Based on the study of the geological data of the southern six regions of the Fangezhuang Mine, by the analysis and research of the geological data of the ground drilling and geophysical data in Bigezhuang syncline area and the 3621S wind transportation roadway and adjacent projects in the Fangezhuang Mine, the geological factors affecting the mining of the 3621S working face of the mine were analyzed and predicted. A solution for the F4 and F9 faults in the working face was given, which provided important geological guarantee for production.
