The regularity and parameters of surface movement in strip mining under thick soil layer own their wellmarked characteristic. Whether or not is it accurate that the result of surface movement is predicted by use of probability integral method,the key lies in the parameters of surface movement. The thick soil layer exists in Jiaozuo coal mine. The mathematical method to analyze the regularity and parameter of surface movement in strip mining under thick soil layer on the basis of practical research data in strip mining has been used. Consequently, the function between the parameters of surface movement and the geology and coal mining condition is found.
