摘要
煤矿开采过程中对于顶板岩层、主采煤层、煤层底板岩层都具备较软性质时就可以将其称为是"三软"煤层,此类煤层是软弱岩层煤层裂隙发育,整体构造相对复杂,论文对"三软"煤层巷道掘进过程中所存在的问题以及该如何保证掘进效率和掘进安全进行分析。
In the process of coal mining,it can be called"three soft"coal seam when the roof strata,the main mining coal seam and the coal seam floor rock have soft properties,this kind of coal seam is the development of coal seam fissures in weak rock seam,and the whole structure is relatively complex,In this paper,the problems existing in the roadway excavation process in the"three soft"coal seam and how to ensure the efficiency and safety of tunneling are analyzed.
