Explosion behavior,hazards,and protection research progress on coal seam gas
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 pro-gress 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,ex-plosion 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.
