| Abstract: | Roof grouting reinforcement technique was used to prevent fault broken roof from falling. Mechanics characteristics of high water content grouting reinforcement material, reinforcement technology and parameters were also analyzed. Practical applications indicate that the falling of fault broken roof can be basically solved and good technical and economical benefits can also be obtained. |
