摘　　要：萍乡矿区位于萍乐坳陷带的西端,上三叠统安源组是该区主要含煤地层。成煤前的构造决定了沉积盆地的范围;可采煤层的赋存与同沉积构造密切相关,主要赋存于沉降幅度较大的同沉积向斜中及同沉积断层的下降盘;沉积后构造对煤层的控制作用主要表现在推覆构造对煤层的破坏和保存两方面。Based on the structural character of the whole sediment process in Anyuan Formation, Pingxiang area, Detailed studies show that the structures of the former coal-forming decide the area of sediment basin; the deposit of coal-bearing strata is connect with the syndepositional structures colsely, the mining coalbeds mostly deposit in the syndepositional synclines and in the dropped sides of the syndepositional fault. The reconstructin of the structure on the coalbeds represents that overthrust destroy and save the coalbeds after the coalbed being formed.
