| Abstract: | By using numerical simulation method,this paper mainly analyzes different mining depths and different loosen thickness of the effect on the residual sinking value and the movement and deformation value of earth's surface,and inquires into the regulation of the movement and deformation value of earth's surface.The testing results show that the residual sinking value and the movement and deformation value of earth's surface becomes smaller with the increment of mining depths and bigger with the increment of loosen thickness. |
