Technical Field

[0001] The invention discloses a method for using a multi-component composite dust removal device for underground mine tunnels, and belongs to the field of dust control in underground mine tunnels. Specifically, the invention relates to a method for using a device that generates surface tension changes and interface polarity effects through relative motion between aerodynamic forces and the interface of a water particle group, so that a constantly changing and moving water particle group occupies a limited space in the tunnel, and dust in the tunnel cannot have a drilling effect, thereby realizing a multi-component composite control of dust in the tunnel by aerosolized dynamic fluid. The device has a simple structure, is easy to operate, and has reliable performance. The key is that the dynamic fluid can effectively overcome the drilling effect of an aerosol formed by the combination of dust and gas, thereby enabling flexible and dynamic dust to be controlled. Background Art

[0002] With the popularization of mechanization in coal mining underground, the efficiency of mining and recovery has been improved, and the hazards of dust generated have also increased. In order to reduce dust dispersion, nozzles are installed on the heads of comprehensive mining equipment and comprehensive mining machines. However, the current nozzle dust removal technology on the heads of comprehensive mining machines has the problem of uneven water mist formed by high-pressure nozzles, which is easy to affect the dust removal effect and also cause water accumulation in the tunnel; dust enters the large tunnel with the wind flow, so that a large amount of suspended dust is often generated in the working tunnels of the mine. Dust and air condense and easily combine to form aerosols. Aerosols obtain enough kinetic energy with the wind flow, so it is difficult to control, which makes workers' vision blurred and visibility low when walking or working in it, which is easy to cause safety accidents; in addition, if workers inhale dust for a long time, they are prone to pneumoconiosis, which causes great harm to the physical and mental health of employees. Application No. CN202311342715.0 A dust removal and filtration device for underground tunnels in metal mines and a method of using the same; the main body of the invention has a shell mechanism fixedly connected to one side of the outer wall of the main body, a water source conveying mechanism fixedly connected to the outer wall of the shell mechanism, and a purification mechanism fixedly connected to the outer wall of the shell mechanism. Through the joint action of the main body, the shell mechanism, the water source conveying mechanism and the purification mechanism, the dust generated during the mining process is effectively adsorbed and then transported for treatment.
