Abstract: Aiming at the occurrence of coal mine safety accidents caused by risk and hidden danger factors,this paper combines Internet technology with relevant laws and regulations of national coal mine safety, based on B/S mode, adopts layui design framework, JavaScript and Java language technology, puts forward the design and research of double prevention information management system for coal mine safety. By defining the target of system research and development, designed the overall architecture of the system, elaborated the system management mechanism and the function, used the FP-Growth algorithm to discover the relevance of hidden data in multi-dimensions. The system realizes the real-time support for the work of post personnel by the multi-terminal intelligent linkage mode; improves the level of coal mine information management through the visualization of risk information; carries out real-time statistical analysis of risk and hidden danger information, and provides technical support for the double prevention decision-making of coal mine safety.
