摘　　要：为研究某矿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,设计试验室自燃基础参数测试和现场的温度、气体监测试验,得到60、61煤层自燃特性和采空区内温度、气体情况。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。In order to study the original ignition source of gas burning at 6135 working face to guide the prevention and treatment of gas burning incidents,laboratory basic parameters of spontaneous combustion and field temperature,gas monitoring experiment were designed,and spontaneous combustion characteristics of 60 and 61 coal seams and the temperature,the gases situations in gob were obtained. The result showed that the probability of polyurethane self- heating 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.
