摘要
针对高瓦斯大采高工作面开采过程中瓦斯与火共生致灾的难题,以斜沟煤矿18205工作面为研究对象来解决瓦斯抽采和自然发火综合治理之间的矛盾,利用数值模拟和现场实测相结合的研究方法,通过COMSOL模拟得到瓦斯抽采量及抽采口位置的变化对自燃三带的影响规律。
To solve the problem that in the process of large mining height mining, gas is in symbiosis with fire, resulting in disaster, in this paper the 18205 working face of Xiegou Coal Mine is taken as the research object in order to solve the contradiction between the gas drainage and spontaneous combustion comprehensive control, by using numerical simulation and feld measurement, the infuence law of gas drainage and extraction mouth position change on spontaneous combustion zones is obtained by COMSOL simulation.
