Description

Technical Field

[0001] This invention relates to the field of internal slag discharge drilling technology, specifically to an integrated device for large-diameter internal slag discharge deep hole pressure relief directional drilling and pumping. Background Technology

[0002] For mines characterized by high coal seam gas content, low gas permeability, and soft coal quality, directional drilling technology is employed for drilling. This technology allows for precise control of the drilling direction and angle, utilizing high-pressure water flow to physically cut and expand fractures in the coal seam, creating gas release channels. Multi-point extraction is achieved through branch holes, thereby improving gas extraction efficiency. However, current equipment suffers from the following bottlenecks: 1) Separation of drilling and extraction: Drilling and extraction must be carried out in separate steps, resulting in a long work chain and low efficiency; 2) Lack of wall protection: Mud slurry cannot be used for wall protection simultaneously, leading to easy borehole collapse; 3) Water-gas imbalance: Lack of coordinated control between water injection and gas extraction; insufficient water level during extraction leads to excessively high gas concentrations, and the inability to automatically adjust pump pressure or extraction negative pressure; 4) Blind monitoring: Lack of real-time automatic monitoring makes it difficult to promptly identify drill bit wear, blockage, and abnormal propulsion resistance, causing a sharp drop in drilling efficiency and drill rod overload. Therefore, we propose a large-diameter, internally discharged, deep-hole pressure-relief directional drilling and extraction integrated device. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention employs a detachable sealed stud, facilitating gas extraction after disassembly and enabling switching between drilling and extraction. Its simple structure ensures high-quality gas venting. The drill rod itself can extract gas, allowing for rapid drilling and cleaning even in cases of partial borehole collapse, ensuring normal gas extraction and a high success rate. It eliminates the need for subsequent reinsertion of the gas extraction pipe. The retractable oscillating drill teeth facilitate easy insertion and removal from the sealing sleeve, ensuring the actual borehole diameter exceeds the drill rod's size and maintaining normal water pressure flow. The external water injection and pressurization method on the drill rod acts as a mud wall protector, enhancing the borehole's anti-collapse effect.

[0016] The water storage confirmation device can be used for real-time control during gas extraction. It is necessary to ensure that water is injected and gas is discharged simultaneously to improve safety and reduce safety hazards. By using water injection, the concentration of gas emissions is reduced. It can automatically detect and control and stop emissions when water is scarce. Water injection penetrates the pores of the coal body, directly reducing the content of free gas. At the same time, wetting the coal body reduces the generation of frictional sparks and can automatically maintain the water injection level at the standard.

[0017] Using a breakage detection device can automatically detect drilling debris. If there is too little drilling debris, that is, if the drill bit is worn or clogged, it can be detected automatically. Once the drill bit is worn or clogged, its drilling speed decreases, but the drilling rig continues to push forward normally. At this time, the pressure on the drill rod will increase. When drilling deeper, the bending deformation of a row of drill rods will increase, increasing the pressure on the borehole wall and increasing wear. The breakage detection device can remind the staff to carry out timely maintenance and to stop drilling. Attached Figure Description

