Abstract: The four-color map is a standard and new method of security visualization management. In order to improve the accuracy of risk identification and assessment and the level of coal mine safety management, and keep up with the development trend of informatization and intelligence of coal mine safety management, a dynamic management and control system of coal mine safety risk four-color map based on cloud model is built to solve the problems of complex and changeable underground working environment, inadequate hidden danger investigation and weak accuracy and guidance of coal mine safety risk four-color map. The system is mainly composed of hardware and system support software. The cloud model risk assessment system embedded in the system is used to evaluate the risk level of each risk point in the coal mine, and the corresponding risk level color is displayed according to the results. It overcomes the disadvantages of low efficiency of traditional coal mine safety risk control, combines risk assessment level with prevention and control measures, and realizes real-time assessment and dynamic management of coal mine safety risk. The combination of cloud model and four-color map solves the fuzziness and uncertainty of the system in the classification process through the cloud model, and uses the four-color map to visually display the risk classification, which provides theoretical support for scientific coal mine risk management. The system has been successfully applied in Shanxi Lu’an Wuyang Mine, providing support for the informatization and intelligent development of safety management in more coal mines.
