Abstract: In view of the serious problem of information isolated island and the lag of hidden danger disposal in Xiahuo Coal Mine, based on the four-dimensional integration concept of "human machine environment management", a security intelligent management and control cloud platform was built, and the business system of "six tier technical architecture+nine functional subsystems" was proposed, integrating key technologies such as multi-source heterogeneous data processing, image recognition, knowledge map and data mining. The platform deployment covered more than 700 sets of sensing equipment, and collected more than 2 million pieces of data on a daily basis, which improved the accuracy of risk identification from 65% to more than 92%, shortened the time for potential hazard disposal from 48 hours to less than 2 hours, automatically identified more than 60 violations every month, improved the efficiency of rectification by 66%, and reduced the cost of control by 21%. The research results show that the platform significantly improves the intelligence level and operation efficiency of safety management in Xiahuo Coal Mine, and provides a feasible path for realizing intrinsic safety.
