| 摘 要： | 通过调研陈家山煤矿瓦斯抽放钻孔CO的出现情况，对矿井416回采工作面易燃煤层瓦斯抽放钻孔内CO产生来源进行了分析。经过实验研究，得出了煤炭低温氧化反应所产生的CO及其与温度之间的变化规律，发现反应初始阶段CO浓度降低。再根据现场瓦斯抽放钻孔布置状况，建立了钻内不同气体组分来源分析模型，经过分析知到钻孔CO主要来自钻孔煤壁以及相通的采空区，这一研究结果对指导煤矿现场预防自燃火灾起到一定的借鉴作用。 |

| Abstract： | Based on investigating the condition of CO occurred in the methane drainage boring at the 416 working face in Chenjiashan Mine, this paper analyzed the source of CO. By the experiment, it was found that CO can be produced during the coal oxygenation reaction at low temperature, and a special rule was discovered that the consistence of CO will become lower with the increase of temperature while the coal oxygenation reaction starting. Besides, an analyzing model about the source of mixed gases was set up based on real situation of methane drainage boring laying in the coal seam. It was found that different kinds come from different area, and the CO comes from boring wall and the goaf connected to the boring. The result plays a reference role for preventing the spontaneous combustion disaster in coal mines. |
