Description

Technical Field

[0001] The invention relates to an intelligent drilling pressure relief device for mining and a use method thereof, belonging to the technical field of coal mining equipment. Background Art

[0002] As the main energy source in my country, coal occupies an important strategic position in the national economy. In the next few decades, the energy structure dominated by coal will be difficult to change. With the intensification of coal mining, shallow resources are gradually exhausted, and coal development is accelerating to shift to deep and complex geological conditions, resulting in complex and difficult tunnels such as kilometer-deep well high-ground stress tunnels, extremely broken surrounding rock tunnels, tunnels with large sections, tunnels affected by strong mining, and tunnels left along the goaf. In view of the increasingly complex geological conditions and the gradual increase in the instability of ground pressure, how to maintain stable tunnel pressure and prevent impact ground pressure has become a prominent issue.

[0003] Borehole pressure relief is a measure to eliminate or mitigate rock impact by drilling. This method is based on the drilling impact phenomenon generated when drilling with construction cuttings. The deeper the drilling is into the inductive force zone, the higher the frequency and intensity of the drilling impact, and the amount of coal powder increases significantly during drilling impact. Therefore, each borehole will form a certain crushing zone. When these crushing zones are close to each other, the coal seam can be broken and pressure relieved.

[0004] The current drilling pressure relief work mainly relies on manpower or manually operated machines to enter the tunnel to drill holes, which is labor-intensive and has great safety hazards.

[0005] Chinese patent document CN109898994A discloses a coal seam pressure relief method, which uses a drilling rig to drill holes on the coal seam to obtain a pressure relief series channel, expands the end of the pressure relief series channel to obtain a first pressure relief space, expands the hole at a first distance from the center of the first pressure relief space along the axis of the pressure relief series channel to obtain a second pressure relief space, and the invention also discloses a pressure relief device for performing the coal seam pressure relief method. The device uses a manually operated drilling rig for drilling operations, which has high labor intensity and long working time.

[0006] Chinese patent document CN209179794U discloses a fully hydraulic coal mine underground tunnel anchor drilling device, including a device body, a lifting hydraulic telescopic rod is provided at the lower end of the device body, a connecting plate is provided at the lower end of the lifting hydraulic telescopic rod, a fixed threaded hole is provided on one side of the lifting hydraulic telescopic rod on the upper end outer surface of the connecting plate, a load-bearing threaded column is provided on the inner side of the fixed threaded hole, a rotating disk is provided on the upper end of the load-bearing threaded column, an anti-sliding block is provided on one side of the rotating disk, a fixed plate is provided at the lower end of the load-bearing threaded column, and a load-bearing universal wheel is provided on one side of the load-bearing threaded column at the lower end of the connecting plate. The device uses manual operation to adjust the height before drilling, and the intelligence level is low, and it cannot avoid the risks that may be caused by personnel operating underground.

[0007] In view of this, it is very necessary to design an intelligent, automated and efficient drilling pressure relief device, which can effectively reduce the pressure relief workload, facilitate construction, increase construction speed and not affect the construction period. Summary of the invention

The deformation scanner monitors the upper area, left area, and right area of ​​the tunnel after deformation in real time and records them as S0 respectively. ’ 、S1 ’ 、S2 ’ , when {[(S0+S1+S2)-(S0 ’ +S1 ’ +S2 ’ )] / S0+S1+S2}×100%≥10%, the device stops moving;

When the extended length of the drilling motor reaches the set value, the drilling motor stops. After being stationary for 3 seconds, the drill bit reverses, and the telescopic hydraulic cylinder retracts the drilling motor, allowing the drill bit to exit smoothly.

[0030] (5) The drilling motor returns to its original position, the hydraulic support device is retracted, and the device returns to its original position and continues to move forward. When the data monitored by the deformation scanner meets the working conditions, steps (3) and (4) are repeated.
