Richard C. Gilmore Publications

ABSTRACT Underground longwall coal mining sections may develop explosive mixtures of methane-air in the mined-out gobs. If the panels are operated as bleederless or sealed gobs, progressive sealing along the gateroads as the longwall face retreats limits the flow of fresh air into the gob and thus deprives potentially explosive atmospheres of ...

Explosion Prevention In Mining

Mixtures of methane in the air can also become explosive at concentrations of 5 to 15, with 9.5 being its most dangerous concentration, as its ability to react with oxygen within the mine allows for the massive production of heat that will induce an explosion 2.
