采空区上隅角瓦斯积聚治理研究分析

摘要

Due to the comprehensive mechanized mining intensity great,production concentration,the speed of promotion quickly,a large area of goaf formed. A lot of gas gathered in the goaf and often cause gas tail-entries in working face and back to romantic (especially in the upper corner),this se-verely restrict the safety of mine production.In the paper summed up the control method of the upper corner gas which used present commonly,and real-ized drainaging goaf gas is an important way to prevent the gas of the upper corner accumulation.,and put forward using resistance curtain、auxiliary fan and drainage pipe together. The reference experience is provided for the prevention and cure of coal and gas outburst in mines.%由于综合机械化采煤开采强度大、生产集中、推进速度快，形成较大面积的采空区，从而聚集大量的瓦斯，常常造成工作面及回风流（尤其是上隅角）瓦斯超限，严重地制约了整个矿井的安全生产[1]。该文总结了目前常用的治理上隅角瓦斯的方法，并进行了分析，认识到抽采采空区瓦斯是防止上隅角瓦斯积聚的一个重要途径，并且提出挡风帘与局部通风机、抽排管配合使用，从而为防止瓦斯超限提供借鉴经验。
