文摘Using FLAC3D numerical simulation software,the influence laws that the different mining depth,mining width and filling step have on the surface subsidence and horizontal movement under the condition of filling mining has been studied.The functional relation among full subsidence and horizontal movement of surface,mining depth,mining width and filling step has been given,which provides theoretical formulas been referenced for filling mining theory and has a certain guiding value.
