摘要
为研究花岗岩体对煤层石墨化的影响,合理开发矿产资源,并指导同类型煤与石墨矿的找矿工作,通过系统采样测试,分析湖南涟邵煤田北段寒婆坳矿区煤与石墨矿的地质特征及分布范围,总结了煤系石墨化的成矿模式,确定了寒婆坳矿区距离岩体500~600 m的范围内,煤层石墨化程度高,预测寒婆矿区南部具有寻找大型石墨矿的潜力。
In order to determine the influence of the granitic rocks on coal graphitizing,to exploit mineral resourcesrationally,and to guide the prospecting work of the same kind of coal and graphite,we did sampling and testing,analyzed characteristics and distribution range of coal and graphite ore in Hanpoao mining area,summarized themetallogenic model of graphitizing in coal-bearing strata,determined that within500~600meters from the rockmass,the degree of coal graphitizing was high.It was predicted that there is a big potential to search for large-scalegraphite ore in the sourth of Hanpoao mining area.