[0033] The drilling and pumping sealing component 1 further includes: a water hood 103, a water supply pipe 104, and a cover 105. The water hood 103 is fixedly installed on the sealing installation cylinder 101; the water hood 103 is connected to a ring of through holes on the sealing installation cylinder 101; the water supply pipe 104 is fixedly installed at the bottom of the water hood 103; a water pump is connected to the water supply pipe 104; the water hood 103 is threaded; the cover 105 is connected to the water hood 103 by a steel wire rope, and the cover 105 is threaded onto the water hood 103. The drilling and pumping control component 2 includes: a drill rod 201 and a sealing stud 202. The drill rod 201 is arranged in a row, and the drill rods 201 in the row are threaded together; the sealing installation cylinder 101 is sleeved on the row of drill rods 201; the row of drill rods 201 is threaded with sealing studs 202 respectively. The closed stud 202 has a hexagonal hole; a row of drill rods 201 each has a groove for connecting a wrench; the drilling control component 3 includes: a drill bit 301, a water passage hole 3011, fixed drill teeth 302, oscillating drill teeth 303, and a pullback spring 304. The drill bit 301 is threaded to the front end of the drill rod 201 at the end; the drill bit 301 has two water passage holes 3011; the water passage holes 3011 connect to the drill rod 201; two rows of fixed drill teeth 302 are symmetrically fixedly installed on the drill bit 301 by bolts; two oscillating drill teeth 303 are rotatably installed on the drill bit 301, and pullback springs 304 are fixedly installed on the sides of the two oscillating drill teeth 303 respectively, and the ends of the two pullback springs 304 are fixedly installed on the drill bit 301 respectively; the pullback spring 304 is a V-shaped elastic steel sheet structure;The pull-back spring 304 is used to apply elastic contraction force to pull the oscillating drill teeth 303 outward, and the drilling diameter when the oscillating drill teeth 303 are outward is larger than the diameter of the drill bit 301. The drill extraction control component 2 can be used to control directional drilling in coal seams through the drilling rig. At the same time, the detachable sealing stud 202 can be used to facilitate gas extraction after disassembly, realize the switching between drilling and extraction, and ensure the quality of gas exhaust. The drill extraction sealing component 1 can be used to seal the end of the borehole, and can be used to supply pressure after water flows from the outside of the drill rod 201, and to remove slag through the inside of the drill rod 201. The internal cavity allows for smoother flow of drilling cuttings, reducing the likelihood of blockages. The retractable oscillating drill teeth 303 facilitate easy insertion and removal from the sealing sleeve 101, ensuring the actual borehole diameter exceeds the drill rod 201 and maintaining normal water pressure flow. The external water injection and pressurization of the drill rod 201 acts as mud wall protection, enhancing the borehole's anti-collapse effect. Furthermore, this structure facilitates drill bit 301 replacement. When replacement is time-consuming, the drill bit 301 can be directly extracted and manually connected to the cover 105 via thread. The water cover 103 is equipped with an auxiliary seal to prevent impurities and gravel from entering, resulting in a more rational structure. It utilizes fixed drill teeth 302 and oscillating drill teeth 303 for coal seam drilling. The pull-back spring 304 and the oscillating drill teeth 303 with their inner inclined structure enable outward drilling. Simultaneously, the oscillating drill teeth 303, which can be elastically rotated and adjusted, are squeezed by the edge of the sealing installation cylinder 101 when pulled out, achieving shrinkage without affecting disassembly and assembly. Meanwhile, with the continuous water pressure supplied by the water pump connected to the water supply pipe 104, water flows from the front end of the drill bit 301 and the water passage 3011. Inside drill bit 301, cuttings generated during drilling flow through drill rod 201 and are drawn out by a water pump connected to suction pipe 502, achieving internal cuttings removal. Simultaneously, after drilling is complete, the sealing studs 202 on a row of drill rods 201 can be disassembled sequentially. The screw holes on drill rod 201 are then used for ventilation and gas flow. Utilizing the gas extraction structure of drill rod 201 itself, even with partial borehole collapse, it can be quickly drilled and cleaned with drill bit 301, ensuring normal gas extraction and guaranteeing a high success rate. There is no need to subsequently reinsert the gas extraction pipe.

[0034] The closed control component 4 includes: a drilling rig connecting cylinder 401, a discharge groove 4011, and an indicator light 402. The tail of the drilling rig connecting cylinder 401 is used to insert the drilling rig; the drilling rig connecting cylinder 401 is threaded onto the drill rod 201 at the tail; a discharge groove 4011 is formed on the drilling rig connecting cylinder 401; an indicator light 402 is fixedly installed on the drilling rig connecting cylinder 401. The suction auxiliary component 5 includes: a suction connecting cover 501 and a suction connecting pipe 502. The suction connecting cover 501 is rotatably sleeved on the drilling rig connecting cylinder 401; a suction connecting pipe 502 is fixedly installed at the bottom of the suction connecting cover 501; a solenoid valve is provided on the suction connecting pipe 502; a water pump is connected to the outside of the suction connecting pipe 502; a switch is connected to the solenoid valve provided on the suction connecting pipe 502; the suction connection... The receiving cover 501 is used for pumping drilling debris and gas; the water storage confirmation component 6 includes: a water storage confirmation shell 601, a lifting column 602, and a water storage switch 603. The water storage confirmation shell 601 is fixedly installed on the suction connection cover 501; the lifting column 602 is slidably sleeved inside the water storage confirmation shell 601; a spring is sleeved inside the water storage confirmation shell 601, and the spring inside the water storage confirmation shell 601 is connected between the water storage confirmation shell 601 and the lifting column 602; the water storage switch 603 is fixedly installed inside the water storage confirmation shell 601, and the end of the lifting column 602 is aligned with the water storage switch 603; the water storage switch 603 is located above the suction connection pipe 502; the water storage confirmation component 6 also includes: a buoyancy control block 604, which is fixedly installed at the bottom of the lifting column 602. The buoyancy control block 604 is used to detect the water filling inside the suction connection cover 501; the water storage switch 603 is electrically connected to the solenoid valve on the suction connection pipe 502. The suction auxiliary component 5 ensures that the suction auxiliary component 5 can normally perform the suction of drilling debris or gas during the real-time rotation of the closed control component 4. Simultaneously, this structure, in conjunction with the water storage confirmation component 6, can be used for real-time control. When extracting gas, it is necessary to ensure that water is injected while gas is discharged, improving safety and reducing safety hazards. By using water injection, the gas emission concentration is reduced. Automatic detection and control can be performed to stop emission when water is insufficient. Water injection penetrates the pores of the coal body, directly reducing the free gas content, while simultaneously wetting the coal body to reduce frictional sparks. The suction connection pipe 5 can be manually controlled first. The solenoid valve on 02 is connected to a switch to open the suction connection pipe 502. At this time, the suction connection pipe 502 normally discharges and injects water. At the same time, the liquid level inside the suction connection cover 501 will rise. The buoyancy pushes the buoyancy control block 604 to push the lifting column 602 upward and squeeze the water storage switch 603. Conversely, if the water level inside the suction connection cover 501 is insufficient, the water level inside the suction connection cover 501 will drop, which can control the solenoid valve on the suction connection pipe 502 to close. After the water level rises, the solenoid valve on the suction connection pipe 502 can be controlled to open, so that the injected water and gas are discharged together. This ensures that water can be supplied at the same time when discharging gas, thereby improving the safety of gas discharge. By monitoring the liquid level, the quality of gas venting and depressurization is guaranteed, and the gas is fully released.

