Abstract: In order to understand the evolution of digital research on coal mine safety management technology, this paper, based on the “man-machine-environment-management” safety production theory, using literature research method, analyzed the factors affecting coal mine safety management and summarized the digital process of coal mine safety management technology as well as the current research status. It is believed that the future of digital mine safety management will use the “man-machine-environment-management” safety production theory as a research framework to achieve deep integration of coal mines with artificial intelligence, internet of things, big data and cloud computing.
