摘　　要：煤岩瓦斯复合动力灾害是深部煤炭开采的重大安全隐患,探明其致灾机理、发展监测预警及防控技术是防治关键。提出了煤岩瓦斯复合动力灾害防治“四面体”理论,即分别从灾害分类、灾害机理、灾害预警、灾害防控4个层面概述煤岩瓦斯复合动力灾害研究进展。总结了以能量释放主体、初始瓦斯压力、载荷条件为主的复合动力灾害类型划分依据;梳理了理论分析尺度和实验室尺度下的复合动力灾害机理研究进展,发现应力路径、微裂纹动态演化和煤岩赋存地质因素临界指标是致灾机理研究的关键;概述了以前期灾害前兆信息判识、中期灾害前兆信息采集、后期灾害一体化监测预警为主线的复合动力灾害监测预警技术研究进展;揭示了复合动力灾害消能减灾一体化防控技术和多尺度分源防控关键技术科学内涵。在此基础上针对两淮矿区灾害特点,提出了深部强动载条件下复合动力灾害智能判识与预警方法和分区协同防控方法。基于当前研究进展,提出了煤岩瓦斯复合动力灾害研究亟待解决的问题,助力实现深部煤炭安全、精准、高效开采。Coal-rock-gas composite dynamic disaster is a major safety hazard in deep coal mining.Exploring its disaster mechanism and developing monitoring,early warning,prevention and control technologies are key to prevention and control.Therefore,the'tetrahedral'theory for the prevention and control of coal-rock-gas composite dynamic disasters is proposed.The theory summarizes the research progress of coal-rock-gas composite dynamic disasters from four levels:disaster classification,disaster mechanism,disaster warning,and disaster prevention and control.The study summarizes the basis for classifying the type of composite dynamic hazard based on the main body of energy release,initial gas pressure,and loading conditions.The study reviews the research progress on composite dynamic disaster mechanisms at both theoretical and laboratory scales.It is found that stress paths,dynamic evolution of microcracks,and critical indicators of geological factors associated with coal and rock occurrence are key to the study of disaster mechanisms.The paper summarizes the research progress of composite dynamic disaster monitoring and early warning technology, with the main focus on earlydisaster precursor information identification, mid-term disaster precursor information collection, and integratedmonitoring and early warning of later disasters. The study reveals the scientific connotation of integratedprevention and control technology for energy dissipation and disaster reduction in composite power disasters, aswell as key technologies for multi-scale and multi-source prevention and control. On this basis, based on thefeatures of disasters in the Lianghuai Mining Areas, intelligent identification and warning methods for compositedynamic disasters under deep strong dynamic load conditions and zoning collaborative prevention and controlmethods are proposed. Finally, based on current research progress, urgent issues in the study of coal-rock-gascomposite dynamic disasters are proposed to help achieve safe, precise, and efficient mining of d
