Technical Field

[0001] The device for treating dust and gas in gas drainage holes by fluid modification of water particle groups of the present invention belongs to the technical field of gas drainage in coal mines, and specifically relates to a device that generates changes in surface tension and interfacial polarity effects through the relative movement of the air-dynamic force and the water particle group interface, and further enhances the interfacial polarization effect in the presence of a large number of carbon dust particles, so that the aerosol dynamic fluid can simultaneously treat the dust and gas at the source. The device has a simple structure, is convenient to operate, and has reliable performance. The key is that it can treat dust and gas simultaneously by the dynamic fluid. Background Art

[0002] Underground gas is one of the main disasters in Chinese coal mines. High-gas and gas-outburst coal mines account for 46% of the total number of coal mines in China. Due to the high difficulty of gas control and many disaster factors, mine gas has always been the focus and difficulty of coal mine safety work in China. The traditional method for extracting coalbed methane is to extract coalbed methane through drilling and drainage technologies. In the field of deep coal extraction, the coal seam is enclosed in a closed space by rock layers and contains gas. Therefore, the existing technology adopts the strategy of first extracting gas and then mining coal for deep coal extraction. Due to the extremely high hardness of the rock layer, the drilling difficulty is high. The existing technology mostly uses drill bits for drilling, and the working efficiency is also very low. The hardness of the coal seam is slightly lower, and although the fragmentation difficulty is reduced, directly using a drill bit is likely to ignite the gas and cause a gas explosion. Moreover, inevitably, a large amount of dust pollution is generated during the drilling process. In this way, the combination of gas and dust greatly increases the necessity and urgency of the control work. When controlling gas, dust is generated, and the controlled dust can also ignite the gas, resulting in a vicious cycle of contradictions and becoming a hot topic and a difficult problem that urgently needs to be solved in the industry. Application No. CN202311464424.9, a device and method for extracting and separating gas and solid in a roadway by using liquid nitrogen for gas drilling, the invention device includes a drill bit assembly, a drilling rig, a liquid nitrogen machine, a liquid nitrogen pump, and a drill bit casing. The drill bit casing is hermetically inserted into the drill hole in the rock layer. The drill pipe is hermetically connected to the outer end of the drill bit casing. The side of the rear end of the drill bit casing is connected to a gas-solid separation tank through Valve A. The gas-solid separation tank is connected to the liquid nitrogen machine through Valve B. The liquid nitrogen machine separates nitrogen and gas and then liquefies the nitrogen. The gas is injected into the gas pipeline. The invention uses the method of injecting nitrogen to carry the gas out of the drill hole, and then separates and collects the gas. It does not treat the dust in the whole process and is very easy to bring it into the gas-nitrogen mixture. In fact, this control measure is very cumbersome and incomplete, and it is almost impossible to separate due to the existence of dust. Application No. CN202311469602.7, a gas extraction device and method based on hydraulic fracturing and dissolution of coal seams by drilling, includes a fresh water tank, a chemical solution tank, a high-pressure hydraulic fracturing pump, a purification tank, a sedimentation and filtration tank, high-pressure valves, a high-pressure water pipe 1, and a high-pressure water pipe 2. During extraction, first drill holes in the rock layer and coal seam, and the drill holes penetrate the rock layer and reach the coal seam. Use the above device to inject high-pressure water into the drill holes, and use the action of hydraulic fracturing to crack the coal seam and form a gas pressure relief channel in the coal seam. Then inject chemical solution to make the chemical solution circulate in a closed loop among the fracturing holes, hydraulic fracturing paths, control holes, sedimentation and filtration tanks, purification tanks, and chemical solution tanks, improve the utilization efficiency of the chemical solution, reduce environmental pollution, and promote the release and extraction of gas. The collection of hydraulic fracturing plus chemical solution can only operate in a closed system. The actual drilling conditions are complex and changeable. From the perspective of chemical solution pollution, pollution is inevitable, and the application scenarios will be greatly reduced. Therefore, what is urgently needed on-site is a device that can simultaneously control dust and drilling gas, is simple, reliable, and easy to implement. Summary of the Invention

