Effect Of Coal Mine Organic Aerosol On The Methane Air

Effect Of Coal Mine Organic Aerosol On The Methane Air

Mar 28 2020 Organic aerosol is formed in coal mines due to heat release and evaporation of organics from coal during the longwall operation This frictional heating occurs when a metallic cutting bit strikes a rock Thus formed organic aerosol can contribute significantly to the explosivity of methane air atmosphere in coal mines In this paper the flammable limits for the methane–air mixtures with
