Abstract: Thesynsedimentary fault in coal accumulating basin had a clear controlling role in the thickness, lithofacies and coal bearing nature of coal bearing series, and not only became a geological natural boundary but also had a direct effect on design of mining area and coal production because of its inheritable mobility after coal forming period.More recently,it is discovered that Hutoushan fault in Yuzhou coalfield is a large syndepositional inherited coal controlling structure. It was active during coal forming period. Based on the lithology,sedimentary thickness,coal accumulation,stratigraphic throw, disharmonic sedimentation at side of fault zone and result of trend surface analysis, it was proven to be a syndepositional fault in coal forming period. And after coal forming period posthumous movement took place again, with the evidences of bedrock dislocation and stratigraphic lacuna, control and reformation of landform and Cenozoicsedimentation, development of second order structures and traction of cool outcropping and features of fracture crushed zone,and so on. This discovery is very important and valuable both in theory and in practice, which gives guide lines for construction of mine,production,studying coalbed thickness,tectonics of Yuzhou coalfield and tectonicevolution of the north China plate.
