Abstract: Safety training work is the basis and guarantee of coal mine safety management, with the unceasing change of technology and the demand in recent years, the original training model and system have many shortcomings and indirectly cause frequent coal mine safety accidents. To solve above problems, from trajectory cross theory of accident causation theory, on the basis of analyzing the characteristics of coal mine training in China, using the theory of enterprise innovation, we analyze the problems of coal mine safety training in China, propose people-centered "trinity" safety training innovation model based on technology, jobs, study (including "631" training model, routing job descriptions by walking around, multi-channel multi-level safety training mode, and then propose suggestions and countermeasures of perfecting our country's coal mine safety training system.
