摘要
黔北煤田南部化觉背斜地区地质构造简单,含煤地层为晚二叠系龙潭组,其含煤性稳定,区内可对比煤层8层(M5-M12),煤层结构简单,厚度较稳定-稳定,为薄-中厚无烟煤层。本文通过标志层、层间距、测井曲线、煤层自身特征等对比,各煤层的对比标志明显,依据充分,对比可靠,可作为区域煤矿地质勘查及开发利用的地质依据。
Huajue area is in the S part of north Guiznou coal field,the geological structure is simple.The coal-bearing strata belong to Late P Longtan Formation,coal-bearing quality stable.There are 8 comparable coal beds(M5-M12)in this area,coal bed structure simple,thickness stable,thin to middle thickness anthracite bed.In this paper,according to key horizon,bed interval,logging curve,coal bed feature correlation,coal bed correlation indices clear,reliable,which can be regarded as the geological foundation of regional coal deposit geological exploration and development utilization.
