摘要
当前矿井普遍存在小窑采空区边界附近开拓掘进问题。本文结合锦界煤矿31煤一盘区集中巷二段掘进情况,总结了小窑边界附近及揭露断层时安全掘进经验,可为煤矿边界附近地质情况不明条件下的安全掘进提供借鉴。
At present, opening driving problem widely existed in small kiln goaf boundary of mine. This paper summarizes the safe tun- neling experience combining the tunneling situation of two-stage process, Jizhong Lane, 31 Coal First Panel, Jinjie Coal Mine, which may provide reference for safe tunneling under unknown geological conditions near coal mine boundary.
