I don’t know what the author is talking about coal mining leaving scars. Coal mining is crucial to everyone and everything in the area. It leaves up with land that we can actually use to build houses, stores, etc. The economy is thrives from the coal miniers and when it goes the economy will drop and this will become a ghost town.
As coal mining moves to deeper and gassier mines, operators increasingly may remove the gas by pipe drainage prior to mining in order to decrease the amount of air needed for ventilation since achieving the air volumes required is becoming both costly (shafts, fans, stoppings, etc.) and technically difficult.
For underground coal mine explosions, coal dust and methane are typically the primary fuels involved. Methane may also be present in non-coal mines and is most commonly handled by dilution with ventilation air and exhaustion from the mine (Timmons, Vinson and Kissell 1979).
