Abstract By using the 3D solid-flow coupling simulation experiment equipment，the law of stress，displacement of coal floor of Dongshan Colliery in Taiyuan，during mining above aquifer is studied. A series of breaking down phenomena of coal floor is explained，and the influence factor on active coal floor summarized. The theoretical reference is provided for the study of the movement of the earth surface due to the mining.
