摘要
通过对北皂煤矿采空区煤炭氧化自燃模拟实验,以及对采空区温度、气体成分进行测定分析,得出北皂煤矿4402综采放顶煤工作面采空区的煤炭自然发火特性,从而为合理选择预防采空区煤炭自然的措施提供了科学依据。
By the imitate experiment of coal oxidized and spontaneous combustion, and measurement analysis of the temperature and the component of gas in Gob of Beizao coal mine, we can gain the spontaneous combustion firing characteristics in Gob of the 4402 full - mechanized sublevel caving faces in Belzao coal mine. Consequently, it offers the scientific gist to choose the precautions of spontaneous combustion of the coal in Gob.
