Occurrence of spontaneous heating in coal pillars is one of the most feared hazards in underground coal mines. It may turn into serious conflagration and pollute the entire atmosphere in the mine in a very short time. To prevent/control such fire, knowledge of air permeability of particular pillar will be useful. After realizing the need the authors have developed a methodology for measurement of air permeability of coal pillars. In this paper definition of air permeability, its unit and methodology for its measurement have been briefly discussed.
