Abstract：Under high-intensity mining conditions,the safety status of working face is affected by the coupling effect of single or multi-ple factors,and there is a certain degree of uncertainty in evaluating the overall safety status of working face and obtaining its main con-trol factors causing disasters.The study extracted the constituent elements of coal mine safety risks and conducted a coupled multi factor analysis of potential coal mine risks using information entropy theory,effectively identifying their main controlling factors.By using at-tribute recognition method,the scientific division of neighborhood values of various safety indicators under coal seam geological condi-tions and disturbance effects has been achieved.A multi factor coupled working face risk assessment model based on entropy weight was constructed,which achieved a horizontal comparison of disaster prone environments and safety conditions under strong coal mining with different coal seam occurrence conditions.This provides a more scientific method for identifying and preventing the main controlling fac-tors of working face disasters under multi factor coupling.
