In order to evaluate the impact ground pressure hazard more reasonably and avoid the uncertainty of impact ground pressure evaluation results, the possibility of impact ground pressure was analyzed by combining the physical and mechanical properties of coal rocks in a mining area with a comprehensive mining face of 16-4 coal seam as the research object. The risk assessment of the compre-hensive mining working face was carried out by the comprehensive index method, and it was determined that the impact ground pressure risk index of the working face is 0. 23, which is no impact risk. It provides a reliable basis for the prevention and control of impact pressure in this mine.
