煤矿回采巷道支护优化实践分析

Analysis of Optimisation Practice of Tunnel Support in Coal Mine Back to Mine

以某煤矿10号煤层1031003工作面为研究对象,介绍一种回采巷道支护优化方案,包括主辅运顺槽优化方案、主回撤通道优化方案、切眼支护方案三部分内容。为检验优化方案的应用价值,采用数值仿真模拟方法对比原方案和优化方案,并在初步确认优化方案的应用价值后,将优化方案应用于工程实践,最终确认优化方案可满足工作面巷道支护要求。

Taking 1031003 working face of No.10 coal seam in a coal mine as an example,a kind of optimisation scheme for back-mining roadway support is introduced,which includes three parts,namely,optimisation scheme for main and auxiliary transport runway,optimisation scheme for main withdrawing channel,and support scheme for cutting eye.In order to test the application value of the optimisation scheme,numerical simulation is used to compare the original scheme and the optimisation scheme,and after preliminary confirmation of the application value of the optimisation scheme,the optimisation scheme is applied in engineering practice,and it is finally confirmed that the optimisation scheme can meet the requirements of the roadway support of the working face.
