摘要
为安全有效地进行上行开采,根据华坪县思棉煤矿煤层赋存条件及开采现状,利用理论分析和数值模拟对其进行分析验证,研究其上行开采顶板的围岩运动规律,通过工程实践证明思棉煤矿上行开采经济上合理,技术上可行。
In order to ensure the security of ascending mining,this paper analyze and verify the move-ment rules of surrounding rocks while mining based on the related theories and numerical simulation ac-cording to the present mining situation and occurrence of coal seam of Si Mian Mining area in Hua Ping County.Finally practice proves that ascending mining in Si Mian coal area is reasonable in economy and techniques is feasible,which could provide reference for similar mines.
