Gas explosion accidents, which are one of the main forms of industrial disasters, frequently occur in the process of production, usage, storage, and transportation of combustible gases. The explosions of combustible gases cause significant losses to the safety of people’s lives and property, severely hindering the development of the national economic and social progress. Effectively preventing, controlling and reducing the economic losses and casualties caused by gas explosions has become a key issue that needs to be solved. Due to the highly destructive and complex nature of gas explosion accidents, various countries have invested substantial financial resources into extensive research and have achieved considerable results.
