3) coal spontaneous combustion
煤层自燃
1.
To effectively control coal spontaneous combustion in coal mines,a key component is to accurately locate the zone of the spontaneous combustion with a radon-based technique,and the equally important component is the detection and measurement of the temperature information related to the zone(s) which can be used to develop the optimum design of controlling the spontaneous combustion.
在煤矿自燃火区的治理过程中,同位素测氡法探测煤层自燃火源精确位置是火区治理的关键技术,而火区信息的采集为灭火方案及灭火参数提供可靠依据。

内蒙古西部乌达矿区煤层自燃的控制因素
2.
The mechanism and area size of spontaneous combustion of coal seams is mainly influenced by the factors of palaeogeomorphology,palaeoclimate, lower metamorphic degree of coal and higher amount of fusinized matter.
根据对神府煤田休罗纪煤层自燃区的详细观察和分析,论述了煤层自燃的特征,确定了煤层自燃的时代,进一步讨论了煤层的自燃机理和最终自燃范围,认为本区煤层自燃主要受古地貌、古气候和低的煤变质程度以及惰质组的高含量等因素的影响,且惰质组是煤层自燃的关键和导火物质。

井下煤层自燃严重危害着安全生产。
2.
The spontaneous combustion of coal seam,environment control and some other problems in Luotuoshan coalmine and Wuda coalmine of Wuhai city are investigated and analyzed profoundly in this paper,and some opinions and suggestions are put forward as well.
本文对乌海市骆驼山煤田和乌达煤田煤层自燃情况、治理情况、存在问题等进行了深入调研和分析,并提出了具体意见和建议。
补充资料：自燃
分子式：
CAS号：
性质：一种非人为点燃或加温而自然燃烧的现象。通常是在常温下，由于可燃物和空气中氧进行缓慢氧化积聚热量致使温度达到该物燃点所引起的。例如，白磷在空气中缓慢氧化，在白磷表面积聚的热量使温度达到40℃以上时，白磷即自发燃烧。稻草、煤炭、棉纱等易燃物，若储藏或堆放不合理，也会发生自燃。
