Abstract：Through similar material simulation and computer numerical simulation, the breakage situation and the shape of main roof, the influence of different supports on roof activity and the relevant technique parameters for roadside packing were analyzed preliminarily. The results show that bolting with wire mesh and man-made roadside packing body with high strength are beneficial to the stability of gob-side entry, and the minimum width of packing zone and the minimum compressive strength of packing material were also provided.
