我国煤与瓦斯突出防治理论技术研究进展与展望

我国是世界上煤与瓦斯突出灾害最为严重的国家，在突出预防方面进行了大量深入的研究和实践，突出防治取得了较为显著的效果，但近年来突出灾害事故仍时有发生。为了进一步提高深部矿井煤与瓦斯突出防控技术，提升煤矿安全、智能化水平和煤炭安全保障能力，分析了突出发生机理研究进展及现状，阐述了我国煤与瓦斯突出预测及监测预警手段的关键技术，系统总结了防治煤与瓦斯突出的措施及新兴技术。我国在煤与瓦斯突出机理、预测、监测和防治等理论与技术方面取得了系列创新性成果，解决了大量理论和技术难题。但是，随着我国煤矿开采深度的增加，煤矿突出危险性日趋严重复杂。与此同时，国家对煤矿安全生产的要求也越来越高。针对新形势下煤与瓦斯突出防治现状和需求，亟需建立更为适应完善的煤与瓦斯突出防治理论及技术体系。基于此，提出了未来发展趋势及研究展望：在突出机理方面，应加强复杂多变地层及不同构造条件下突出耦合演化机理和定量化表征研究；在突出危险性鉴定方面，需关注低参数突出多发背景下不同区域及类别突出危险性的适应性判定标准研究；在瓦斯参数测试方面，应聚焦精细化定点测量及随钻反演技术的发展；在工作面突出危险性精准探测/预测/监测预警技术方面...

Research progress and prospect on theory and technology for coal andgas outburst control and protection in China

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.
