| 摘 要： | 淮南煤田的含煤地层为石炭系和二叠系，主要构造格架为一近东西向展布的“对冲式断-褶构造带”。该带可分为3个次级构造带：南部“八公山-舜耕山构造带”，为一由南向北逆冲的推覆构造带；北部“明龙山-上窑构造带”，是位于淮南煤田北缘由北向南逆冲的推覆构造带；中间为“淮南扇形复向斜带”，构成淮南煤田的主体。淮南对冲式断-褶构造带是印支期华北板块与扬子板块碰撞造山的产物，是大别山北侧薄皮推覆构造前锋带和外缘带的主体，主要沿结晶基底与盖层的接触界面滑动。淮南煤田发育在“淮南扇形复向斜带”中，南北向的强烈挤压、对冲使得位于其中的含煤地层遭受错断、牵引而弯曲，直至倒转，严格控制着淮南煤田的构造格架和几何学形态。

| Abstract: | In Huainan coalfield the coal-bearing series are Carbonifererous and Permian. Main structural framework is an EW ramp fault-fold structural belt. This structural belt consists of three secondary order structural belts. The southern Bagongshan-Shungengshan structural belt is an over-thrust belt with S-N direction, and is a model of imbricate fault, it is consisted of thrust faults and thrust sheet. Minglongshan-Shangyao structural belt in north is other over-thrust belt with N-S direction. Fan synclinorium is their middle part. Huainan ramp fault-fold structural belt is the main body of Huaina coalfield, is an important part of foreland deformation belt in northern Dabieshan orogenic belt, it includes the thrust frond and autochthone of dabieshan deformation in its northern. Main slip plane is on the top of crystalline basement. The structural formwork of Huainan coalfield is taken by the pressure with SN direction in Indonisian period. |
