青东矿松散围岩条件下巷道支护技术研究

East Green Mineral Loose Surrounding Rock Roadway Supporting Technology Research

青东矿井地质条件复杂,断层多,巷道围岩条件较差,巷道支护困难,给矿井安全带来威胁。本文详细阐述了104轨道大巷、石门在复杂条件下巷道综合治理支护方案及支护参数,有效控制了巷道变形量,满足了通风、行人、运输安全,降低了维护费用,节约了成本,同时为今后类似条件下的巷道支护提供了宝贵的经验。

Green East Mine with complicated geological conditions,many faults,poor rock conditions of the roadway,roadway support difficulty,to mine safety threat.This paper describes in detail the 104 track tunnel under complex conditions,Shimen in the comprehensive management of roadway supporting scheme and supporting parameter,effective control of the roadway deformation,satisfy the ventilation,pedestrians,transport safety,reduce maintenance costs,saving the cost,at the same time for future similar conditions of roadway support provides valuable experience.
