摘　　要：在马头岭井田新发现一个滑覆构造和白垩系红层掩盖下的二叠系上统龙潭组含煤构造。含煤地层分为上下两段,上段煤系一般厚250 m,由于断层破坏和白垩系红层剥蚀而保存不完整,主要可采煤层为6煤和7煤,煤层主要赋存于井田中部和南部。6号和7号煤层均为中灰、特低硫和中发热量的无烟煤。近南北向和北北东向的断裂为正断层,对马头岭赋煤向斜构造造成切割破坏,使西翼浅部煤层未能保存。A Permian Long＇tan Formation coal-bearing measures under detachment structure and Cretaceous red-bed was newly discovered in Matouling well field, Hunan province. The coal-bearing strata are divided into two members. The upper member coal measures are generally 250 m thick, incompletely preserved due to the faults and Cretaceous redbed denudation, in which No. 6 and 7 minable coal seams mainly occur in the middle and southern well field. No. 6 and 7 coal seams are anthracites characterized by low ash, super-low sulfur and medium caloric value. The SN and NNE faults are normal faults, which resulting in the dissection of coal-bearing measures in Matouling and the erosion of shallow coal seams in the west wing of syncline.
