Abstract
In order to understand the movement characteristics and the structure of roof at longwall face,the deformation characteristics and the structure of roof at longwall face were investigated using numerical simulation and theoretical analysis.The results show that the bearing structure in the overburden strata can still be formed under a shallow buried depth and the structure can protect the support.The conclusion was verified through the observation data.The paper presents the new findings for the roof structure and movement characteristics at longwall face with a shallow depth.
