Abstract: Aiming at the condition that the national coal mine production safety situation remains serious, and serious accidents have not been effectively curbed, the article focused on the analysis of the current status of safety supervision informationization. By introducing the concept of the Internet of Things (IOT), the article put forward the view that IOT can be used to help the coal mine safety supervision authorities to strengthen monitoring on the implementation of safety main responsibility of coal mines, and analyzed specific applications of IOT in coal mine safety supervision deeply. It proposed networked remote inspection technology programs based on IOT, took networked timely supervision and treatment on human behavior, material status, environmental conditions, management status and other information, so as to enhance the effectiveness of coal mine supervision, to curb coal mine accidents continue to occur, and promoted the coal industry to develop safely and stably.
