The use of inert gas systems to extinguish mine fires has been the subject of research for some time in the United States. In some European countries it is an established practice. Tests were conducted with the Central Mining Institute (CMI) inert gas system, which is being used by the Polish mining industry. This system utilizes a modified jet aircraft engine and afterburner as a compact source of combustion products with a very low oxygen content. Water injected into the combustion products stream provides evaporative cooling and forms a mist with a high cooling capacity. The CMI system was used under controlled conditions to extinguish coal pile fires at the Bureau of Mines experimental mine in Bruceton, Pennsylvania. The tests results show that the cmi system can be used conveniently to extinguish fires quickly and to maintain an inert atmosphere in the fire zone to prevent reignition.