The water particle group coarse adjuster 16 dynamically adjusts the size range of the water output of the tapered contact surface by adjusting the spring adjustment button thereon, thereby providing a dynamically variable turbulent water volume for the interaction process between the pressure gas and the water particle group; the fluid for controlling dust and gas in the gas extraction hole is connected to the gas extraction hole drilling rig 11 through the fluid access device 6 for controlling dust and gas in the gas extraction hole on the right side of the fluid generator 5 for controlling dust and gas in the gas extraction hole, and the gas extraction is controlled. The fluid access device 6 for controlling dust and gas in the extraction hole is fixed on the fixed plate beside the left handle of the gas extraction hole drilling machine 11. The inlet of the fluid access device 6 for controlling dust and gas in the gas extraction hole is sealedly connected with the fluid generator 5 for controlling dust and gas in the gas extraction hole fixed on the fixed plate beside the right handle of the gas extraction hole drilling machine 11 through a stainless steel metal pipe 7 with an inner hole diameter of 8 mm. The outlet of the fluid access device 6 for controlling dust and gas in the gas extraction hole is connected to the inlet end of the power rotary output part fixed on the gas extraction hole drilling machine 11 through a metal pipe with a diameter of 3.5-5 mm and is connected with a rotary dynamic seal. The outlet of the fluid access device 6 for controlling dust and gas in the gas extraction hole is connected to the inlet end of the power rotary output part fixed on the gas extraction hole drilling machine 11 through a metal pipe with a diameter of 3.A fluid polarity intensity ultrasonic detector 21 is vertically installed on a 5 - 5 mm metal pipe. The fluid polarity intensity ultrasonic detector 21 feeds back the collected polarization intensity data to the water particle group coarse adjuster 16. The water particle group coarse adjuster 16 dynamically adjusts the water output range of the taper contact surface by adjusting the spring adjustment knob on it, so as to provide a dynamically variable turbulent water volume for the interaction process between the pressurized gas and the water particle group, and control the fluid polarization intensity of the fluid generator 5 for treating dust and gas in the gas drainage hole. The outlet end of the power rotation output part fixed on the gas drainage hole drilling rig 11 is a hollow outer trapezoidal thread with a diameter of 3.5 - 5 mm for a quarter - inch pipe. The power rotation output part fixed on the gas drainage hole drilling rig 11 is a hollow outer trapezoidal thread with a diameter for a quarter - inch pipe, which is connected to the quarter - inch external trapezoidal thread at one end of the first drill pipe connector 13. The hollow diameter of the output end of the power rotation output part on the gas drainage hole drilling rig 11 is 3.5 - 5 mm and is connected to the hollow fluid channel with a diameter of 11 - 12.2 mm of the first drill pipe connector 13. Since the outlet of the fluid connector 6 for treating dust and gas in the gas drainage hole is connected to the hollow fluid channel with a diameter of 11 - 12.2 mm of the first drill pipe connector 13, which is connected to the trapezoidal thread of the power rotation output part fixed on the gas drainage hole drilling rig 11 through a 3.5 - 5 mm metal pipe, the trapezoidal internal thread with a diameter of 11 - 12.2 mm for the quarter - inch hollow fluid channel is used for micro - adjusting the interaction between the water particle group and the aerodynamic force through the change of its effective diameter due to the change of the thread gap. The fluid for treating dust and gas in the gas drainage hole passes through the basic fluid pressure air 1 and basic fluid pressure water 2 in the fluid generator 5 for treating dust and gas in the gas drainage hole. Through the complex interaction of tearing, pulling, dragging, pressing and friction at the contact interface, the contact interface between the water particle group and the pressurized air is