A multi-functional integrated inflatable air bag device for gas plugging, drainage and pressure relief in goaf

Abstract

The invention relates to a multifunctional integrated inflatable air bag device for gas plugging, extraction and pressure relief in a goaf, including an air bag plugging system, a catheter drainage system, an air bag inflation and pressurization system, and a gas extraction and gas collection system; the air bag plugging system Surrounding the outside of the catheter drainage system, it is connected to the catheter drainage system through a ferrule; the end of the catheter drainage system far away from the goaf, that is, the tail, is connected to the air bag inflation and pressurization system through an external leather tube; the gas collection system is located at the end of the catheter drainage system The front of the port, that is, the front of the tail, is connected from the side by an external leather tube. The invention makes the upper corner gas treatment more effective, stable and precise, and effectively solves the problems of buried pipe, suspended pipe drainage pipe Louis damage, low air tightness of drilling drainage, and gas accumulation in the upper corner of the mining working face, and solves the problems of To a certain extent, it solves the problem of air leakage in the goaf, and provides good technical support and safety measures for the safe and efficient mining of coal resources.

Description

technical field [0001] The invention relates to a multifunctional integrated inflatable airbag device for gas plugging, drainage and pressure relief in a goaf, belonging to the technical field of coal mining. Background technique [0002] With the transformation and upgrading of the national economy and the profound adjustment of the energy structure, large-scale (super-large) coal mines occupy a dominant position in my country's coal production. With the increase of coal residue, the amount of gas emission in the working face has increased significantly, and the gas concentration in the upper corner has increased abnormally. The problem of "low gas occurrence and large gas emission" in the mine poses a huge threat to the life safety of underground workers. [0003] The gas in the coal mining face mainly comes from the gas gushing out of the goaf, accounting for about 40%-60% of the gas in the working face. And at present, our country mainly adopts U-shaped ventilation syste...
