摘　　要：文中根据空间等效效应,利用随机介质理论证明了下沉系数与地表沉陷体积和开采空间体积比之间的等效关系,研究了下沉系数的近似计算方法,并进行了实例分析。结果表明:在无实测资料情况下,本文方法能够满足工程应用。According to the rule of space equivalence, the equivalent relationship between the subsidence coefficient and the volume ratio is proved with the theory of stochastic medium. Then, the approximate calculation method of subsidence coefficient is given and used in the example. The result shows that the method in this paper can satisfy the engineering application when there is no measured data.
