【 摘 要 】

With the increase of mining depth, many coal mines have the co-occurrence of natural fire and gas disasters. According to the actual situation of alkali ditch coal mine, this paper established a mathematical model and geometric model of mined-out area by using COMSOL software to carry on the numerical simulation. Study of nitrogen injection and gas extraction of goaf flow field and the influence of oxidation temperature zone, provided the basis for mine fire and gas disaster prevention and control.
