Abstract：

In order to find the basic structure framework of Lianghuayuan field for coal resources exploration,the comprehensive and systematic analysis methods are performed by using detachment structure theoretical explana-tion and combined with borehole data,logging data,strata,coal seams and faults were compared.The obtained re-sults indicated that the previous conclusions of horst-graben structures are not correct.The new review is that a detachment structure is the main structure in Lianghuayuan field;two faults(F1 and F8) in eastern and western Li-anghuayuan field are the same concave arc-shaped detachment structure.The Lianghuayuan field is actually a whole mineral production area according to the regional geological background and dynamic feature.These obtained results are of more significance for expanding coal reserve calculation scale and avoiding resources loss.

Key Words： Huaibei coalfield,Lianghuayuan field,detachment structure,horst-graben structure
