Analysis on Affecting Factors of Controlling Surface Subsidence of Filling Mining

It is mining subsidence that causes the damage of ecological environment and the surface buildings. The basic method to relieve the damage is to controll surface subsidence effetely. For this problem, the thesis studied the characteristics of overlying rock failure through theoretical analysis, on the basis of the mechanism of surface subsidence. Then we obtained three main factors to subsidence which are sunken, compression, and lithological characters. According to the main factors influencing mining subsidence under cut and fill mining, then we reduce the impact from these factors successfully by taking appropriate measures to control it.
