| 摘 要： | 为研究祁东煤矿6135工作面瓦斯燃烧发火原因,以指导瓦斯燃烧事故的治理和预防工作,设计实验室自燃基础参数测试和现场的温度、气体监测实验,得到60、61煤层自燃特性和采空区内温度、气体情况。经分析结果表明:聚氨酯自热及高强度抽采漏风引起60煤体自燃为瓦斯燃烧引火源的可能性较小,6135机巷断层附近保留煤柱氧化自燃为工作面瓦斯燃烧事故的引火源。

| Abstract: | In order to study the original ignition source of gas combustion at 6135 working face, which can help to guide the prevention and treatment of such incidents, the basic spontaneous combustion parameters of 60 and 61coal was tested in laboratory, and a field experiment to obtain and monitor gas concentration and temperature of gob was designed and carried out. The result showed that the probability of polyurethane selfheating and 60 coal mine spontaneous combustion with gas extracting was very small, and coal pillar spontaneous of the geological formation at 6135 belt conveyor lane was the original ignition source. |
