摘要
以斜沟矿23101综放工作面为工程背景,研究残煤回采巷道的矿山压力,同时采用FLAC 3D数值模拟软件分析了工作面推进距离对巷道围岩应力分布、顶底板移动量、工作面两帮移动量的影响,为残煤回采巷道的矿压分析及支架选型提供参考。
Taking the 23101 fully-mechanized top-coal cavin g face of the inclined ditch as the engineering background,the mining pressure of the residual coal mining tunnel is studied,and the influence of the advancing distance of the working face on the stress distribution of the surrounding rock,the moving amount of the top plate and the moving amount of the working face is analyzed by using the FLAC 3 D numerical simulation software.It provides a reference for the analysis of the mine pressure and the selection of the support for the residual coal.
