Abstract: In order to ensure the normal use of village buildings above 1501 working face of a coal mine, on the basis of the surface movement observation data, we study the laws of surface movement and deformation caused by 1501 working face mining by means of the probability integral method through the establishment of time-coordinate coordinate system. The results show that the expected function can accurately describe the global deformation of the surface at any point in the mining process, which meets the practical application of engineering.
