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。
Coal-bearing strata of the Youkou coal mine in Qianxi coal mining area of Guizhou Province are late-Permian Longtan Formation, which is a suite of coastal briquette-coal-bearing clastic sediments of sea-land interaction facies, and is characterized by river action and tidal flat under the dual control of deltaic sediments surroundings. 8, 9, 12, 15, etc. can be taken in the area, the local recoverable seams have their own sedimentary microfacies. Comparison of the main coal seam using sign layer contrast, physical characteristics contrast, layer spacing, lithology combination of features, contrast of coal seams, coal quality features such as comparison method. Through comparative analysis, it can accurately distinguish 8, 9, 12, 15 and other recoverable and partially recoverable coal seams in Qiaokou coal mine area and provide reliable coal seams for the coal mine in Chengtou and its deep, adjacent mine exploration and mine production Comparison based on and learn from experience.
