Surface movement predicting problems of deep strip pillar mining

Based on the model of probability integral method,the current calculating methods of predicting perimeters and their predicted results were studied through a typical case.The problems of these methods and their advantages and disadvantages were discussed when they were used to predict surface movement and deformation of deep strip mining.The results demonstrate that the results of all of these methods cannot describe perfectly the surface movement and deformation of deep strip pillar mining.The method combined by equations(3) in this paper and multi-face predicting method using full extraction parameters was put forward.This method can predict the surface movement and deformation of deep strip pillar mining accurately.
