摘　　要：为深入了解水城县蟠龙镇长银煤矿煤层赋存特征,确定其可采煤层的连续性,采用标志层法辅以煤层层间距法、煤层本身特征、物性特征进行煤层对比。基于井田内标志层特征明显,含煤地层中部发育稳定的细砂岩、铁粉砂岩、C15煤层自身特征及底部拉斑玄武岩岩性特征,建立四个岩性标志层,标志层稳定,层间距较稳定,煤层特征清楚,物性特征明显,煤层对比可靠。To better understand the coal seam occurrence characteristics and determine the continuity of minable coal seams in Changyin Coal Mine,Panglong Town,Shuicheng County,the marker bed method and coal seam spacing method were used for coal seam correlation.Four lithological marker beds,including fine sandstone,iron siltstone,C15 coal seam,and underlying tholeiiticbasalt,were established based on their distinct features.These markers exhibit stable spacing,clear coal seam features,and distinct physical properties,ensuring reliable coal seam correlation.
