Abstract: As one of the "three under" coal pressure problems, village coal pressure has long puzzled the sustainable development of the mine. How to extract the pressure coal resources by reasonable mining method is an important subject of "three under" mining work in our country at present. In this paper, by comparing and analyzing the economic benefits of various mining schemes to solve the problem of village coal pressure, the short-wall interval filling mining method is adopted to extract the village coal pressure mining area of Liudong Coal Mine. Combined with theoretical analysis, physical simulation and FLAC3D numerical simulation calculation method, the strip filling mining technology parameters and mining technology are determined. Finally, the short-wall interval filling mining technology has been successfully applied to the mining area of village coal pressure, which has a reference significance for the mining scheme of village coal pressure and the way of village relocation under similar conditions
