This article is based on the “three times” coal mining surface movement prediction method of the research report abstracted. The main contents are as follows: 1. Using the probabilistic model and the theory of revolving surface, the method of determining the influence function with the measured subsidence curve is given. Secondly, the integral grid method (rectangular and circular grid Method), which is a simple method to solve the problem of surface deformation in mining area with arbitrary shape. Thirdly, the calculation program of the mobile deformation source in the fully submerged basin has basically solved the large-scale and complex problems that are difficult to be realized The problem of surface movement caused by horizontal and multi-seam mining; fourthly, using the superposition principle and the asymmetric negative exponential impact function, the problem of surface movement and deformation in steep coal seam is discussed, and the simplified method .
