Abstract
A theoretical evaluation was made of the usefulness of fighting coal mine fire with inert gases. A review is made of existing applications that indicate that inert gas methods of fighting mine fires are routine in czechoslavakia and the U.S.S.R. Details are given of the calculation of inert gas requirements. If sudden ventilation changes can be avoided, the main inerting requirements are to prevent explosion hazards from methane, which is normally liberated in the mine. However, sudden ventilation changes during a fire complicate the inerting requirements owing to possible formation of flammable distillation products. Inert gas methods are considered for the prevention of explosion when fires are fought directly, during construction of seals, and for extinction of mine fires. In some instances it is believed that the use of inert gas could reduce sealing time requirements by an order of magnitude.