modified, and the dynamic wetting ability of the fluid is enhanced, so that a dynamic gas - water atomized fluid is generated at the contact interface between the gas flow and the water particle group fluid, making it difficult to form aerosol that is difficult to treat. During drilling, the explosive mixture formed by dust and air is not easy to accumulate. And the surface physical properties of the dust change in the dynamic gas - water atomized fluid environment, and its hydrophilic property is enhanced, making it easy to combine with the modified water particles into large particles. At the same time, the modified water particle group interface polarity effect in the dynamic gas - water atomized fluid effectively adsorbs the gas, and the interface polarity effect is further enhanced on the carbon particle dust, making it easier for the gas to combine with the modified water particles into large particles. In this way, the gas changes from a gaseous state to a liquid state existing in space, and loses the possibility of explosion due to accumulation. The gas drainage drilling rig 11 is connected to the first drill pipe 8 with a fluid channel for treating dust and gas in the gas drainage hole through the first drill pipe connector 13. The fluid for treating dust and gas in the gas drainage hole is accessed through the gas drainage drilling rig 11 and the first drill pipe 8 with a fluid channel for treating dust and gas in the gas drainage hole. The second drill pipe connector 15 is 45 mm long and has an effective diameter of 11 - 12.The trapezoidal internal thread with a pitch diameter of 2 mm, whose effective diameter changes with the change of the thread clearance, is a water particle group interaction micro-regulator; the trapezoidal internal threads with a diameter of 11 - 12.2 mm for the quarter-inch hollow fluid channel are respectively connected to the trapezoidal external threads at the other end on the first drill pipe 8 with a dust and gas fluid channel for controlling gas drainage holes and the trapezoidal external threads of the hollow fluid channel with a diameter of 3.5 - 5 mm on the second drill pipe 9 with a dust and gas fluid channel for controlling gas drainage holes. The trapezoidal external threads of the hollow fluid channel with a diameter of 3.5 - 5 mm on the second anchor drill pipe 8 are connected to the trapezoidal internal threads of the drill pipe fluid nozzle and the drill bit connector 10 with a hollow fluid channel with a diameter of 1.5 - 3 mm, which has a dust and gas fluid channel for controlling gas drainage holes. The drill pipe fluid nozzle and the drill bit connector 10 with a dust and gas fluid channel for controlling gas drainage holes have a diameter of 1.The trapezoidal internal thread at the other end of the 5-3 mm hollow fluid channel is connected to the external thread of the drill pipe bit 17; and complex interactions occur at the contact interface between the gas flow and the water particle group fluid to generate a gas-water atomized fluid; the dust and gas fluid in the gas drainage hole is accessed through the gas drainage drill 11 and the first drill pipe 8 with a channel for treating the dust and gas fluid in the gas drainage hole, and the dust and gas fluid in the gas drainage hole is connected to the second drill pipe 9 with a channel for treating the dust and gas fluid in the gas drainage hole through the first drill pipe 8 with a channel for treating the dust and gas fluid in the gas drainage hole. Complex interactions occur at the contact interface between the gas flow and the water particle group fluid to generate a gas-water atomized fluid; the drill pipe fluid nozzle and bit connector 10 with a channel for treating the dust and gas fluid in the gas drainage hole is connected to the second drill pipe 9 with a channel for treating the dust and gas fluid in the gas drainage hole. The dust and gas fluid in the gas drainage hole passes through the second drill pipe 9 with a channel for treating the dust and gas fluid in the gas drainage hole and the drill pipe fluid nozzle and bit connector 10 with a channel for treating the dust and gas fluid in the gas drainage hole and is ejected from the drill pipe fluid nozzle.

