Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] Such as Figure 1-6 As shown, the components of the device of the present invention include an air bag blocking system 1, a catheter drainage system 2, an air bag inflation pressurization system 3 and a gas extraction and gas collection system 4; the air bag blocking system 1 surrounds the outside of the catheter drainage system 2, and passes The hoop 8 is connected with the catheter drainage system 2; the end of the catheter drainage system 2 is far away from the goaf, that is, the tail is connected with the airbag inflation pressurization system 3 through an external leather tube; the gas extraction and collection system 4 is in front of the port of the catheter drainage system 2. The tail is connected from side to side through an external leather tube.

[0038] Such as figure 1 , 6 As shown, the airbag blocking system 1 is made of stretch...

Abstract

The invention relates to a goaf gas plugging extraction and pressure relief multifunctional integrated inflatable airbag device. The goaf gas plugging extraction and pressure relief multifunctional integrated inflatable airbag device comprises an airbag plugging system, a guide pipe drainage system, an airbag inflation pressurization system and a gas extraction and collection system, wherein the airbag plugging system surrounds the outer side of the guide pipe drainage system and is connected with the guide pipe drainage system through a hoop; the end, away from a goaf, of the guide pipe drainage system, namely the tail, is connected with the airbag inflation pressurization system through an external leather hose; and the gas extraction and collection system is connected with the external leather hose from the side in front of a port of the guide pipe drainage system, namely in front of the tail. By means of the goaf gas plugging extraction and pressure relief multifunctional integrated inflatable airbag device, upper corner gas treatment is more effective, stable and more accurate, the problems that buried pipe and suspended pipe extraction pipelines are prone to damage, the drilling extraction airtightness is low, and gas is accumulated at the upper corner of a stope face are effectively solved, the problem of goaf air leakage is solved to a certain degree, and good technical guarantees and safety measures are provided for safe and efficient coal resource mining.

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...
