| Popis: | The selection of the adequate mining method is the cornerstone for mine planning and design. This selection depends on geological, geotechnical, economical, and environmental parameters. This paper’s main purpose is to select the most appropriate mining method for the south body of Boukhadra underground mine (NE Algeria). To do so, a new study is needed taking into account the lithofacies variation between different stages (levels) of exploitation, and British Columbia University (UBC) method is practical here. The results have shown that the cut and fill, sublevel stoping, sublevel caving, and block caving methods are technically feasible. However, the economic and environmental parameters have favored the sublevel stoping method. This method was subjected to a stope resizing analysis using the stability graph empirical method. The finite element calculation code Plaxis 2D and 3D was used in order to validate the results of the empirical method. |
