煤层自燃是由于多种外在因素加速煤内在的氧化所引起的。煤的氧化倾向性主要与煤的内在特性有关,各种煤的氧化倾向性均不相同。本文叙述一种利用绝热氧化技术来直接确定煤氧化倾向性的实用方法。 长期以来,煤自燃威胁着煤炭的开采和储存管理,为了解决这个问题,已进行了大量的研究,对自燃作出了许多解释,但没有提出具体的解决方法。回顾过去所作的研究工作,可得出结论。在开采期间,不可能完全排除煤层中所有的自然灾害。 Coal seam spontaneous combustion is due to a variety of external factors to accelerate the internal oxidation of coal caused. The oxidation tendency of coal is mainly related to the inherent characteristics of coal, and the oxidation tendency of various coal is different. This article describes a practical method of using adiabatic oxidation techniques to directly determine the propensity for coal oxidation. For a long time, spontaneous combustion of coal threatened coal mining and storage management. To solve this problem, a great deal of research has been done and many explanations have been made on spontaneous combustion. However, no specific solution has been proposed. Review the research done in the past and draw conclusions. During the mining, it is impossible to completely rule out all the natural disasters in the coal seam.
