THE GEOLOGICAL—GEOPHYSICAL FIELD PROPERTIES OF THE HUAINAN SYNCLINORIUM AREA AND THE COAL/COAL DERIVED GAS PROSPECTING ANALYSIS

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.
