采空区上隅角瓦斯积聚治理研究分析OA
Controlling、researching and analyzing the goaf upper corner gas accumulation
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。
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…查看全部>>
