Combining geological investigation in Qinghai-Tibetan Plateau, coal geology was analyzed by remote sensing interpretation in Zaduo-Nangqian Area of Qinghai Province, regional tectonic structure was built, tectonic evolvement and coal-forming paleo-geographical environment were analyzed, and the control and influence of tectonics on coal accumulation and occurrence were discussed. The results showed that coal accumulation and occurrence were related to tectonic evolvement of Qiangtang Block, tectonic evolvement experienced 5 phases, regional tectonic activity was strong; coal was accumulated in the edge of depression and partly enriched; coal series were under strong erosion, complicated fracture and distortion.
