摘要
基于群力煤矿首采面瓦斯治理时间长,巷道工程量大,矿井达产搬家次数多等问题,通过对首采工作面保护层开采区域防突措施、井巷工程量和工作面推进度等方面进行分析与研究,优化首采工作面设计,有效减少井巷工程量,缩短工期,减少初期投资,更有利于矿井尽快投产和安全生产。
Aiming at the problems such as long period of gas treatment,large amount of roadway engineering,and frequent relocation of mine in first mining face,Qunli Colliery,the paper has analyzed and researched the protection layer mining of the first mining face,regional outburst prevention measures,the amount of roadway engineering,and the advancement of the working face,and determined the optimal first mining face,which effectively reduced the amount of roadway engineering,shortened the construction period,reduced the initial investment,and was more helpful to the safety production of the mine.
