| Abstract: | The rock drilling holes in the main roof are arraged in the cutting holes and two roadways at the fully mechanized face with caving of roof with π type steel.By high-pressure water injection,the main roof collapse is scheduled to break off the crack before the initial pressure and cycle pressure,so as to reduce the occurred rate of the roof rock burst. |
