The study on forecast for ground subside nce at mine

The empty area ground's subsidence which be caused by exploration engineering on mineral layer is the widespread environmental engineering geologic problem. Subsidence is the direct source of geological disaster; this text makes use of the data of mine and mathematic method of trigonometric function to forecast the possible scope of ground subsiding area. The results indicate that this method can get the position and area of subsiding area and it provides scientific according for the reclamation and sufficient management of mine, and it is useful to realize the goal "who be subjected to benefits, who manages".
