摘　　要：煤层气逐渐成为当下能源的组成部分之一,其本身危险性仍伴随着事故的发生,造成的事故也逐渐增多,即敲响了我国安全发展的警钟,也表明了面对瓦斯爆炸事故的认识不足和经验不够。从瓦斯气体应用、发展以及爆炸的理论、爆炸特征、危害和气体爆炸防护研究方面介绍了目前的研究进展,介绍了目前气体爆炸理论、最小点火能、爆炸极限、传播规律和数值模拟研究,总结了目前瓦斯气体爆炸危害的研究进展,重点分析了针对性的瓦斯爆炸防范的有效措施,指出了研究的不足和今后的发展方向。对比了国内外可燃气体方面在风险识别、危险防控、安全管理等方面的优势与不足,促进了可燃气体的安全使用并减少了爆炸伤害,有力地保障了国家的发展和稳定。In recent years,coalbed methane has gradually become one of the current energy components,its own risk is still accompanied by the occurrence of accidents,resulting in an increasing number of accidents,which sounded the alarm of China′s safety development,but also shows the lack of understanding and experience of the measures in the face of gas explosion accidents.The current research progress was introduced in the application and development of gas,as well as the explosion theory,explosion characteristics,hazards,and protection research against gas explosions.It also introduced the current research on gas explosion theory,minimum ignition energy,explosion limit,propagation law,and numerical simulation.It summarized the current research progress on the hazards of gas explosions,analyzed effective measures for targeted gas explosion prevention,and pointed out the shortcomings of research and future development directions.Compared with the advantages and disadvantages of risk identification,danger prevention and control,and safety management of combustible gas at home and abroad,it promotes the safe use of combustible gas and reduces the explosion damage,and effectively guarantees the development and stability of the country.
