摘　　要：福建省煤系石墨赋存于中二叠统童子岩组,是无烟煤受高温高压作用进一步变质而成,属隐晶质石墨。通过调查发现,福建省煤系石墨矿井、勘查区处于未开采或停采状态,开采矿区也多以煤炭开采的形式生产销售,造成资源浪费。为合理开发利用煤系石墨资源,采用d(002)(碳层间距)–R2(拉曼参数)模板鉴别煤系石墨并确定煤系石墨等级,结合区域构造的控制作用,划分了大田–漳平与永安–安溪石墨成矿区。在此基础上,综合实测数据和历年勘查资料分析,预测出永安长垇、永安下盖竹–甫弼–塘下洋、大田琼口–小溪洋–永安老鹰山、漳平可坑–乌石隔、漳平乌坑–华安福田5块煤系石墨资源远景区,其预测资源量8196万t,展现了良好的开发前景。针对目前煤系石墨资源开发利用现状,提出"规范煤系石墨资源开采秩序、建立煤与煤系石墨鉴别指标并设立明确的煤矿与石墨矿权规范、优化石墨资源开发利用体系等"系列建议,以实现福建石墨产业结构协调化、技术高度化、产品系列化和价值链完整化。The coal-based graphite of Fujian Province occurs in the coal-bearing strata of the Middle Permian Tongziyan Formation,is formed by the further metamorphism of the anthracite of the Tongziyan Formation under high temperature and pressure,and belongs to the aphanitic graphite.By investigating the distribution characteristics of coal-based graphite in Fujian Province,it was found that most of the coal-based graphite mines and exploration areas are in an unmined or stopped state,and production and sale in most mining areas are in the form of coal mining,causing resources waste.In order to rationally develop and use coal-based graphite resources,based on interlayer spacing d002 and Raman parameter R2,a classification of meta-anthracite of different rank and coal-based graphite is proposed.Combined with the control action of regional tectonics,Datian-Zhangping and Yong’an-Anxi metallogenic belts were divided.On the basis of measured data and the exploration data over the years,five prospective areas,i.e.,Yong’an-Chang’ao,Yong’an Xiagaizhu-Fubi-Tangxiayang,Datianqiongkou-Xiaoxiyang-Yong’an Eagle Mountain,Zhangping Kekeng-Wushige,Zhangping Wukeng-Hua’an Futian,were predicted.The predictive resources of coal-based graphite are 81.96 million tons,showing good development prospects.At the same time,series of suggestions were put forward to realize the coordination of Fujian graphite industrial structure,the advancement of technology,the serialization of products and the integrity of the value chain.
