摘要
东光煤矿含煤地层为龙潭组,含煤层数多,煤层厚度变化大。根据矿区地质资料及测井成果,采用标志层法、古生物法,测井曲线特征对比法、煤质分析等方法对煤层进行综合对比。准确判定了该区可采煤层6煤、14煤、16煤、21煤、23煤、27煤及其相应标志层B3、B4、B6、辅1、辅2、B7、B9,的位置关系,并在此基础上对各煤层厚度的变化趋势进行了定性解释。
The coal-bearing strata in the Dongguang eoalmine belong to Longtan Formation; contain many coal seams with variable thickness. Based on mine area geological data and well logging results, comprehensively correlated coal seams by methods of marker bed, paleontology, logging trace characteristics and coal quality etc. The horizon relations between mineable coal seams Nos.6, 14, 16, 21, 23 and 27, as well as corresponding marker beds Nos.B3, B4, B6, F1, F2, B7 and B9, on this basis, qualitatively interpreted thickness variation trends of each coal seam.
