Most of previous works look at the fuel content of the mixture, or the explosibility. Here we are proposing a progress variable to check both fuel and oxygen for diagnosing what is the status of fire after sealing, and when the sealed atmosphere is explosive if a leaking is allowed. In essence, the flammability problem of mine gases is a mixture problem of multiple fuels, with carbon dioxide as the diluent, in an oxygen-modified air [ 1]. In order to determine the status of a sealed fire, a progress variable, heating/quenching ratio, is proposed as the completion between heating and quenching, whereas heating can be oxygen-based or fuel-based.
