Abstract Through the comprehensive analysis and research on the geological characteristics, coal seam and coal accumulation law of Jijihu West Minefield, it was concluded that Xishanyao Formation experienced many times of lake into and retreat during the coal-forming period, and it was in the alternating environment of shallow lake and swamp for a long time, forming the characteristics of many coal layers, uneven thickness and bifurcation merger. Combined with the hydrogeological conditions, engineering geological conditions, environmental geological conditions and other mining technical conditions of Xishanyao Formation, it was showed that the hydrogeological conditions were simple ; the engineering geological conditions were poor in the study area, with the characteristics of medium integrity-poor integrity-broken rock mass and poor stability of coal seam roof and floor rock. Environmental geological conditions were medium, coal seam gas content was low, explosive, flammable and so on. The study provided reference for the further development and construction in the study area.
