The dual prevention mechanism serves as the core framework for safety management in underground coal mines, yet the risk coupling effect often causes single risks to evolve into major accidents. Integrating the Human Factors Analysis and Classification System (HFACS) with the Improved Analytic Hierarchy Process (IAHP) to construct a risk coupling model can effectively address this issue. The model decomposes risk factors in dimensions such as human, machine, environment, and management through HFACS, and quantifies the coupling intensity between factors with the help of IAHP to identify key coupling paths and risk areas. This model not only realizes the systematic sorting of risk factors but also improves the accuracy of coupled risk assessment, providing a scientific tool for risk classification management and hidden danger investigation and governance in underground coal mines, and helping the dual prevention mechanism to take effect.