The generated gas-water atomized fluid modifies the dust and condenses with the water particle fluid into large particles and is discharged together with the drilled minerals through the drill pipe spiral channel. A large amount of carbon particle dust 19 exists in the drilling operation space, and the carbon particle dust 19 strengthens the polarization interface formed at the interface between the pressure gas and the water particle group, making it easier to form the mixed solid 20 of water particles, carbon particle dust, bound gas and other dust; in this way, the dust and gas generated during the drill pipe drilling process are treated immediately, and there is no accumulation of difficult-to-treat dust aerosol and gas. The dust and gas exist in the form of liquid particles and are output as waste through the drill pipe spiral passage, and are transported away in the harmless form of the mixed solid 20 of water particles, carbon particle dust, bound gas and other dust; ensuring normal production.

[0005] Usage method of the device for treating dust and gas in the gas drainage hole by modifying the water particle group fluid: First step: The basic fluid pressure air 1 with a working pressure of 0.4 - 0.8 Mpa is introduced through the pressure air pipeline 3 with a diameter of 8 - 10 mm into the pressure air inlet on the lower left side of the fluid generator 5 for treating dust and gas in the gas drainage hole of the mine. The basic fluid pressure water 2 with a working pressure of 0.3 - 0.5 Mpa is introduced through the pressure water pipeline 4 with a diameter of 5 - 7 mm, and through the water particle group coarse adjuster 16, into the pressure water inlet on the upper left side of the fluid generator 5 for treating dust and gas in the gas drainage hole of the mine. Second step: The fluid for treating dust and gas in the gas drainage hole of the mine is introduced into the gas drainage hole drill 11 through the fluid accessor 6 for treating dust and gas in the gas drainage hole of the mine on the right side of the fluid generator 5 for treating dust and gas in the gas drainage hole of the mine. The gas drainage hole drill 11 is fixed on the drill rod fixing wall 12 of the driving roadway. The fluid accessor 6 for treating dust and gas in the gas drainage hole of the mine is fixed on the fixing plate beside the left handle on the gas drainage hole drill 11. The inlet of the fluid accessor 6 for treating dust and gas in the gas drainage hole of the mine is hermetically connected to the fluid generator 5 for treating dust and gas in the gas drainage hole of the mine on the fixing plate beside the right handle on the gas drainage hole drill 11 through a stainless steel metal pipe 7 with an inner hole diameter of 8 mm. Third step: A fluid polarity intensity ultrasonic detector 21 is vertically installed on the metal pipe with a diameter of 3.5 - 5 mm at the outlet of the fluid accessor 6 for treating dust and gas in the gas drainage hole of the mine. The fluid polarity intensity ultrasonic detector 21 feeds back the collected polarization intensity data to the water particle group coarse adjuster 16. The water particle group coarse adjuster 16 dynamically adjusts the range of the water output of the taper contact surface by adjusting the spring adjustment knob thereon, so as to provide a dynamically variable turbulent water volume for the interaction process between the pressure air and the water particle group, and control the fluid polarization intensity of the fluid generator 5 for treating dust and gas in the gas drainage hole of the mine. Fourth step: The outlet of the fluid accessor 6 for treating dust and gas in the gas drainage hole of the mine is rotationally and hermetically connected to the inlet end of the power rotation output part fixed on the gas drainage hole drill 11 through a metal pipe with a diameter of 3.5 - 5 mm. The outlet end of the power rotation output part fixed on the gas drainage hole drill 11 is a hollow outer trapezoidal thread with a diameter of 3.5 - 5 mm and a quarter-inch size. The power rotation output part fixed on the gas drainage hole drill 11 is a hollow outer trapezoidal thread with a quarter-inch size, which is connected to the external trapezoidal thread of a quarter-inch at one end of the first drill rod connector 13. Fifth step: The fluid for treating dust and gas in the gas drainage hole of the mine is introduced through the gas drainage drill 11 and the first drill rod 8 with a channel for treating dust and gas in the gas drainage hole of the mine. The fluid for treating dust and gas in the gas drainage hole of the mine is connected to the second drill rod 9 with a channel for treating dust and gas in the gas drainage hole of the mine through the first drill rod 8 with a channel for treating dust and gas in the gas drainage hole of the mine. Step 6: Connect the drill pipe fluid nozzle and the bit connector 10 with channels for treating dust and gas fluid in the gas drainage hole to the drill pipe bit 17. Step 7: Fix the gas drainage hole drilling rig 11 on the coal wall 12 of the driving roadway. Due to the influence of the driving on the original stress, during the drilling process of the drill pipe bit 17 on the gas drainage hole drilling rig 11, dust 14, gas 18, and carbon particle dust 19 generated by the drill pipe drilling are produced in the space between the bit, the rotating rod, the rotating rod connector, and the hole wall. Step 8: Treat the dust and gas fluid in the gas drainage hole. The fluid passes through the second drill pipe 9 with channels for treating dust and gas fluid in the gas drainage hole, the drill pipe fluid nozzle and the bit connector 10 with channels for treating dust and gas fluid in the gas drainage hole, and is ejected from the drill pipe fluid nozzle. The gas flow and the water particle group fluid will produce complex interaction at the contact interface to generate a gas-water atomized fluid. Step 9: The fluids ejected from the drill pipe fluid nozzle on the bit connector 10 interact to generate a gas-water atomized fluid. The generated gas-water atomized fluid modifies the dust and condenses with the water particle fluid into large particles, which are discharged together with the drilled minerals through the drill pipe spiral channel. In this way, the dust and gas generated during the drill pipe drilling process are treated immediately, and there is no accumulation of difficult-to-treat dust aerosol and gas. The dust and gas exist in the form of liquid particles and are output as waste through the drill pipe spiral passage to the junction of the gas drainage hole drilling rig 11 and the coal wall 12 of the driving roadway, and are transported away in the harmless form of a solid mixture 20 of water particles, carbon particle dust, gas, and other dust, ensuring the normal progress of production.

