Grouting reinforcement can effectively improve the state of roadway fractured surrounding rock. According the fact that the grouting effect of 213 roadway of HUOPU coal mining is not ideal when water cement ratio was 2∶1,the influencing factors of grouting were analyses, and the reasonable water cement radio 0.8 was obtained by proportioning test. Roof convergence and two side deformation were monitoring, the result shows that: when water cement ratio is 0.8,and depth of grouting hole is 4 meter, the grouting quality is more ideal, and the state of fractured surround rock of 213 roadway is greatly improved.
