摘要
分析了曙光煤矿2207胶带运输顺槽巷道的支护形式、参数,以及存在的片帮严重、工程进度缓慢、劳动强度大等问题,通过计算与COMSOL软件模拟确定了巷道围岩破坏深度,优化了支护参数。
Taking 2207 working face in Shuguang Colliery as the object of study, the paper points out the existing problems of serious rib fall, slow construction progress and large labor intensity by analyzing the original support pattern and parameters, and proposes the support optimization according to the crushing depth of roadway surrounding rock determined by calculation and COMSOL software simulation, which can not only improve the support effect but also reduce the labor intensity with high efficiency.
