In order to solve the mining problem caused by large coal seam inclination of +7 3 5 level in Xinj iang Dahuangshan mine,the mining features of large inclination in thick coal seam were analyzed,and the equipment selection and"threeGmachine"matching were researched according to the actual geological conditions.Besides,the safe measures for tilting prevention of supports were determined.Furthermore,strikeGlongwall miter slice fully mechanized caving was put forward.Field practice showed that the equipment selection satisfied geological and producG tion conditions of working face at +735 level,and the corresponding mining methods of strikeG longwall miter slice fully mechanized caving met mining requirements,achieving safe and high yield mining in Dahaugnshan Mine and providing a reference for fully mechanized caving in thick coal seam with large inclination.
