Abstract: In response to a series of problems caused by the complexity of auxiliary lifting and transportation systems in the development process of gently inclined coal seam groups, it is proposed to transform the Shajihai No.1 mine into an auxiliary lifting and transportation system with the goal of trackless auxiliary transportation system and the construction of a new gentle slope inclined shaft as the transformation method. Combined with the layout of the shaft, the mine is optimized and designed for development. The coal seam group is developed by using gentle slope inclined shafts as auxiliary transportation for mining areas to reduce the number of mining areas and extend the service life of each mining area, which is conducive to alleviating the tense situation of mining and excavation continuity. The optimization ideas for the development of Shajihai No.1 mine have certain reference significance for the development of coal seams in Xinjiang.