[0006] Step 10: As the bit drilling work progresses, the water particle group coarse adjuster 16 dynamically adjusts the range of the water output at the tapered contact surface by adjusting the spring adjustment knob on it, so as to provide a dynamically variable turbulent water volume for the interaction process between the pressurized gas and the water particle group. The basic fluid pressure air 1 and the basic fluid pressure water 2 produce complex interactions of tearing, pulling, dragging, pressing, and friction at the contact interface. The contact interface between the water particle group and the pressurized air is modified, and the dynamic wetting ability of the fluid is enhanced, resulting in the generation of a dynamic gas-water atomized fluid at the contact interface between the gas flow and the water particle group fluid. As a result, it is difficult to form aerosols, and the explosive mixture formed by dust and air during drilling is not likely to accumulate. The surface physical properties of the dust change in the dynamic gas-water atomized fluid environment, and its hydrophilic property is enhanced, making it easy to combine with the modified water particles into large particles. At the same time, the modified water particle group surface in the dynamic gas-water atomized fluid effectively adsorbs the gas, making the gas exist in a liquid state in the space and losing the possibility of explosion due to accumulation.

[0007] The advantages of the device for treating dust and gas in the gas drainage hole by modifying the water particle group fluid of the present invention are as follows: The first invention is a method that generates changes in surface tension and interfacial polarity effects through the relative movement of the interface between aerodynamic force and water particle groups, and further enhances the interfacial polarization effect in the presence of a large number of carbon dust particles, enabling the simultaneous treatment of the sources of dust and gas in the aerosolized dynamic fluid. It effectively solves the difficult-to-treat aerosol problem caused by the generation of dust and air, overcomes the accumulation of explosive mixtures formed by dust, gas, and air during drilling, and the fluid ejected from the fluid nozzle of the drill pipe interacts to generate an air-water atomized fluid. The generation of the air-water atomized fluid modifies the dust and condenses with the water particle fluid into large particles, which are discharged together with the drilled minerals through the spiral channel of the drill pipe. In this way, the dust and gas generated during the drilling process of the drill pipe are treated in the first time, without generating difficult-to-treat dust-air aerosols and gas accumulation phenomena. The dust and gas exist in the form of liquid particles and are output as waste through the spiral passage of the drill pipe, ensuring the normal progress of production.

[0008] The second invention is a device that generates changes in surface tension and interfacial polarity effects through the relative movement of the interface between aerodynamic force and water particle groups, and further enhances the interfacial polarization effect in the presence of a large number of carbon dust particles, enabling the simultaneous treatment of the sources of dust and gas in the aerosolized dynamic fluid. It effectively solves the difficult-to-treat aerosol problem caused by the generation of dust and air, overcomes the accumulation of explosive mixtures formed by dust, gas, and air during drilling. It is a device with a simple structure, convenient operation, and reliable performance that can simultaneously treat the dust pollution and gas accumulation hazards in the gas drainage holes in the first time, with obvious treatment effects and high efficiency, treating both the symptoms and the root causes, and playing a role in ensuring the safety production of mines, fundamentally solving the problem of treating the escape of dust and gas. It not only realizes the main purpose of safe production during the gas treatment process, but also solves the problem of treating the continuous escape of gas under the condition of original stress change, making gas treatment an event that can be easily achieved in our daily work and life.

