Description

Technical Field

[0001] This application relates to the field of coal mine water control technology, and in particular to a precision control device for directional drilling to treat Ordovician limestone water. Background Technology

[0002] In the field of coal mine water control technology, Ordovician limestone water hazards have always been a major challenge in coal seam mining in northern coalfields. As a strong karst aquifer beneath coal seams, the Ordovician limestone's high water content and pressure make it highly vulnerable to high-pressure water from the Ordovician limestone during mining. With the continuous expansion of coal mining scale and the gradual increase in mining depth, the Ordovician limestone water hazard problem has become increasingly prominent, seriously affecting the safe production and sustainable development of coal mines. Ordovician limestone water hazards can not only lead to water inrush accidents, causing casualties and property losses, but also damage the coal mine's production environment, affect mining continuity, and restrict normal coal mine production.

[0003] To address the water hazard problem caused by Ordovician limestone formations, previous coal mine water control efforts often employed underground, through-hole, vertical-hole localized grouting reinforcement technology. This technique primarily involves drilling holes underground and injecting grout into the coal seam floor to reinforce the aquitard and prevent the inflow of Ordovician limestone water. Simultaneously, simple monitoring methods are used to track parameters such as water level and pressure. However, these conventional methods have certain limitations in practical application.

[0004] The underground cross-layer straight hole local grouting reinforcement technology has problems such as large blind spots, small scope and poor effect, making it difficult to comprehensively and effectively prevent and control Ordovician limestone water hazards, and it will also affect the mining continuity and fail to meet the needs of safe production in coal mines.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a precise control device for directional drilling to treat Ordovician limestone water, so as to overcome the shortcomings in current practical applications. Summary of the Invention

[0033] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0034] The present invention provides the following embodiments: This application discloses a precision control device for directional drilling to treat Ordovician limestone runoff, referring to... Figure 1 The system includes a directional drilling mechanism 1 for multi-angle drilling, a trajectory monitoring mechanism for real-time monitoring and correction of the drilling trajectory, and a collaborative grouting and slurry replenishment mechanism for realizing the grouting process and linkage of borehole groups. The trajectory monitoring mechanism and the collaborative grouting and slurry replenishment mechanism are set inside the directional drilling mechanism 1, achieving the effects of multi-angle drilling, real-time monitoring and correction of the trajectory, and collaborative grouting and replenishment. This is because the directional drilling mechanism 1 provides multi-angle drilling capability, the trajectory monitoring mechanism can ensure the accuracy of the drilling trajectory, and the collaborative grouting and slurry replenishment mechanism can achieve efficient grouting and replenishment. The three work together to improve the accuracy and effectiveness of Ordovician limestone water treatment.

[0035] Specifically, the directional drilling mechanism 1 includes a connecting component 11, a fixing component 12, a drilling component 13, and a guiding component 14.

[0036] Reference Figure 1 , Figure 2The connecting component 11 includes a protective hose 111, which is generally made of high-strength, wear-resistant rubber, possessing good flexibility and corrosion resistance to protect internal components. A snap-fit ​​ring 112 is located at the top of the protective hose 111, typically made of metal such as stainless steel, and is installed at the top of the protective hose 111 by welding or integral molding. The snap-fit ​​ring 112 is rotatably mounted at the bottom of the fixing component 12, allowing the protective hose 111 to rotate freely relative to the fixing component 12. A slurry-passing hose 113 is installed inside the protective hose 111. The slurry-passing hose 113 can be made of nylon, offering good high-pressure resistance. A cable layer 114 for placing cables is formed between the slurry-passing hose 113 and the protective hose 111. The cables can be copper core cables, offering good conductivity. Alternatively, the slurry-passing hose 113 can be replaced with a silicone tube, which offers better high-temperature resistance and flexibility.

