摘　　要：筠连矿区位于南方重要聚煤盆地的腹心地带,研究区位于筠连矿区的东端。本文主要从标志层、煤层本身特征、顶底板特征、岩性、岩相、结核及物性特征、煤的地球物理特征等方面入手,对研究区内二叠系上统宣威组上段煤层进行对比研究,在煤层对比过程中充分利用了煤、岩层物性组合等特征,重点对8^(-2)号煤层进行了深入剖析,提高了研究区8^(-2)等煤层对比的可靠性。通过对比确定8^(-1)、8^(-2)号煤层为全区可采的较稳定型煤层,7号煤层为大部分可采煤层较稳定型煤层,而9号煤层为局部可采煤层不稳定型煤层。The Junlian mining area is located in the core area of a major coal basin in the southern Sichuan,the study area is located in the eastern end of the Junlian mining area.This paper mainly focuses on the comparison of the Upper Permian Xuanwei Formation coal seams in the study area,including the marker layers,coal seams themselves,roof and floor characteristics,lithology,lithofacies,nodule and physical characteristics,and geophysical characteristics of coal.Based on the physical combination of coal and rock strata,this paper mainly analyse of the No.8^(-2) coal seam,which improves the reliability of the comparative study of the No.8^(-2) and other coal seams within the study area.It is considered that No.8^(-1) and No.8^(-2) coal seams are relatively stable and can be mined in the whole area,while the No.7 coal seam is relatively stable and can be mined in the most of the minable coal seams,and No.9 coal seam is unstable and can only be mined in certain parts.
