Abstract: Abstract: In order to reasonably determine the mining method and process parameters of the working face in Binchang mining area, this paper studies the types and characteristics of typical disasters in the mining area on the basis of summarizing the resource conditions of Binchang mining area and field research on the production of many mines in the mining area. The interaction relationship of each disaster itself and the constraints and influences of disasters on mining activities are analyzed. The principles and methods for determining coal mining methods and face parameters under multiple disasters are proposed. The results show that the coal mining method in Binchang mining area should adopt top coal caving, and the coal caving height is restricted by the height of the overlying water blocking layer; the safety critical value of the fully mechanized caving face length is generally within 180m; the working surface propulsion speed should be 3.2~4.8m/d; the face advancement length is generally within 2.3km.
