Abstract：The amount of overlying coal resources under buildings and villages in Xingyu Coal Industry of Huayang Group accounts for about 50 %. The amount of relocation work is large and difficult, which seriously restricts the resource mining and sustainable development of the mine. Aiming at the problem of mining coal resources under buildings and villages, taking 15107 working face of the first mining area of Xingyu Coal Industry as a pilot, the research on grouting technology of key strata of overburden separation is carried out, and the filling mining of protective coal pillars is carried out, which effectively solves the problem of safe mining of coal under buildings and villages, improves the recovery rate of coal resources, protects the underground and surface environment, and provides technical reference for green mining of mines with the same geological conditions.