First, the basic fluid pressure air 1 with a working pressure of 0.8 Mpa is connected through the pressure air pipeline 3 with a diameter of 10 mm to the pressure gas inlet on the lower left side of the fluid generator 5 for treating dust and gas in a gas drainage hole. The basic fluid pressure water 2 with a working pressure of 0.5 Mpa is connected through the pressure water pipeline 4 with a diameter of 7 mm and through the water particle group coarse adjuster 16 to the pressure water inlet on the upper left side of the fluid generator 5 for treating dust and gas in a gas drainage hole. The water particle group coarse adjuster 16 dynamically adjusts the range of the water output of the taper contact surface by adjusting the spring adjusting knob thereon, thereby providing a dynamically variable turbulent water volume for the interaction process between the pressure gas and the water particle group. The fluid for treating dust and gas in a gas drainage hole is connected to the gas drainage hole drill rig 11 through the fluid accessor 6 for dust and gas in a gas drainage hole on the right side of the fluid generator 5 for treating dust and gas in a gas drainage hole. The fluid accessor 6 for dust and gas in a gas drainage hole is fixed on the fixing plate beside the left handle on the gas drainage hole drill rig 11. The inlet of the fluid accessor 6 for dust and gas in a gas drainage hole is hermetically connected to the fluid generator 5 for treating dust and gas in a gas drainage hole fixed on the fixing plate beside the right handle on the gas drainage hole drill rig 11 through the stainless steel metal pipe 7 with an inner diameter of 8 mm. The outlet of the fluid accessor 6 for dust and gas in a gas drainage hole is rotationally and hermetically connected to the inlet end of the power rotation output part on the gas drainage hole drill rig 11 through a metal pipe with a diameter of 5 mm. A fluid polarity intensity ultrasonic detector 21 is vertically installed on the metal pipe with a diameter of 5 mm at the outlet of the fluid accessor 6 for dust and gas in a gas drainage hole. The fluid polarity intensity ultrasonic detector 21 feeds back the collected polarization intensity data to the water particle group coarse adjuster 16. The water particle group coarse adjuster 16 dynamically adjusts the range of the water output of the taper contact surface by adjusting the spring adjusting knob thereon, thereby providing a dynamically variable turbulent water volume for the interaction process between the pressure gas and the water particle group and controlling the fluid polarization intensity of the fluid generator 5 for treating dust and gas in a gas drainage hole.The outlet end of the power rotary output part fixed on the gas drainage hole drill 11 is a hollow external trapezoidal thread with a diameter of 5 mm and a quarter-inch size. The power rotary output part fixed on the gas drainage hole drill 11 is a hollow external trapezoidal thread with a quarter-inch size, which is connected to the external trapezoidal thread at one end of the first drill pipe connector 13. The hollow diameter of the output end of the power rotary output part on the gas drainage hole drill 11 is 5 mm and is connected to the hollow fluid passage with a diameter of 12.2 mm in the first drill pipe connector 13. Since the outlet of the fluid accessor 6 for treating dust and gas in the gas drainage hole is connected to the hollow fluid passage with a diameter of 12.2 mm in the hollow first drill pipe connector 13, which is connected to the trapezoidal thread of the power rotary output part fixed on the gas drainage hole drill 11 through a metal pipe with a diameter of 5 mm. The trapezoidal internal thread with a diameter of 12.2 mm for the quarter-inch hollow fluid passage is used for micro-adjusting the interaction between the water particle group and the aerodynamic force through the change of its effective diameter due to the change of the thread gap. The fluid for treating dust and gas in the gas drainage hole generates basic fluid pressure air 1 and basic fluid pressure water 2 in the fluid generator 5 for treating dust and gas in the gas drainage hole. Through the complex interaction of tearing, pulling, dragging, pressing and friction at the contact interface, the contact interface between the water particle group and the pressure air is modified, and the dynamic wetting ability of the fluid is enhanced, so that the dynamic gas-water atomized fluid is generated at the contact interface between the gas flow and the water particle group fluid, making it difficult to form aerosol that is difficult to treat. During drilling, the explosive mixture formed by dust and air is not easy to accumulate. And the surface physical properties of the dust change in the dynamic gas-water atomized fluid environment, and its hydrophilic property is enhanced, making it easy to combine with the modified water particles into large particles. At the same time, the modified water particle group interface polarity effect in the dynamic gas-water atomized fluid effectively adsorbs the gas, and the interface polarity effect is further enhanced in the carbon particle dust, making it easier for the gas to combine with the modified water particles into large particles. In this way, the gas changes from a gaseous state to a liquid state and exists in space, losing the possibility of explosion due to accumulation.

