Three-proof device in drilling process

Abstract

The invention relates to the technical field of coal mine safety production, and specifically relates to a three-proof device in the drilling process. The three-proof device comprises a drainage conduit, a gas-water separating deslagging tank, and a gas filtering water tank, wherein one end of the drainage conduit is a slag inlet, and the other end is communicated with a drilling machine cooling water, the lower part of the drainage conduit is communicated with the gas-water separating deslagging tank, the gas-water separating deslagging tank is communicated with the gas filtering water tank, the lower part of the gas-water separating deslagging tank is provided with a water-slag discharging part, the lower part of the gas filtering water tank is provided with a drain pipe with a valve, the top end of the gas filtering water tank is provided with a negative pressure drainage nozzle stub, and the negative pressure drainage nozzle stub is connected with a mine branch duct drainage system. The gas-proof, the dust-proof and fire-proof functions of the drilling hole are integrated so as to improve the security and reliability of the mine underground operation and lay the foundation for the safety development of the mine and the harmonious the mine area construction.

Description

technical field [0001] The invention relates to the technical field of coal mine safety production, in particular to a three-proof device in the drilling process, that is, an anti-gas, dust-proof and fire-proof device used in the drilling process of anti-surprise teams in mines. Background technique [0002] The three defenses in the coal mine production process refer to the general term of gas prevention, dust prevention and fire prevention. In the process of coal mine production, gas with methane as the main component will be gushed out along with coal and rock. Gas is diffusible and suffocating, as well as flammable and explosive. Protruding with gas, causing serious damage; dust prevention refers to the technology of reducing dust concentration in coal mines and preventing coal dust explosion. There are many methods for coal mine dust prevention and dust reduction, such as comprehensive use of coal water injection, mining dust prevention, ventilation Dust removal, spray...

AI Technical Summary

Problems solved by technology

However, there are many defects in setting up anti-gas, dust-proof and fire-proof equipment separately, and some coal seams with serious protruding dangers cannot use hydraulic slagging for drilling construction, and only wind slagging can be used for drilling construction. Dust protection is especially important

For example, there are too many types of equipment, the wiring of the working face is complicated, and the operation of each equipment needs to consume more power, etc. Therefore, it is necessary to design a new type of device that integrates the three defense functions during the drilling process.
