Based on a comprehensive analysis of the current situation of resource occurrence and system status in the Shajihai coal mine integration area, it is proposed to use the existing industrial site and ground facilities. Through technical and economic comparison, the advantages and disadvantages of two development plans are compared from multiple perspectives. The development plan of building a new gentle slope auxiliary inclined shaft, using the original main inclined shaft, pedestrian inclined shaft, and return air vertical shaft, and transforming the original auxiliary inclined shaft into a concealed return air inclined shaft is determined. This plan can achieve the rationalization and maximization of resource development in the integration area, promote the scientific and balanced development of the mine, and comprehensively consider the production needs of the mine in the middle and later stages, laying the foundation for safe and efficient production of the coal mine.
