摘　　要：英安井田下含煤段含煤层数较多、岩性相近,煤层对比工作比较困难。在首采区补充勘探工作中,采用测井曲线对比方法,在确定K2标志段、22、26号煤标志层的基础上,将该区19号煤层顶板至23号煤层底板划分为上含煤亚段;23号煤层底板至30号煤层底板划分为下含煤亚段。并依据测井资料对19、20、20b、21、23、26、26a、30号等煤层的测井曲线异常特征进行了详细描述。该区依据测井曲线划分标志层段及含煤亚段的方法确定的煤层层位、层号,依据充分,达到煤层对比准确可靠的目的。The lower coal-bearing sector in the Yingan minefield contains many coal seams with similar lithologie characters and result in difficult coal seam correlation. In the initial winning district supplementary exploration, the logging trace correlation method was used, based on the K2 marker sector and marker beds of Nos.22 and 26 coal seams, defined the sector between No.19 coal roof to No.23 coal floor as the upper coal-bearlng subsector; No.23 coal floor to No.30 coal floor as the lower coal-bearing subsec.tor. According to logging data described logging traces anomalies of Nos,19, 20, 20b, 21, 23, 26, 26a and 30 coal seams in detail. The coal seam horizon and number defined by marker sector and coal-bearing subsector in terms of logging traces have good grounds, thus the objective of accurate and reliable coal seam correlation achieved.
