Based on Numerical Simulation to Investigate the Process of Gas Explosion Accident in Coal Mine

摘要：

　　The gas is one of the most important factors which endanger the security of the mining production.Most of serious accidents are the gas explosion accidents in coal mine.By investigating the damage situations of the gas explosion accidents and the related material,finding out why these incidents happen is an important way to prevent or reduce the gas explosion accidents.Based on the occurred gas explosion accidents,the author use the FLUENT software to simulate the process of gas explosion and get the variation law of various air current parameters is obtained in gas explosion.The explosion causes and development course are discussed.Compared with the explosion parameters collected on scene of accident,it provides comprehensive scientific basis for the accident investigation.The conclusion is helpful to adopt suitable measures to prevent the gas explosion.
