Abstract: Coal mine safety intelligence refers to the intelligent technology related to coal mine safety, which is a necessary technical means to realize the intelligent perception and accurate early warning of typical coal mine disasters, and is also an important support for coal mine safety production. The significance of coal mine safety intelligence to the development of coal industry is analyzed, and the research status and achievements of coal safety intelligence are summarized. In order to solve the problems of unclear technical system, less information fusion interaction and unbalanced technical development in the development of China's coal mine safety intelligence, the system architecture of coal mine safety intelligence is constructed, including the digitization of intelligent sensors, equipment IOT networking and safety fusion intelligence. This study clarifies the idea of relying on Coal Industry Internet to realize safety intelligence system construction and information fusion. Taking the key technologies of sensor digitization and reliability as the breakthrough point, this paper focuses on the analysis of the intelligent development of safety sensing technology. The digitization, networking, intelligence and other key technologies and their development ideas are proposed to promote the intelligent construction of coal mine safety and the high-quality development of coal industry.
