摘　　要：潘西煤矿区内二叠系下统山西组3煤层结构复杂,煤层赋存状态不稳定,对矿井实际生产影响较大。根据矿井实际生产中所揭露3煤层煤层厚度、煤层结构、煤岩类型、顶(底)板岩性、煤质及岩浆岩侵入、地质构造特征等地质现象,分析矿井主采煤层3煤层结构、赋存发育规律,为矿井采区的生产开拓布置、煤层开采等提供技术基础数据。The structure of coal seam No. 3 of Shanxi Formation of Lower Permian in Panxi Coal Mine Area is complex, and the occurrence state of coal seam is unstable, which has a great influence on the actual production of the mine. According to the geological phenomena such as coal seam thickness, coal seam structure, coal rock type, roof(bottom) slab lithology, coal quality and magmatic intrusion, and geological structure characteristics revealed in the actual production of the mine, the structure, occurrence and development law of the third coal seam in the main mining coal seam of the mine are analyzed, which provides technical basic data for production layout and coal seam mining in mining area.
