Abstract: The retaining roadway along the goaf is supported by combined support of anchor bolts and cables and grouting reinforcement.
The high support resistance and the improvement of surrounding rock bearing capacity effectively control the problem
of large surrounding rock deformation. Moreover, the adopted support scheme reduces the serious problems of bending and sinking
in the early and middle stages of surrounding rock deformation and makes the surrounding rock of the roadway in a stable state.

Key words: combined support of anchor bolts and cables; grouting reinforcement; gob-side entry retaining; surrounding rock
deformation
