【摘要】 使用FLAC软件预测出采空区形成后引起的地表垂直和水平位移,然后使用数值分析方法,计算出地表各个沉降点的斜率和曲率,预测结果对矿山建设有参考作用。更多还原

【Abstract】 The surface vertical and horizontal displacements resulted from the mined-out pit are predicted by use of the FLAC software and the slope and curvature of surface sedimentation at every locus are figured out with numerical value analysis theory. The prediction results can be referred for the mine construction.更多还原
