The quantity of air required by law or practical considerations to maintain adequate ventilation of a mine. This quantity will depend on (1) the length of face room in production, (2) the average distance from the shafts to the faces, (3) the gas emission rate, (4) the depth of the workings, and (5) the volumetric efficiency of the mine ventilation. See also: air volume; ventilation planning.