[0037] The fixing component 12 includes a fixing base 121, which is generally made of cast iron and has high strength and stability. A hydraulic motor 122 is fixedly installed inside the fixing base 121. The hydraulic motor 122 is fixed inside the fixing base 121 by bolts or other means and is electrically connected to a cable for power operation. A slurry inlet at the bottom of the hydraulic motor 122 communicates with a slurry hose 113, allowing slurry to enter the hydraulic motor 122. The drive end of the hydraulic motor 122 passes through the fixing base 121 and is fixedly connected to the drilling component 13, enabling it to operate. A first slurry discharge pipe 123 is provided on one side of the fixing base 121. The first slurry discharge pipe 123 is generally made of steel pipe, with one end communicating with the slurry discharge port of the hydraulic motor 122. The first slurry discharge pipe 123 communicates with the drilling component 13, transporting the slurry discharged by the hydraulic motor 122 to the drilling component 13. Alternatively, an electric motor can be used instead of the hydraulic motor 122, as electric motors offer more precise speed control.

[0038] The drilling assembly 13 includes a drill bit 133, which is typically made of cemented carbide and has high hardness and wear resistance. Multiple drill teeth 131 are provided on the outside of the drill bit 133, which can increase the drilling efficiency of the drill bit 133. Multiple grout nozzles 132 for injecting pressurized grout are provided on the drill bit 133, and the grout nozzles 132 are located between pairs of drill teeth 131, allowing the high-pressure grout to better assist drilling. The drill bit 133 has a first slurry passage chamber 1331 at one end facing the fixed base 121. The bottom of the first slurry passage chamber 1331 has a first rotating groove 1332 and a first limiting groove 1333. A first sealing plate 1334 is mounted inside the first rotating groove 1332. The first sealing plate 1334 is generally made of metal, and a first insert plate 1335 is mounted on its outer side. The first insert plate 1335 is inserted into the first limiting groove 1333, preventing the first sealing plate 1334 from detaching. A first insertion port 1336 is provided on the first sealing plate 1334. The other end of the first slurry discharge pipe 123 is inserted into the first insertion port 1336 and communicates with the first slurry passage chamber 1331, allowing slurry to enter the first slurry passage chamber 1331. The drill bit 133 has a first slurry chamber 1337. A hydraulic pump 1338 is fixedly installed inside the drill bit 133 by bolts, and its slurry inlet is connected to the first slurry chamber 1337. The drill bit 133 also has a second slurry passage chamber 1339, which is connected to the outlet of the hydraulic pump 1338 through a second slurry chamber 1340. The second slurry chamber 1340 is connected to multiple slurry nozzles 132, which can deliver slurry to the nozzles. The drill bit 133 also has a drive unit 1341, which is generally a small motor. Its drive end passes through the drill bit 133 and is fixedly connected to the guide assembly 14, enabling the guide assembly 14 to operate. The drill bit 133 is equipped with a second slurry pipe 1342. One end of the second slurry pipe 1342 is connected to another outlet of the hydraulic pump 1338, and the other end is connected to the guide assembly 14, which can deliver slurry to the guide assembly 14. The drive component 1341 here can also be replaced by a pneumatic motor, which has better explosion-proof performance.

[0039] The guide assembly 14 includes a guide seat 141, which is typically made of aluminum alloy, giving it a light weight and good strength. A guide ramp 142 is provided on the guide seat 141, guiding the drilling direction of the drill bit 133. A clearance groove 1421 is formed between the guide ramps 142, and a nozzle 1422 is provided within the clearance groove 1421 to spray slurry to assist drilling. A third slurry passage chamber 143 is formed at the end of the guide seat 141 facing the drill bit 133. A second rotating groove 1431 and a second limiting groove 1432 are formed at the bottom of the third slurry passage chamber 143. A second sealing plate 144 is arranged within the second rotating groove 1431, and a second insert plate 145 is provided on the outer side of the second sealing plate 144. The second insert plate 145 is inserted into the second limiting groove 1432, preventing the second sealing plate 144 from dislodging. The second sealing plate 144 has a second insertion port 146, and the other end of the second slurry discharge pipe 1342 is connected to the second insertion port 146. The third slurry passage chamber 143 is connected to the nozzle 1422, which can deliver slurry to the nozzle 1422. The guide seat 141 here can also be made of ceramic material, which has better wear resistance.

