Abstract: For problems that existing coal mine safety management systems focused on data monitoring and analysis based on a single object without comprehensive analysis, and there was no effective integration among the systems, a new coal mine safety management platform was proposed which was based on Internet of things technology, and design schemes of the whole structure and each layer of the platform were introduced. The platform can realize functions of illegal behavior monitoring, disaster warning and risk analysis through integrating related safety management systems and comprehensive analysis of all kinds of coal mine data.
