Abstract: This paper analyzed failure mechanism of return air roadway in the 1304 working face, adopted "combined support
with bolt wire cable and shotcrete" to repair and reinforce some sections of roadway combined with field condition. The results
showed that the implementation of scheme can effectively control the deformation and destruction of roadway and have good
supporting effect.
