摘要
依据钻探资料对黄陇侏罗纪煤田焦坪矿区转角勘查区含煤地层分布特征及可采煤层的分布与厚度进行了分析,认为转角勘查区含煤地层为中侏罗统延安组,主采煤层4-2号煤位于第一段。含煤地层及主采煤层的展布特征主要受三叠系顶板构造形态的控制,凹陷区延安组沉积厚度大,煤层较厚,隆起区煤层较薄或缺失。
Based on drilling data have carried out analysis on coal-bearing strata distribution features, mineable coal seams distribution and thickness variation in the Zhuanjiao exploration area, Jiaoping mine area, Huanglong Jurassic coalfield. The result has considered that the coal-bearing strata in Zhuanjiao exploration area belong to the Yan’an Formation; main mineable coal seam is coal No.4-2. The extending features of coal-bearing strata and main mineable coal seams are mainly controlled by Triassic top surface structural form. In the depression region, Yan’an Formation has large thickness with thicker coal seams; while in the uplift region has thinner coal seams or hiatus.
