Abstract: Taking the gob-side entry retaining in Zhujiadian Coal Mine as the research object, this paper analyzes the deformation mechanism of the surrounding rock of the gob-side entry retaining in the mine by combining theoretical analysis and field tests.In combination with the geological and mining conditions, targeted surrounding rock control technologies are proposed, including roof cutting and pressure relief, constant resistance and large deformation anchor cables, roadside filling, coal wall reinforcement, concrete pillar auxiliary support and other technical means.Through on-site monitoring and engineering practice, the effectiveness of the adopted technologies has been verified.The on-site monitoring results show that compared with the original support scheme, the displacement amount of the roof and floor of the working face has decreased by 36%,and the convergence amount of the two sides has decreased by 52%.The axial force of the reinforced anchor cable is stably maintained at 193.5 kN,and the anchor cable has a large bearing space.The filling body combined with the concrete support has significantly improved the bearing capacity.
