Study on Security Appraise Method of Mining under "Three Bodies" in Mining Area

Recently year, the problem of safety mining under buildings, water bodies, and railways and highways is very serious; this paper aims at this problem, and analyses the complexity, diversity and uncertainty of mining damage, at the same time, it bases on the theory of probability and integral and the measure of computer simulation, and sets up the appraise system of mining under surface protection buildings by the main ideology of " \´mining project\´ -\´movement and deformation about overburden rock strata\´ -\´surface protection buildings\´ -\´mining damage and protection\´ ", and it has been widely applied. Practices have proved that this appraise system is strong, it is not only one of the credible methods, but it is one of the effective methods about mining industry sustainable development.
