Abstract

The invention discloses an explosion-proof airtight airbag for a coal mine roadway, which comprises a hydrogel coagulation bag arranged in sequence from front to back, an arc-shaped stress plate, a first airtight airbag, a disc-shaped baffle, a second airtight airbag and a disc Shaped baffle, the arc-shaped stress plate, the first airtight airbag, the disc-shaped baffle, the second airtight airbag and the inner center of the disc-shaped baffle are all connected together by a through composite pipeline and The front of the composite pipeline is connected and fixed with the hydrogel coagulation bag, the disc-shaped baffle is arranged vertically and is surrounded by three supporting telescopic rods distributed in the shape of an equilateral triangle, and the rear end of the composite pipeline is The V-shaped bracket is used to support the sleeve inside the transition sleeve. The airbag structure combines the advantages of explosion-proof equipment in the prior art, and the installation time is shorter than traditional airtight explosion-proof equipment, and can achieve better explosion-proof and airtight effects to ensure the safety of underground construction.

Description

technical field [0001] The invention relates to the technical field of underground explosion-proof safety equipment, and more specifically, relates to an explosion-proof airtight air bag for a coal mine roadway. Background technique [0002] The underground production conditions of my country's coal mines are complex and the geological conditions are changeable. Among the more than 26,000 coal mines, about 50% are high-gas mines, and 60% to 70% are mined under complex and extremely complex structural conditions. The deepening and expansion of the area is often threatened by disasters such as water, fire, gas, coal dust, roof, etc., and the consequences of the disaster are relatively serious, and the security situation is very severe. Especially gas explosion accidents, while causing huge economic losses, have also brought serious casualties, bringing misfortune to many families of miners. According to the national coal mine accident statistics from 2002 to 2003, gas accident...
