Abstract: In order to improve gas geological early warning ability under coal mine, the professional rating report is used to analyze the data collected by five major departments of coal mine in a standardized and systematic manner. Taking the gas geological early warning rating system as the center, through multi sectoral linkage, it achieves timely upload, report, data analysis. In the form of report, the rating and early warning is carried out for underground environment, and the multi transmission mode is adopted to achieve multi terminal real-time rating report check. The gas geology warning rating system can also be combined with a variety of system to form intelligent warning control system, it provides the important basis for coal mine safety.
