摘要
对炉峪口煤矿近距离8#、9#煤层采用下行式开采时,通过理论分析、数值模拟等手段着重分析位于上部8#煤层采空区下方不同位置处的9#煤层巷道应力、塑性分布及位移变化等情况,从而为在下行式开采时对下部巷道的布置方法及支护方案的探究提供理论基础,也为本矿9#煤层中的巷道参数及支护设计提供参考和指导依据。
When Luyukou close 8 # 9 # coal seam mining Descending through theoretical analysis, numerical simulation and other means in the upper part focuses on Coal Seam 8 # 9 # coal seam tunnel beneath stress at different locations, plastic distribution and displacement, etc., in order to provide a theoretical basis for the exploration of the lower portion of the roadway layout method and support scheme in the downlink exploitation of, also based mine roadway 9 seam parameters and support designed to provide reference and guidance in accordance with.
