为解决多煤层回采煤柱护巷巷道的变形破坏问题,以南阳坡矿两个相邻回采工作面为研究对象,在确定煤柱宽度和错开距离的基础上,采用现场监测、理论分析和数值模拟等研究方法,确定出煤柱的合理留设尺寸和巷道支护方法,并最终确定多煤层煤柱的布置方案.研究结果表明:该方法能够有效的控制巷道围岩变形,巷道变形短期内即趋于平稳,且支护成本低,煤柱稳定性好. In order to solve the problem of deformation and failure of roadways in coal pillar protection roadway with multi-coal seam mining, taking two adjacent mining face of Nanyangpo Mine as the research object, on the basis of determining the pillar width and the offset distance, the on-site monitoring, theoretical analysis and Numerical simulation and other research methods to determine the reasonable size of coal pillar left and roadway support methods and ultimately determine the layout of coal pillar more than the coal.The results show that this method can effectively control the roadway surrounding rock deformation, Within that tends to be stable, and support low cost, coal pillar stability.
