摘要(Abstract)：

湘中石炭系测水组是华南早石炭世最有价值的煤系之一。通过对测水组煤系等沉积特征的综合分析,研究了本区控煤因素和聚煤规律;结合矿山开发现状,着重对金竹山、渣渡等老矿区进行煤炭资源预测。研究结果表明:湘中次级构造单元的隆起和坳陷直接控制了煤系发育和含煤性,富煤区往往位于向斜仰起端和平缓翼部位;古陆前缘坳陷中泻湖及潮坪环境是煤层发育的有利场所;含煤性与煤系厚度一般呈正相关关系,含煤性好的地区砂泥岩比值一般为0.5～1;预测金竹山矿区深部和渣渡矿区南段利民矿深部及两翼煤炭资源储量共372.98 Mt。总之,老矿区中深部及外围煤炭资源前景乐观,可以作为重点勘查靶区。
Carboniferous Ceshui Formation in Central Hu′nan is one of the most valuable coal measures of Early Carboniferous in South China.Through comprehensive analysis of the sedimentary features of coal measures in Ceshui Formation,the paper studied the coal-controlling factors and the regularities of coal accumulation.In combination with the actual situation of present coal mining,the coal resources have been predicted emphatically in the old mining areas Zhadu and Jinzhushan.The study results indicated that uplift and depression of sub-tectonic units in Central Hunan have directly controlled the development of coal measures and coal-bearing properties,coal-enriched areas are often located in the uplifting side and gentle wing of synclines.Lagoon and tidal flat environments in depression of the leading edge of the paleocontinent were favorable for coal seam development.Coal-bearing properties and thickness of coal measures are generally positively correlated.In good coal-bearing areas,sandstone and mudstone ratio is generally within the range of 1/2 to 1.It was predicted that there are 372.98 Mt of coal resources in deep Jinzhushan mining area and deep Limin mine at southern Zhadu mining area as well as their two wings.The results show that the coal resources at the deep and middle deep parts in the mining areas and their surrounding areas have optimistic prospects,can be used as the key exploration target.
