The distribution of O2 concentration in the goaf under different inert gas injection sites. (a) Distribution of O2 concentration in the goaf at X = 30 (m). (b) Distribution of O2 concentration in the goaf at X = 40 (m). (c) Distribution of O2 concentration in the goaf when X = 50 (m). (d) Distribution of O2 concentration in the goaf when X = 60 m.
