In a typical mine on fire, the mine atmosphere may contain methane, hydrogen, and carbon monoxide as combustible gases and nitrogen and carbon dioxide as inert gases. Zabetakis [4] developed a flammability diagram for such gas mixtures. All combustible gases were combined and called (23.1) Flammability diagrams show the control of flammability in mixtures of fuel, oxygen and an inert gas, typically nitrogen.

Webthe vapor pressure curve L4U3' U2 are flammable. The flammable range is the same as that de-picted in figure 2. At constant temperature (for example, T1), the flammable … Lower flammability limit (LFL): The lowest concentration (percentage) of a gas or a vapor in air capable of producing a flash of fire in the presence of an ignition source (arc, flame, heat). The term is considered by many safety professionals to be the same as the lower explosive level (LEL). At a concentration in air lower than the LFL, gas mixtures are "too lean" to burn. Methane gas has an LFL of 4.4%. If the atmosphere has less than 4.4% methane, an explosion cannot o…
