湖南涟邵煤田北段寒婆坳矿区煤及石墨矿地质特征

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 resources rationally, 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 the metallogenic model of graphitizing in coal-bearing strata, determined that within 500~600 meters from the rock mass, the degree of coal graphitizing was high. It was predicted that there is a big potential to search for large-scale graphite ore in the sourth of Hanpoao mining area.
