| 摘 要： | 露天矿山边坡岩土体疏水所引起的地表沉降及变形，往往大于开挖本身引起的沉降及变形．应用随机介质理论，假设岩土移动过程符合Ｍａｒｋｏｖ过程，再利用叠加原理，导出了露天开挖及岩土疏水导致的地表沉降及变形计算方法．计算获得的疏水导致的地表移动大小及范围均大于开挖引起的地表移动大小及范围．分析计算结果与Ｍｏｒｗｅｌ露天褐煤矿的监测资料的对比令人满意．

| Abstract: | Surface subsidence and deformation cased by dewatering in open pit mine is always more serious than that of excavation. By using stochastic medium theory, and suppose that surface movement process has the property of Markov process, by using superposition principle, the calculation method of surface subsidence and deformation caused by open pit mining and dewatering is derived. The scale and range of surface movement calculated caused by dewatering are larger than that caused by mining. It is satisfied compared the calculated results with the monitored information conducted in Morwell Open Pit Mine. |
