Experiment and Study on Gas Explosion Features in Simulated Mine Roadway

According to the conditions of the mine gas explosion accidents frequently occurred in the recent years,the horizontal pipelines with different lengths were applied to simulate the gas explosion in the mine roadway to study the explosion limits of the gas explosion,the max explosion pressure and density,the max explosion pressure rising velocity and explosion features.The paper also analyzed the variation conditions of the gas explosion pressure in the pipeline in order to provide the theoretical references to prevent the gas explosion in the mine roadway.
