| Abstract: |
| Reasonable mining methods directly affect the overall safety of mines and the economic indicators of production technology. Aiming at the high value ore body under the mudstone overburden of the roof of Maochang gently inclined bauxite mine, this paper studied the optimization of safe and efficient mining method, and proposed several suitable mining methods. Through the comparative analysis of multiple technical and economic indicators, a two-step strip cemented backfilling method with high safety and significant economic benefits was finally preferred. This paper can provide better reference for mines with similar complicated geological conditions at home and abroad. |
