ZDT17680/23/45 Type Face-end Split Hydraulic Support in Shanlang Coal Mine

In this paper, the equipment matching condition and mining method of 5# coal seam in Shanlang Coal Mine are introduced. The working resistance and composition form of the face-end support group are determined by the geological conditions of coal seam. The key technology, structure, application scope and technical parameters of the ZDT17680/23/45 type split face-end hydraulic support group are analyzed, and the electro-hydraulic control system is expounded. The use of the face-end hydraulic support group improves the deformation of the roof and improves the safety and efficiency of personnel production.
