Abstract: China is the country with the most serious coal and gas outburst disaster in the world. Many in depth research and practice have been carried out in outburst prevention,and outburst prevention and control has achieved remarkable results. However,the outburst accidents still occur in recent years. In order to further improve the outburst prevention and control technology in deep mines and improve coal mine safety,intelligent level and coal safety guarantee ability,the research progress and current situation of outburst occurrence mechanism were analyzed,and the key technologies of coal and gas outburst prediction,monitoring and early warning means were expounded,and the measures and emerging technologies for preventing and controlling outburst were summarized systematically.China has made a series of innovative achievements in the theory and technology of coal and gas outburst mechanism,prediction,monitoring and prevention,and solved a large number of theoretical and technical problems. However,with the increase of coal mining depth,the risk of coal outburst is becoming more and more serious and complex. At the same time,the national requirements for coal mine safety production are becoming higher and higher.In view of the current situation and demand under the new situation,it is urgent to establish a more suitable theoretical and technical system for outburst prevention and control.Therefore,the future development trend and research prospect are proposed.In terms of outburst mechanism,the research on outburst coupling evolution mechanism and quantitative characterization should be strengthened under complex and changeable strata and different structural conditions. In terms of outburst risk identification,it is necessary to pay attention to the study of adaptive criteria for different outburst regions and categories risk under the background of low parameter outburst.In the aspect of gas parameter testing,the development of fine fixed point measurement and inversion while drilling should be focused.In terms of accurate detection/prediction/monitoring and early warning technology of prominent hazards in the working face,the research and application of internet of things,big data analysis and artificial intelligence identification technology in comprehensive monitoring and intelligent early warning of prominent hazards should be strengthened.In terms of prevention and control,the remote,regional and intelligent prevention and control technology of coal seam outburst risk should be further developed.In terms of risk management and control,it is necessary to study and promote the big data analysis and early warning platform of gas disaster risk,so as to comprehensively improve the ability of risk management and control of gas disasters and gas control level in China.
