Mining Engineering: How depth, geometry, grade and ground decide the mining method — and why the choice is economic before it is technical; Benches, berms, overall slope angle, and why the waste you must move decides the pit more than the ore; Room-and-pillar,.
All 7 articles are published. Each one states what it needs, what can be concluded with it, and what cannot — and every one stays marked DRAFT until it has had independent geological review.
- 1. Open pit or underground publishedHow depth, geometry, grade and ground decide the mining method — and why the choice is economic before it is technical.
- 2. Pit geometry and stripping ratio publishedBenches, berms, overall slope angle, and why the waste you must move decides the pit more than the ore.
- 3. Underground mining methods publishedRoom-and-pillar, sublevel stoping, cut-and-fill, block and sublevel caving — the geometry each one needs.
- 4. Dilution and ore loss publishedWhy the mined grade is never the modelled grade, where dilution comes from, and how it is estimated honestly.
- 5. Rock mass and ground behaviour publishedIntact rock versus rock mass, discontinuities, RMR and Q, and the failure mechanisms that control stability.
- 6. Mine planning and scheduling publishedFrom block model to pit shell to schedule: what the optimiser maximises and what it silently assumes.
- 7. Mineral processing and recovery publishedComminution, liberation, flotation, leaching and gravity — and why recovery is a property of the mineral, not of the grade.
