Abstract:

The coal resources are hosted mainly in the lower Carboniferous Ceshui formation, upper Permian Longtan formation, and secondly in lower Permian Liangshan coal-bearing formation, upper Triassic Zijiachong formation, and lower Jurassic Tanglong formation. According to the geology of coal resources, six coal fields are divided in Hunan province.By the end of 2007, the remaining coal resources are 3 154.9 million tons, about 17 years of mining life based on current production capacity. The exploration work is till in a low extent. This paper analyzes the regional geological structures, discusses the hosting features of coal resources, and presents the clues to coal potentials, which is favorable for the rational development and sustainable development of coal resources in Hunan province.

摘要：

湖南省煤炭资源主要赋存于下石炭统测水组、上二叠统龙潭组，其次为下二叠统梁山煤系、上三叠统紫家冲组、下侏罗统唐垅组。根据煤炭资源赋存特征，可划分6大煤田。截至2007年，湖南省保有煤炭资源量为31549亿t，全省生产、在建井可利用的保有资源量大约可开采17年，总体查明程度较低。通过对湖南省区域地质构造背景分析，掌握了煤炭资源赋存状况及赋存特点，理清了资源赋存规律，提出进一步找煤方向，以期使湖南省煤炭资源得到合理开发并持续发展。
