Depending on the area and layout of the individual mine fire; one or more delivery tubes are drilled down to be close the burning coal veins. Temporary bulkheads may be necessary to force the Liquid Nitrogen into the coal vein. Once introduced, the extremely cold and incombustible gas will knock out two of the three legs of a fire triangle.

1) Reducing temperature and