[0035] In Example 2, based on Example 1, the breakage detection component 7 includes: a retraction control cylinder 701 and an umbrella-shaped mesh cover 7011. The retraction control cylinder 701 is slidably inserted into the drill connecting cylinder 401. A spring is fixedly installed at the tail of the retraction control cylinder 701, and the spring end at the tail of the retraction control cylinder 701 is connected to the inside of the drill connecting cylinder 401. An umbrella-shaped mesh cover 7011 is fixedly installed at the front end of the retraction control cylinder 701, and the umbrella-shaped mesh cover 7011 has a sloping structure. A through groove is provided on the umbrella-shaped mesh cover 7011. The through groove on the umbrella-shaped mesh cover 7011 is used to stop the crushed stone. 11 is located in front of a discharge trough 4011; the breakage detection component 7 also includes: a switch mounting cylinder 702 and a warning switch 703. The switch mounting cylinder 702 is slidably sleeved on the retraction control cylinder 701, and a spring is sleeved inside the switch mounting cylinder 702. The spring inside the switch mounting cylinder 702 is connected between the switch mounting cylinder 702 and the retraction control cylinder 701. The warning switch 703 is fixedly installed at the end of the switch mounting cylinder 702, and the warning switch 703 is used to press and fit against the inside of the drilling rig connecting cylinder 401. The warning switch 703 is electrically connected to the indicator light 402. The breakage detection component 7 can be used to... To achieve automatic detection of drilling debris, the system can automatically detect insufficient drilling debris, indicating excessive wear or blockage of drill bit 301. It utilizes the principle that drilling debris adhering to the umbrella-shaped mesh cover 7011 increases water flow resistance, prompting personnel to check drill bit 301, thus ensuring drilling quality. Simultaneously, when drill bit 301 is excessively worn or blocked, its drilling speed decreases while the drilling rig continues to advance with normal force. This increases the pressure on drill rod 201. During deeper drilling, the increased bending deformation of the row of drill rods 201 increases the pressure on the hole. The pressure on the wall increases wear. The breakage detection component 7 can prompt the staff to carry out timely maintenance and stop drilling. If the drilling produces too little debris, the debris blocked by the umbrella-shaped mesh cover 7011 will be reduced, and the resistance of the umbrella-shaped mesh cover 7011 to the water flow will be reduced, allowing the water to flow quickly. At this time, under the compression of the spring at the tail of the retraction control cylinder 701, the umbrella-shaped mesh cover 7011 can be pushed forward, causing the indicator switch 703 to stop pressing against the inside of the drilling rig connecting cylinder 401, so that the control indicator light 402 goes out, and the staff can carry out maintenance work in time.

