Abstract: With the continuous development of coal mine automation and information construction, a large number of production technologies, business management, monitoring and controlling, integrated automation and other types of data have been produced during the mining process. Most of the utilization of these massive data is still in the basic statistical summary and presentation stage. This paper introduces how to use big data technology to establish the auxiliary management model of coal mine safety production, to carry on the unified integrated management and depth mining of the mass data accumulated in the mine. Taking the big data application practice in the construction of “Yangquan Coal Mine Safe Production and Operation Management Platform” as an example, and the significance for improving the management level of coal mine safety production is illustrated.
