摘要
本文以山西吕梁店坪煤矿5-200工作面110工法切顶卸压沿空留巷无煤柱开采为工程案例,研究了留巷期间巷道三区临时支护工艺,现场工程效果较好,对同地质条件下煤矿沿空留巷临时支护具有借鉴意义。
This paper taking the engineering case of coal pillar mining in Dianping Coal, as an example studied the temporary support technology alone the remained lanes in zone 3, the on-site engineering effect of the technology is good, and it is also of great significance to the coal-mining works in the same geological conditions.
