Abstract
Coal is the main energy resource in Hunan province, through the exploitation for many years, shallow coal resources in exposed area have been mostly exhausted, therefore looking for new coal resources from hidden areas has become very urgent. Seeking coal in hidden areas is mainly to seek coal under old formation, structure and red beds, and seeking coal under "old formation and structures " mainly means using nappe structure theory to look for new coal resources. This article evolved a systematic and deep research on structural features of coal field in Hetian district of Baitutan mining area with the guide of the current tectonic geology theory and data that we already have for the purpose to deepen the knowledge of area structural and developing rules of coal field structues, toafford new thinking and extend new areas for the coal resources exploration and mine production by geology safeguard in this area. This research exposed tectonic structures in coal fields, proposed two possible structural modes, evaluated scientifically coal searching prospect and pointed out favorite districts for further exploration.
