Abstract
In order to search for potential coal resources, by analysis of the surface and underground structure characteristics in the western part of Shiguai basin, it is considered that the front of Daqingshan thrust nappe should be F10 fault group.Surface Changhangou Formation etc.is allochthonous strata moved 3 km away from the south.The deep main coal-bearing strata, the first member of Wudanggou Formation, is almost not affected by nappe structures.The first member of Wudanggou Formation should be more southern than its surface position.Native coal seams not effected by nappe structures should exist below Permian strata in the south of the basin.
