海石湾煤矿煤层伴生油页岩层自燃原因及对策

Causes and Countermeasures of Spontaneous Combustion in Oil Shale Seam of Haishiwan Mine

我国一些煤矿地质条件复杂,煤层伴生有油页岩层,其中局部含有密闭封存的油气,对矿井火灾防治及瓦斯防治造成危害。以窑街海石湾煤矿为例,采用试验的方法对油页岩样多元物性参数进行分析,获得了油页岩的孔隙分布特征、自燃倾向性以及氧化标志性气体,在此基础上,提出了综合的防灭火技术措施。

The geological conditions in some coal mines of China are very complex. Oil shale seam is even seen around coal seams. There a large amount of gas stored in this closed environment, which leads to a high risk of fire disaster. This article takes the Haishi- wan Mine in Yaojie as the research objective and gives a study on the physical parameters of oil shale. The pore distribution character, spontaneous combustion tendency and index gas of oxidation is obtained, which can be taken as the basement of fire prevention meas- urement.
