胡底煤矿开拓大巷层位选择设计研究

Study on Stratohorizon Selection Design of Development Roadway in Hudi Mine

随着开采深度的增大,煤与瓦斯突出矿井在晋城矿区日益增多,防治煤与瓦斯突出在矿井建设和生产中是安全工作的重中之重,而减少井巷工程揭煤是预防煤与瓦斯突出最直接有效的方法。文章针对胡底煤矿煤层赋存情况,对其井筒落底及开拓大巷层位选择进行了设计研究。

With the increasing of mining depth, coal and gas outburst accidents increased in Jincheng mining area, coal and gas outburst prevention in the construction and production of coal mine was the priority among priorities of the security work, and reducing the frequency of shaft and roadway coal uncovering was the most direct and effective prevention method of coal and gas outburst. According to the occurrence of coal seams in Hudi coal mine, the horizons of shaft bottom and main development roadway were selected.
