| Abstract: |
| Based on the investigation into the off balance mode and damage process of drifts in weak layered rock masses, the proposal of using cable bolt network for supporting of the drifts was put forward. A complete set of simply technologies for installation of the cable bolt network had been developed. The practical application had shown that the supporting method was effective and could produce a good economical profit. It is valuable for similar mines. |
