摘　　要：基于湘西北湖田溶地区地质调查与理论研究,采用实验测试、元素分析及数学分析等方法研究了区内下寒武统牛蹄塘组含钒石煤的地质特征及成矿环境。研究结果表明,区内下寒武统牛蹄塘组下段为主要的石煤赋存层位,石煤的厚度介于5.35～31.2 m,平均16.19 m,发育基本稳定;石煤平均发热量仅为4.04 MJ/kg,与灰分、挥发分、水分及硫含量均有关系;伴生钒矿V2O5最高品位可达1.2%,达到工业品位,可与石煤共采;含钒石煤为缺氧还原环境海底热液作用下形成。Based on geological survey and the study in Hutianrong area in northwestern Hunan, use such methods as experimental test, element analysis and mathematical analysis studied the vanadium contained stone coal geological characteristics and its mineralization environment in lower cambrian Niutitang formation. The study found that stone coal mainly distributed in lower member, Niutitang formation, lower series, lower cambrian, with thickness 5.35 to 31.2 m, average 16.19 m, basically stable development;calorific value was 4.04 MJ/kg, had relationship with ash, vdaf, water, sulfur of stone coal;the highest grade of V2O5 was 1.2%, achieved the industrial grade, could be used together with stone coal mining;vanadium contained stone coal was formation under anoxic reducing environment accompany with effective of seafloor hydrothermal.
