摘要
山区采动滑移是在山区复杂的地形、地质及采矿条件下多种影响因素的综合结果 ,用有限元法从岩石力学角度出发研究采动地表和岩层内部的移动与变形的力学机制。选取了 4个山区典型地貌 ,在整个采动覆岩至地表的全断面上进行力学模拟分析 ,并与实测资料分析对比 ,着重研究了山区表土层采动滑移的特点 。
The surface movement is a comprehensive result influenced by many factors, such as topographical , geological and mining condition etc. According to rock mechanics, the finite element method(FEM) can be used to study the mechanical character of overburden and bedrock. Four typical mountainous physiognomies are selected, and the geomechanical and mining slip-paging character of whole mining section plane is analyzed. At the same time, by comparing with observed data, a slip paging rule of overburden is summzedup.
