Abstract: Close distance coal seams were mined mainly in the south of Sichuan Mining Area, due to the limitation of the geological occurrence condition and the mining method, some coal bodies can not be produced and form high coal during the lower coal seam mining period. The high level residual coal is affected by mining after entering goaf, the serious spontaneous combustion accidents often occur in the mining area, which brings serious threat to the safe production of the mine. Based on this, this paper takes 118-12 working face in Chuanjing Coal Mine as an example, and carries out the research on the control technology of spontaneous combustion of high residual coal in the course of close distance coal seams mining. On the basis of analyzing the influence factors of spontaneous combustion of the working face, a high-level intubation grouting between the working faces is proposed. On the basis of ensuring the safety mining of working face, the secondary influence of resudual coal on overlying coal seam mining is eliminated.
