煤矿双工作面均压通风防灭火技术研究

Study on Pressure-equalizing Ventilation and Fire-extinguishing Technology in Double Working Faces of Coal Mines

均压通风技术是一种行之有效的矿井防灭火技术,加强对相关技术的探究对矿井生产的持续开展有积极意义。以此为着手点,对煤矿双工作面均压通风防灭火技术开展探究,结合工程实际,在分析回采面CO超限及其原因的基础上,探究了双工作面均压通风系统应用,并分析了其应用效果,希望能为其他矿井相似工程的开展提供借鉴与参考。

Pressure-equalizing ventilation technology is an effective mine fire prevention and extinguishing technology. Strengthening the exploration of related technologies is of positive significance to the sustainable development of mine production. Taking this as a starting point, this paper explored the technology of pressure-equalizing ventilation, fire prevention and extinguishing in double working faces of coal mines, explored the application of pressure-equalizing ventilation system in double working faces combining with engineering practice and based on the analysis of CO over-limit and its causes, and analyzed its application effect, hoping to provide reference for the development of similar projects in other mines.
