摘要：

贵州省黔西煤矿区箐口煤矿含煤地层为晚二叠世龙潭组，为一套海陆交互相的滨海沼泽含煤碎屑岩沉积，为河流作用、潮汐作用双重控制下的过渡三角洲平原沉积环境。区内的8、9、12、15等可采、局部可采煤层具有各自的沉积微相。煤层对比主要采用标志层对比、物性特征对比、层间距、岩性组合特征对比、煤层特征对比、煤质特征对比等方法。通过对比分析，能准确区分箐口煤矿区的8、9、12、15等可采、局部可采煤层，并为箐口煤矿及其深部、邻近矿区勘查、矿山生产中的煤层提供可靠的对比依据和借鉴经验。

Abstract:

Coal-bearing sequence of Qingkou coal mine, which is situated in Qianxi coal mining area, Guizhou province, is hosted in the upper Permian Longtan formation, a set of shore marsh coal-bearing clastics, indicating a delta plain sediment under rivers and tides. Coal bed8, 9, 12, 15, minable or locally minable, have their own sedimentary microfacies. Comparison is focused on mark layer, physical features, interlayer space, lithology, coalbeds and coal quality. This paper distinguishes the coalbed 8, 9, 12 and 15 and offers references for deep and adjacent exploration and mining production.

Key words: features of rocks and coals, comparison, Qingkou coal mine
