| 摘 要： | 叶溪育石煤是湖南省境内一种比较特殊的煤种,其赋矿层位属"下寒武统黑色含矿岩系",主要分布于寒武系下统小烟溪组下段,一般含石煤层3层,个别地段为4-5层。叶溪育石煤矿可采石煤主要为第二层,厚度4.98～9.18m,平均7.49m。该矿石煤分布面积大,层位稳定,连续性较好;原煤发热量3.52～10.23MJ/kg,灰分产率52.12%～74.32%,全硫平均含量1.56%,为中硫、高灰分、低发热量的劣质煤;煤系地层中同时含钒矿体Z1、Z2、Z3,呈似层状、透镜状产出,其中Z1矿体已达中型规模;根据稀土元素地球化学分析,含煤岩系形成于缺氧的还原环境,矿床成因属于生物地球化学沉积矿床。
