摘要
针对深部软岩巷道围岩变形量大,支护困难的问题,以袁店一井煤矿103采区轨道巷为工程背景,采用实验室试验、力学理论分析、FLAC数值模拟计算分析及现场实测分析等综合研究方法,对围岩变形破坏机理及其控制深入研究,并提出最优支护方案。
For the problem of large deformation and supporting ,taking roadway of 103 mining area of Yuandian No.1 coal mine as engineering background,studied the deformation mechanism and supporting technology of soft rock roadway in depth. Synthesis analysis methods such as laboratory tests,mechanics analysis, FLAC numerical simulation and field test were used.