The explosive mixture formed by dust and air during drilling is not easy to accumulate. The surface physical properties of the dust change in the dynamic gas-water atomized fluid environment, and its hydrophilic property is enhanced, making it easy to combine with the modified water particles into large particles. At the same time, the modified water particle group surface in the dynamic gas-water atomized fluid effectively adsorbs the gas, so that the gas exists in a liquid form in the space and loses the possibility of explosion due to accumulation.

The outlet of the fluid accessor 6 for dust and gas in a gas drainage hole is rotationally and hermetically connected to the inlet end of the power rotation output part of the gas drainage hole drill 11 through a metal pipe with a diameter of 4 mm. A fluid polarity intensity ultrasonic detector 21 is vertically installed on the metal pipe with a diameter of 4 mm at the outlet of the fluid accessor 6 for dust and gas in a gas drainage hole. The fluid polarity intensity ultrasonic detector 21 feeds back the collected polarization intensity data to the water particle group coarse adjuster 16. The water particle group coarse adjuster 16 dynamically adjusts the range of the water output of the taper contact surface by adjusting the spring adjusting knob thereon, thereby providing a dynamically variable turbulent water volume for the interaction process between the pressure gas and the water particle group, and controlling the fluid polarization intensity of the fluid generator 5 for treating dust and gas in a gas drainage hole.The outlet end of the power rotation output part fixed on the gas drainage hole drill 11 is a hollow external trapezoidal thread with a diameter of 4 mm (1 / 4 inch).

The dust and gas exist in the form of liquid particles and are output as waste through the drill pipe spiral passage, ensuring normal production. The usage method of this device:.

Step 7: Fix the gas drainage hole drilling rig 11 on the coal wall 12 of the driving roadway.

In this way, the dust and gas generated during the drill pipe drilling process are treated immediately, and there will be no phenomenon of difficult-to-treat dust air aerosol and gas accumulation.

[0016] Step 10: As the drill bit advances in the drilling operation, the water particle group coarse adjuster 16 dynamically adjusts the range of the water output at the taper contact surface by adjusting the spring adjustment knob on it, so as to provide a dynamically variable turbulent water volume for the interaction process between the pressurized gas and the water particle group; The basic fluid pressure air 1 and the basic fluid pressure water 2 produce complex interactions of tearing, pulling, dragging, pressing and friction at the contact interface. The contact interface between the water particle group and the pressurized air is modified, and the dynamic wetting ability of the fluid is enhanced, so that the gas flow and the water particle group fluid produce a dynamic gas-water atomized fluid at the contact interface, resulting in the inability to form difficult-to-treat aerosol. The explosive mixture formed by dust and air during drilling is not easy to accumulate. The surface physical properties of the dust change in the dynamic gas-water atomized fluid environment, and its hydrophilic property is enhanced, making it easy to combine with the modified water particles into large particles. At the same time, the modified water particle group surface in the dynamic gas-water atomized fluid effectively adsorbs the gas, making the gas exist in a liquid state in the space and losing the possibility of explosion due to accumulation.
