Abstract: Using coal mine safety technology theory, mining engineering technology, computer technology, GIS technology and scientific calculation method and so on, the research of advanced early-warning theory and technology system of gas disasters can realize the anticipation of gas disasters. According to the characteristics and laws of gas disasters in Chengzhuang Coal Mine, we make early warning indicators and rules for gas overrun and outburst, and develop early warning system, which realizes the gas early warning and management of intelligent.
