Abstract: Aiming at the problem of serious deformation and fast deformation rate of the surrounding rock in the roadway of the return roadway of the 6307 working face of Dongtan Coal Mine of Yankuang Energy Group Co Ltd, the joint support technology of high pre-stressing strong anchor rods and cables was proposed. In order to verify that the optimised support scheme is effective, it is applied to the field practice. The results of field deformation monitoring show that: the deformation of the roadway peripheral rock tends to stabilise gradually after 50 d, the bottom drum of the peripheral rock is 248 mm, the two gangs move closer together is 124 mm, and the top plate sinks 64mm in 90d, the average increase in the amount of the bottom drum, the two gangs move closer together, and the top plate sinks 2.76 mm/d, 1.38 mm/d, and 0.71 mm/d respectively, the deformation of the peripheral rock in the roadway is relatively small, and the peripheral rock is relatively stable. The peripheral rock is more stable.
