Slice Drift Stoping with Roof Cut Caving and Its Application |
| |
Abstract: | Aimed at mining the steep thin orebody whose host rock was unstable, based on incorporating the advantages of short-hole shrinkage mining and sublevel caving and modifying this two mining method, the slice drift stoping with roof cut caving was designed, and was used in mining production boldly, with good technical-economical results. This is a beneficial trial to mine the steep thin orebody. |
