对于煤自燃倾向性的测定,目前常用的两种方法是:(1)测定煤的着火温度;(2)测定煤吸氧量的方法.以往的成果得出煤的自燃倾向性除了采矿因素外,还与煤的其它物化性质以及它的变质程度有关.然而对后者的研究甚少.用煤岩学的方法对氧化煤的研究起因于对矿井失火和煤的自燃倾向性的研究.费拉1938年在西德鲁尔煤田海因里希罗伯特矿调查矿井着火时就指出“镜煤在煤着火上起
For the determination of coal spontaneous combustion tendencies, the two commonly used methods are: (1) Determination of the ignition temperature of coal; (2) Determination of oxygen absorption method of coal. Past results come out that the propensity to spontaneous combustion of coal in addition to mining factors , But also with other physical and chemical properties of coal and its degree of metamorphism.However, little research has been done on the latter.Studies on the oxidized coal by the method of coal petrology result from the research on the misfire of mine and the spontaneous combustion tendency of coal. In 1938, when investigating a mine fire at the Heinrich Robert Mine in West Druid coalfield, he pointed out that "the mirror coal landed on a coal fire
