Due to the poor lithology and strong fluidity, the deformation of the support in the late stage of the roadway threatening the safety of the underground construction, the object of this study is to design a transportation roadway with a length of 1 300 m and a depth of 5 00 m, and analyze the surrounding rock deformation, the waist line movement and the floor heave seriously during the roadway process, and use the high-strength preload anchor to carry out the two rework support test. The pre tightening force of anchor and auxiliary cable was tested in the test roadway, and compared with the supporting force of roadway surrounding rock deformation, it was concluded that the high strength pre load anchor bolting scheme can achieve the controllability of roadway deformation. The test results showed that the roof subsidence of the roadway was the most large 39 mm, the maximum value of the two help is 163 mm, and the bottom floor basically without change. This proved that the high strength pre tight anchor bolt support can meet the demand of the roadway, providing the value of popularization and application under similar condition.
