摘要
钻井水溶法开采流程简单、操作方便、劳动负荷轻、投资少、见效快,是一种很有发展前途的采矿方法。钻井水溶法开采形成的地下采空区可能会使地表发生移动和变形。随机介质预计理论概率积分法是建立在上履岩层软弱、顶板跨落基础上的非连续介质理论。由于沉积成矿的特点,岩盐矿床的地质条件决定了其岩石力学性质整体表现为顶、底板强度较低,适应于采用随机介质理论预计地表移动与变形。文章结合某钻井水溶法开采矿山实例,探讨地表移动与变形预计随机介质预计方法。
The drilling solution mining is a sort of growth potential method of mining, which has simple process; convenient operation; light labor load; less investment and faster effect. The underground Mined- out areas, which are formed by drilling solution mining, may make the ground surface deformation and movements. Probability integration method of stochastic media expectation theory, which bases on the foundation of flaccid up-cover terrane and bestraddle of top board,is discontinuous media theory. As the character of sediment turning into ore-forming material, the mechanics character of rock wholly behaves lower intenseness on top and bottom board, which is decided by geologic condition of salt deposit, it is adapt to use stochastic media theory to expect ground surface deformation and movements. This paper combines a certain example of mining mine by drilling solution to discuss the method of expectation of ground surface deformation and movements to expectation of stochastic media theory.
