Suppression effect of solid inertants on coal dust explosion

Journal of Measurement Science and Instrumentation, 2018
The effect of solid inertants like rock dust on explosion suppression was experimentally tested.By adding solid inertants with different concentrations into three kinds of coal dust,the maximum explosion pressure Pmaxand the rate of explosion pressure ...

Explosion severity of methane-coal dust hybrid mixtures in a ducted spherical vessel

, 2018
This article reports an investigation on the explosion characteristics of methane-coal dust hybrid mixtures in a ducted spherical vessel. Methane-coal dust hybrid mixture explosion can occur in coal mines and spread into mine tunnels. While investigating
