Description

Technical Field

[0001] The present invention relates to the field of mine safety and is suitable for controlling harmful dust generated during mining operations. It uses aerosolized dynamic fluid to control dust pollution in anchor support drilling during tunneling, providing a simple, easy-to-operate, and reliable device for source-directed control of dust pollution. Background Art

[0002] As we all know, the mining of coal and rock seams causes changes in mine pressure, necessitating the use of anchor bolts to support these seams and rock formations during tunneling to ensure safety and stability. However, due to the short drilling time and high drilling quality requirements of anchor bolting, as well as the complex mining and geological conditions of coal and rock seams, the drilling process faces challenges such as severe and difficult-to-control dust concentrations. On-site workers often work in an environment of dust, air, and water, posing a serious threat to their health and safety. The application number is CN202321840515.3, a new type of hydraulic anchor drilling vehicle for coal mines, which discloses a new type of hydraulic anchor drilling vehicle for coal mines, including a hydraulic anchor drilling vehicle body, two sets of mechanical arms, two sets of connecting plates and two sets of drilling components. The two sets of mechanical arms are symmetrically installed at the front and rear ends of the hydraulic anchor drilling vehicle body. The mechanical arms are used to adjust the position and angle of the connecting plates and the drilling components, and the connecting plates are installed on the mechanical arms, and the drilling components are installed on the connecting plates. The drilling components are used to drill holes in coal mine tunnels. It also includes a dust suction mechanism and two sets of dust hoods. The dust suction mechanism is installed on the top of the hydraulic anchor drilling vehicle body. The dust suction mechanism is used to absorb dust generated when the drilling components drill holes, and the dust hood is connected to the dust suction mechanism. The utility model prevents a large amount of dust from spreading into coal mine tunnels, causing air pollution, and also prevents explosions caused by excessive dust in the coal mine tunnels, thereby improving the safety and environmental friendliness of the device. However, it is obvious that the adsorption mechanism cannot effectively adsorb the gushing dust, which is its fatal drawback, and can only alleviate the possibility of pollution and explosion. Application No. CN202321083802.4, a patent for a dust removal device for a handheld anchor drill for mining, discloses a dust removal device for a handheld anchor drill for mining, which is provided with a steel casing, and a section of elastic rubber hose is connected to the upper end of the steel casing by a clamp to form a three-way pipe sleeve. The three-way pipe sleeve has the top opening of the elastic rubber hose as port one, the center hole on the bottom end plate of the steel casing as port two, and the side opening of the steel casing as port three. Port one abuts the tunnel roof where the hole is located, sealing the hole in the elastic rubber hose. Port two has a built-in bearing for supporting the drill rod. Port three is connected to a wet dust collector through a conduit, and dust removal for the handheld anchor drill for mining is achieved by using the wet dust collector.The utility model adopts dry drilling to ensure drilling efficiency and uses wet dust removal to solve dust pollution. It has some effect, but the effect is limited and still cannot solve the prominent pollution and explosion hazards; the application number is CN202321345270.7 A hydraulic anchor drilling vehicle for coal mines, characterized in that it includes a mounting base, a dust treatment component is provided inside the mounting base, one side of the dust treatment component is connected to the drilling component, and a moving component is provided at the bottom of the mounting base; the dust treatment component includes a dust suction mounting frame, the dust suction mounting frame is symmetrically installed above the mounting base, a suction hood is installed inside the dust suction mounting frame, an impurity filter is installed inside the suction hood, one end of the suction hood is connected to a dust suction pipe, one side of the dust suction pipe is connected to a dust suction fan, one end of the dust suction fan is connected to a dust exhaust pipe, and one side of the dust exhaust pipe is connected to a dust treatment water tank. This technology has some effect on dust control, but dust pollution and explosion risks still exist.

[0003] All of the above technologies occupy valuable drilling operation space and absorb dust for control while the drill rod discharges the drilled object, or wet the object externally to achieve the purpose of control. Although some weaknesses of the existing water jet drill rod drilling dust control are avoided, the dilemma of drilling work not working in an artificial mudslide state is improved to a certain extent, but the problem of dust control in the drilling operation space cannot be effectively solved. These technologies of first polluting and then controlling cannot overcome the contradiction between the strong extrusion effect of high-concentration dust and the poor ability to inhale dust or humidify dust. The existing technologies cannot effectively control dust from the source. Mechanical dynamic pressure water injection into the borehole, or remedial dust control efforts after pollution, increase the labor intensity of workers, are not easy to operate, and cause secondary pollution in the operation. They can neither solve the problem of dust and air easily generating difficult-to-control aerosols. In particular, the dust suction or humidification control technology at the outlet cannot overcome the safety problem of explosive mixtures formed by dust and air during drilling. The fact that these dust removal technologies are powerless against dust that has combined with air to form aerosols shows that not only will pollution continue but also the risk of explosion is accumulating. A new source-effective dust control technology must be introduced to meet the actual needs of dust removal. Summary of the Invention

The fluid for controlling the dust in the anchor support drilling hole is generated by the basic fluid pressure air 1 and the basic fluid pressure water 2 in the anchor support drilling hole dust control fluid generator 5. 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 gas flow and the water particle group fluid generate a dynamic gas-water atomized fluid at the contact interface, making it impossible to form aerosols that are difficult to control. The explosive mixture formed by dust and air during drilling is not easy to accumulate, but the surface physical properties of dust change in the dynamic gas-water atomized fluid environment, the hydrophilic property is enhanced, and it is easy to combine with modified water particles to form large particles; the anchor drill rig 11 is connected to the first anchor drill rod 7 with a fluid channel for controlling anchor support drilling dust through the first anchor connector 13, and the fluid for controlling anchor support drilling dust is connected to the first anchor drill rod 7 with a fluid channel for controlling anchor support drilling dust through the anchor drill rig 11. The second anchor connector 15 is a trapezoidal internal thread with a length of 45 mm and an effective diameter of 11-12.2 mm.

The anchor drill bit 10 operates on the anchor fixed wall 12 of the excavation tunnel, generating dust 14 generated by the anchor drilling. The dust 14 generated by the anchor drilling is interacted with the fluid ejected from the anchor fluid nozzle on the drill bit connector 9, which generates an air-water atomized fluid. The generated air-water atomized fluid modifies the dust, condenses it with the water particle fluid, and is discharged from the drill pipe spiral flow channel along with the drilled minerals. This immediately controls the dust generated during the anchor drilling process, preventing the generation of difficult-to-control dust aerosols, and ensuring normal production.
