淮南复向斜南北两翼分别为舜耕山-八公山推覆构造和明龙山-上窑山推覆构造。依据区内岩石力学物性参数和重力、地震等地球物理场分析,地球物理场特征和构造格架是一致的。为此笔者建立该区综合地质-地球物理模型,在此基础上提出淮南复向斜区和周邻、特别是逆冲推覆构造带下是本区石炭、二叠系煤、煤成气的主要靶区。

The nappe structures of the Shungengshan-Bagongshan and the Minglongshan- Shangyaoshan belts developed respectively along north and south flanks of the Huainan Synclinorium. The geophysical analysis on the lithomechanics,seism and gravity in the area have suggested that the geophysical field characters coincide with the tectonic regime. Based on the above analysis,the authors of this paper established comprehensive geological-geophysical models and furthermore,proposed that the Permo-Carboniferous coal seams and the coal derived gas,especially those beneath the thrust belts are main prospecting plays for the Huainan Synclinorium and its adjacert areas.
