Abstract: To implement the “double prevention and control” work and ensure safety production of coal mines, through the study of the problems existing in risk classification control and hidden danger investigation and control of coal mining enterprises, based on Internet +, cloud platform, intelligent mine, Internet of things, WebGIS and other technologies, a coal mine safety risk grading control and accident hidden danger investigation and control platform has been studied and designed, including double prevention responsibility system management, safety risk grading management, hidden danger investigation and management, coal mine “one map” intelligent analysis and mobile terminal dual control platform and other functions. Through the platform, it promotes the coal mine safety production standardization, informationization, intellectualized. It realizes the closed-loop management in the process of pre-risk classification control and in-progress hidden danger detection. It realizes the dynamic management and continuous improvement of safety production, and establishes a new mode of coal mine safety prevention management. safety culture, and promote the sustainable development of enterprises.
