Abstract：Foamed gel was studied as a new type of material for mitigating coal mine fires and gas accidents.The Ross-Miles method was used to identify a surfactant capable of creating at least 22 cm high foam at a relatively low dose.The parameters of the foam were studied.The foamed gel has perfect stability and holds water for ten days at normal temperatures and pressures.The gel is able to hold back coal gas and form a plug.Inhibition experiments showed that the rise in coal temperature was controlled by the foam.The inhibition rate was 62.23%,which effectively reduces coal oxidation rate and controls the release of CO.
