摘要
Abstract
A coal mine 42 mining area substation affected by the fault zone tectonic stress and the multiple dynamic pressure nearby mining area and the high abutment pressure from the permanent coal pillar, its deformation is serious, after several renovations and reinforcement, has been used so far. However, with the advance of the 42 working face, it is bound to have a greater dynamic impact. According to the original roadway supporting form and deformation characteristics, the reasons of the roadway deformation were analyzed, the supporting scheme was designed, the ifeld test results indicate that the roadway support effect is good, can effectively control the deformation of surrounding rock.关键词
