Experiment study on the propagation laws of gas and coal dust explosion in coal mine

Science in China Series A: Mathematics, 2009
The experiment of gas and coal dust explosion propagation in a single laneway was carried out in a large experimental roadway that is nearly the same with actual environment and geometry conditions. In the experiment, the time when the gas and coal dust explosion flame reaches test points has a logarithmic function relation with the test point ...

Coal Dust and Gas Explosion Suppression by Barriers

1987
Explosion suppression barriers are devices that contain fire extinguishants that are activated to disperse at some critical point during the propagation of an explosion to suppress it. Suppression of coal dust explosions using barriers (both triggered and passive) has been investigated by the U.S. Bureau of Mines. The work reported in the present study

Influences of a Pipeline’s Bending Angle on the Propagation Law of Coal Dust Explosion Induced by Gas Explosion

Combustion Science and Technology, 2019
A pipeline explosion system with different bending angles (45°, 60°, 90°, 120°, and 135°) was constructed to investigate the influences of the pipeline’s bending angles on the propagation law of co...
