatively high rotational speed and a relatively small thrust. In the working environment of hard rock, the required rotational speed of pneumatic anchor drill RIGS is relatively low. Under such circumstances, the thrust of the outriggers can be gradually increased to achieve the desired drilling speed. During the drilling process of argillaceous rock, special attention should be paid to water pressure. If the water output is relatively small during operation, the motor should be stopped, and the water should be flushed before resuming the operation.
During the operation of the pneumatic anchor drill, if the drill suddenly gets stuck, it will cause a large reverse torsion. At this time, the operator needs to pay special attention to prevent being twisted by the reverse torsion force.
4. During the drilling process of the pneumatic anchor drill rig, the drill pipe and the drill rig must not be tilted relative to each other, and the water flow must not be interrupted. No one is allowed to stand in front of the drill rig during the drilling process to prevent accidents.
During the operation of the pneumatic anchor drill rig, the operator should follow the centerline of the borehole to prevent the drill rod from breaking and causing unnecessary accidents.
