| 摘 要： | 福建省煤系石墨赋存层位为中二叠统童子岩组含煤岩系地层,该地层中的煤炭,由于受岩浆侵入及构造运动作用,已变质成无烟煤,如受温度与压力的作用更强烈,进一步变质成隐晶质石墨;无烟煤与煤系石墨在宏观上难以区别,相关规范仅以固定碳和挥发分作为确定石墨的工业指标,是无法对两者进行区分的。鉴于此,综合国内对煤系石墨工业指标划分,结合《福建省煤系石墨赋存规律与资源评价》课题的最新研究成果,尝试采用以固定碳、挥发分作为划分无烟煤与煤系(隐晶质)石墨的基础指标,以石墨碳层间距d 002和拉曼光谱参数R 2作为精确指标,建立煤系石墨鉴定方法体系,以便科学评价和利用煤系石墨资源。

| Abstract: | Graphite is hosted in the middle Permian Tongziyan Formation coal measures strata.Because of magmatic intrusion and tectonic movement,coal has been metamorphosed into anthracite.If it is impacted by thermal and pressure actions stronger will further metamorphosed into cryptocrystalline graphite.Macroscopically,anthracite and coal measures graphite is difficult to differentiate.Relevant specifications only take fixed carbon and volatile matter contents as industrial indicators to identify graphite,but unable to differentiate anthracite and graphite accurately.On this account,combined present coal measures graphite industrial indices differentiation in our country with latest research achievements from the“Fujian Province Coal Measures Graphite Hosting Pattern and Resource Assessment”project,try to use fixed carbon and volatile matter contents as the basic indices to differentiate anthracite and coal measures(cryptocrystalline)graphite,take graphite carbon layer interval d 002 and Raman spectral parameters R 2 as precise indices established coal measures graphite identification system,so as to scientifically assess and use coal measures graphite resources. |
