Abstract: In order to explore new technologies for the prevention and control of abnormal gas emission disasters in coal mines, develop intelligent early warning and prevention and control equipment for gas disasters, and ensure the safe and efficient mining of high gas mines, based on the complex characteristics of abnormal gas emission disasters in coal mines. The research results and practical experience are obtained from the four aspects of gas geological anomaly area detection technology, ventilation dilution abnormal gas technology, drainage technology in abnormal gas area and emergency treatment of abnormal gas emission, and from the aspects of dynamic transparent gas geology, multi-source information intelligent detection technology, big data mining technology of abnormal gas emission, intelligent prevention and control technology of abnormal gas emission, robot emergency rescue technology for abnormal gas emission accident, five aspects are prospected, which points out the direction for improving the disaster prevention and control ability of abnormal gas emission in coal mine and reducing the occurrence of mine safety accidents.