[0040] Reference Figure 2 , Figure 3 The limit module 147 is driven by slurry pressure. When the guide seat 141 does not need to rotate, the hydraulic pump 1338 increases the slurry pressure to a predetermined value. The push plate 1473 in the second slurry chamber 1339 is pushed by the pressure, and the push plate 1473 moves towards the guide seat 141. The sleeve 1476 and the locked gear 1475 move towards the guide seat 141 simultaneously. The return spring 1481 is compressed, and the locking groove 1480 locks the locked gear 1475. The block 1477, the second rotating column 1478, and the first The second gear 1479 cannot rotate. The second gear 1479 locks the first gear 1471, preventing the unpowered first gear 1471 from rotating arbitrarily in the drive cavity 1472 and affecting the guiding direction of the guide seat 141. When it is necessary to rotate the guide seat 141, the slurry pressure is reduced so that the guide seat 141 can rotate freely. The locked gear 1475 separates from the locking groove 1480, and the second gear 1479 rotates freely with the first gear 1471. The guide seat 141 rotates freely to guide, improving the stability and directional accuracy of drilling.

[0041] Reference Figure 1 , Figure 2The combined logic of the connecting component 11, fixing component 12, drilling component 13, and guiding component 14 is as follows: Slurry is delivered to the hydraulic motor 122 via the protective hose 111 and the slurry-passing hose 113. The hydraulic motor 122 drives the drilling component 13 to operate. The drill bit 133 of the drilling component 13 rotates and drills under the drive of the driving component 1341. Simultaneously, the hydraulic pump 1338 delivers slurry to the slurry nozzle 132 and the guiding component 14. The guiding component 14 guides the drilling direction, thereby achieving multi-angle drilling. This combination enables the entire directional drilling mechanism 1 to operate efficiently and stably, improving drilling efficiency and accuracy.

[0042] The trajectory monitoring mechanism includes a dual-module collaborative monitoring unit and an automatic correction unit, both housed within the guide seat 141. The dual-module collaborative monitoring unit integrates a gyroscope and a magnetic sensor. The gyroscope accurately measures the angle and angular velocity of the guide seat 141, while the magnetic sensor detects the direction and intensity of the magnetic field. Their collaborative operation accurately acquires drilling trajectory information. The automatic correction unit adjusts the deflection angle of the directional drilling component 13 based on the dual-module monitoring data, ensuring the drilling trajectory meets expectations. Alternatively, an accelerometer can be used instead of a gyroscope, as it measures acceleration and can also assist in monitoring the drilling trajectory.

[0043] The grouting monitoring and control mechanism includes a pressure sensor for detecting changes in grouting pressure. The pressure sensor is electrically connected to a hydraulic pump 1338. The pressure sensor monitors the grouting pressure in real time. When the pressure changes, it transmits a signal to the hydraulic pump 1338, which adjusts the grouting volume accordingly, thus achieving coordinated grouting of the borehole group. Alternatively, a differential pressure sensor can be used instead, as it can measure pressure changes more accurately.

[0044] The implementation principle of this embodiment is as follows: the device achieves multi-angle drilling through the directional drilling mechanism 1, which can adapt to complex geological conditions. The trajectory monitoring mechanism monitors and corrects the drilling trajectory in real time to ensure the accuracy of drilling. The exploration, dredging, injection and monitoring coordination mechanism realizes grouting of the borehole group and linkage grouting according to the change of grouting pressure, which improves the accuracy and efficiency of Ordovician limestone water treatment. Compared with the traditional Ordovician limestone water treatment method, it can better meet the actual needs and reduce the safety hazards and economic losses caused by the sudden surge of Ordovician limestone water.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
