Propagation laws of discontinuous gas supply in the excavation roadway.
PLoS ONE, 2022 An explosion with a discontinuous gas supply (DGS-explosion) is more complicated than a common secondary explosion. We present the results of a study on the propagation laws of the DGS-explosion induced by a gas explosion in excavation roadways.