[0036] The working principle of this embodiment is as follows: First, when drilling to extract gas, a hole is first drilled downwards on the sidewall of the roadway, and then the sealing installation cylinder 101 is inserted. Then, the grouting anchor rod is passed through the through hole on the sealing plate 102 for anchoring. Subsequently, the drill bit 301 is inserted into the sealing installation cylinder 101 through the water hood 103. During the process, the two swing drill teeth 303 can be manually squeezed together to ensure normal insertion. The tail of the drilling rig connecting cylinder 401 is used to insert the drilling rig, and the drill rod 201 is threadedly connected to the drilling rig connecting cylinder. Assembled in section 401, drill rod 201 is advanced by rotating the drill rig. As the drilling depth of drill rod 201 increases, it can be detached from the drill rig connecting sleeve 401 by rotation. A wrench can be used to connect the new drill rod 201 between the existing drill rod 201 and the drill rig connecting sleeve 401, achieving lengthening, consistent with existing technology. As drill bit 301 rotates, fixed drill teeth 302 and oscillating drill teeth 303 are used to drill into the coal seam, aided by the pulling action of the pullback spring 304 and the inner inclined... The oscillating drill bit 303 with a faceted structure can achieve outward drilling. Simultaneously, the oscillating drill bit 303, which can be elastically rotated and adjusted, can be squeezed by the edge of the sealing and mounting cylinder 101 when pulled out, achieving shrinkage without affecting disassembly and assembly. Meanwhile, with the water pump connected to the water supply pipe 104 continuously supplying water pressure, water flows from the front end of the drill bit 301 and the water passage 3011 into the interior of the drill bit 301, carrying the drilling debris generated by the drill bit 301 through the drill rod 201, and flowing through the suction connection pipe. The external suction pump connected to 502 draws water to achieve internal slag discharge. The external suction pump connected to the suction connection pipe 502 is placed on the ground and the outlet is led out of the mine. At this time, with the suction connection pipe 502 and the counterweight of the external suction pump, the suction connection cover 501 is kept stable. As the drilling rig connection cylinder 401 rotates, the drilling debris is discharged through the discharge trough 4011 and drawn by the external suction pump connected to the suction connection pipe 502. The suction connection pipe 502 can remain in a vertical position and does not rotate with the drilling rig connection cylinder 401.

[0037] During normal drilling, a large amount of debris adheres to the umbrella-shaped screen 7011. Combined with water pressure, the umbrella-shaped screen 7011 and the retraction control cylinder 701 retract, compressing the spring at the tail end and no longer obstructing the front of the discharge groove 4011. At this point, the debris can be discharged normally from the discharge groove 4011. The switch mounting cylinder 702 is also driven to retract, and the indicator switch 703 presses against the inside of the drilling rig connecting cylinder 401, compressing the spring inside the switch mounting cylinder 702. The control indicator light 402 illuminates as a warning. Conversely, if the spring is not compressed, the spring is compressed. When there is too little cuttings produced during drilling, the amount of cuttings blocked by the umbrella-shaped mesh cover 7011 is directly reduced, and the resistance of the umbrella-shaped mesh cover 7011 to the water flow is reduced, allowing the water to flow quickly. At this time, under the compression of the spring at the tail of the retraction control cylinder 701, the umbrella-shaped mesh cover 7011 can be pushed forward, causing the indicator switch 703 to stop pressing against the inside of the drilling rig connecting cylinder 401, so that the control indicator light 402 goes out to indicate maintenance. The diameter of the stone particles produced by drilling is small and will not get stuck or blocked on the umbrella-shaped mesh cover 7011.

[0038] After drilling is completed, remove a row of drill rods 201 and directly remove the sealing studs 202 on each row of drill rods 201 in sequence. At this time, the screw holes on the drill rods 201 are used for ventilation and gas flow. Then, insert the row of drill rods 201 into the borehole. While releasing gas, water can also be injected in real time. The water is discharged from the discharge tank 4011 to the suction connection cover 501. The solenoid valve on the suction connection pipe 502 can be manually controlled to open the suction connection pipe 502. At this time, the suction connection pipe 502 normally discharges and injects water. At the same time, the liquid level inside the suction connection cover 501 will rise, and the buoyancy will push the buoyancy control block 604. Pushing the lifting column 602 upwards squeezes the water storage switch 603 to control the solenoid valve on the suction connection pipe 502 to open and allow water to flow. Conversely, if the water pressure supply is insufficient due to factors such as excessive coal seam leakage or partial blockage of the water inlet, resulting in insufficient water volume inside the suction connection cover 501 and drill rod 201, and gas is prone to overflow directly, the water level inside the suction connection cover 501 will drop, which can control the solenoid valve on the suction connection pipe 502 to close. Only after the water level rises can the solenoid valve on the suction connection pipe 502 be opened, so that the injected water and gas can be discharged together, ensuring that water can be supplied simultaneously when discharging gas.
