摘要
论文根据现场工程地质条件、室内试验以及理论分析,对常村煤矿2 1盘区延深胶带下山变坡点附近巷道支护现状和破坏特点进行分析研究,总结破坏原因。通过现场调查和巷道破坏特点,确定软岩变形力学机制,并提出支护对策。
Base on the geological conditions of the project,labor test and theoretical analysis,the paper had an analysis and study on the roadway support status and failed features near the ramp of the extended belt conveyor dip entry in No1 mining area of Changcun Mine.The failure causes were summarized.According to the site investigation and the failure features of the mine roadway,the mechanic mechanism of the soft rock deformation was confirmed.The paper provided the countermeasures for the roadway support.
