Abstract：The end of the working face in the shallow buried depth and close distance environment mostly uses the traditional single column combined with I-beam as the main support measure. However, a large number of practices show that this support measure lacks strength, and the shrinkage deformation coefficient of roadway is high, which affects the roof control in the process of working face withdrawal, resulting in a series of problems of local high caving. Based on this, taking Shaping Coal Industry as an example, this paper explores the support technology of withdrawal channel in close-distance coal seam.
