摘　　要：巨厚松散层下条带开采引起的地表移动规律及地表移动参数有明显的特点 ,采用概率积分法预计地表移动变形结果的精确与否 ,关键在于地表移动参数 .针对焦作矿区内巨厚松散层的地层条件 ,以条带开采地表移动实测资料为基础 ,用数学方法分析了巨厚松散层下条带开采地表移动规律及地表移动参数 。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.
