In order to make the coal mine environment safer, ventilation air systems are now installed in mines, which add air and ventilate the mines at high flow rates, resulting in a Ventilated Air Methane stream (referred to as VAM), with CH 4 in concentrations between 0.2-1.2% by volume. This air is then typically vented to the atmosphere.
