Abstract：In light of the weak bearing capacity of the coal body and the complexity of controlling the surrounding rock in the waist lane of the thick coal seam in Hongqingliang coal mine,a support scheme was proposed.This scheme involved the implementation of an Anchor mesh cable in conjunc-tion with an Anchor cable and a steel belt.The selection of this scheme was informed by a thorough a-nalysis of the coal body's characteristics.seam and the stability of the surrounding rock,and simula-ted the effect of the support before and after the roadway using the FLAC3D software.The findings re-vealed that this scheme can effectively control the surrounding rock of the roadway in the thick coal seam and improve the deformation of the surrounding rock of the roadway.The programme was found to be capable of effectively controlling the deformation of the surrounding rock of thick coal seams and improving the bearing capacity of the coal body.The on-site monitoring results indicate that the"An-chor net cable+Anchor cable steel belt"support programme has achieved the expected outcomes,with the deformation of the surrounding rock exhibiting stability after 120 days and the roadway meet-ing the design requirements for utilisation.
