摘要
针对胜利东二号露天煤矿采场南帮出现变形裂隙,为准确预测边坡潜在滑移模式,利用详尽地质条件信息,进行 3Dmine-Rhino耦合建模,建立了南帮非均质真三维数值模拟模型;采用FLAC3D软件进行计算,研究了南帮潜在滑移模式.结果表明:现状地表裂隙和底鼓位置与数值模拟结果基本一致,验证了该模拟的准确性;南帮潜在滑体破坏模式为以第三系底板为弱层的圆弧-弱层组合滑动,地表裂隙和底鼓位置均会向西发展.
Abstract
Aiming at the deformation cracks appearing on the south slope of the stope in Shengli East No.2 Open-pit Coal Mine,in order to accurately predict the potential slip mode of slope,the article carries out 3Dmine-Rhino coupling modeling using detailed geological condition information,establishes the heterogeneous true three-dimensional numerical simulation model of the south slope.The article studies the potential slip mode of the south slope using FLAC3D software for calculation.The results show that the current position of surface cracks and floor heave is basically consistent with the numerical simulation results,which verifies the accuracy of the simulation;the failure mode of the potential sliding body in the south slope is the circular-weak combined sliding with the Tertiary floor as the weak layer and the location of surface cracks and floor heave will develop to the west.
