Abstract: In order to study the influence of wide strip mining on the village surface movement deformation, and establish suitable mining parameters, the paper analyze the data of surface movement deformation of the first panel strip working face based on the actual conditions of Tingnan Coal Mine. And the paper gets the law of surface movement and deformation of wide strip mining under the geological mining conditions. Combination of theoretical calculations and numerical simulation methods, Optimized strip mining options. The results show, it can be used to effectively control the thick coal seam wide strip fully mechanized caving mining surface movement deformation when the mining width is 100-116m and the leave width is 80-100m,which can realize safe mining under the first panel surface village buildings. The research results can provide basis for wide strip mining under the village buildings in Tingnan Coal Mine and Binchang Mining Area.
