Safety production is a crucial guarantee for the country's economic development, and the safety double prevention mechanism is an effective way to realize safety production. In order to improve the operating effectiveness of the safety double prevention mechanism of coal mine enterprises, this paper preliminarily constructs the evaluation indicator system for the operating effectiveness of the safety double prevention mechanism of coal mine enterprises based on the accident cases and literature analysis. A questionnaire was designed, and the collected data was analyzed for reliability and validity to examine the indicator system. This resulted in constructing an indicator system that evaluates the operating effectiveness of coal mine enterprises' safety double prevention mechanism. This system comprises five first-level and 30 second-level indicators for risk hierarchical control, hidden danger investigation and treatment, inspection review and update, employee safety management, and safety guarantee management. Subsequently, this paper utilized the analytic hierarchy process-entropy weight method to empower the evaluation indicators and then constructed the matter-element extension model to evaluate the operating effectiveness of coal mine enterprises' safety double preventive mechanism. Finally, the Y coal mine enterprise is taken as an example for empirical analysis. The results show that the operating effectiveness of Y coal mine enterprise's safety double prevention mechanism has reached a good level in general. However, some evaluation indicators still have a low evaluation level, which is consistent with the actual safety situation of Y coal mine enterprises. This verifies that the evaluation indicators and model established in this paper have strong applicability and scientificity.
