Combining with the geological conditions and the failure characteristics of the 2103 roadway in the second panel in Chengzhuang Coal Mine,a reinforcing mode of composite grouting with cement slurry and unsaturated polyester and grouted pre-stressed anchor cable supporting for roadway’s surrounding rock was put forward. The numerical simulation showed that the grouting could greatly improve the supp orting effect of pre-stressed anchor cable.The cement slurry filled into larger cracks,the chemical pulp bonded smaller ones.With designing rational grouting p ressure,the cracks in the surrounding rock was expanded,and the grouting pre-pr essure was produced by retraction after grouting.This reinforcing mode can effec tively control the strong deformation of the roadway with dynamic pressures.
