Abstract: In recent years, the domestic coal mine safety situation has improved, but accidents still occur frequently. The importance of comprehensive construction of safety management and control systems is becoming increasingly prominent. The gradual improvement of the informatization and automation level of coal mine enterprises provides a diversified mass data base for the realization of coal mine safety management and control systems. The article proposes a big data platform construction plan for smart mine safety management and control, which is based on big data technology, the current coal mine industry security situation and information systems status. The platform can solve comprehensive data and information collection issues, adapt to industry characteristics, and build the risk warning and research function modules by using big data fusion and deep mining. The platform forms five key technologies. With the improvement of coal mine informatization and the deep application of data mining technology, the big data platform will certainly provide wider and more effective decision support for production managers.
