Methane and Coal Dust Problem in Underground Coal …
— Methane and coal dust explosions are among the most important risk factors that cause fatal occupationalaccidents in underground coal mining. One of the most important reasons for these explosions is inadequate orunfavourable ventilation conditions. In cases where the generally used classical ventilation systems are insufficient,attempts …
Coal Dust Explosion at Railroad Facility Damages Nearby Properties
Insufficient ventilation rates within the tunnel allowed the formation of a localized atmosphere, preventing adequate dissipation and removal of methane and coal dust. The initial combustion event produced a pressure wave that traveled in both the north and south directions along the North Reclaim Tunnel.
