Research on the propagation of pressure and CO gas of methane and coal dust coupled explosion
Thermal Science, 2022 A methane and coal dust explosion system was constructed to investigate the propagation of pressure and CO gas after methane and coal dust coupling explosion. The influence of coal dust concentration on the propagation of pressure and CO gas were analyzed by coupling explosion experiments of 5% methane with coal dust (0, 100 g/m3, 200 g/m3, 300 g/m3 ...
