Underground Mining of Metalliferous Deposits
Prof. Bibhuti Bhusan Mandal and Prof. Kaushik Dey · IIT Kharagpur
About
Underground Metal Mining (Underground mining of metalliferous deposits) -
(i) Introduction to Metalliferous mineral deposits, exploration, deposit characterizations, understanding cut-off grade, dilution, optimum recovery, financial impacts etc.
(ii) Access to mineral deposits: Types of access and selection criteria, location, size and shape; Adits, Inclines, Declines, Shafts; Conventional and special methods of excavation, lining, deepening and widening.
(iii) Lateral and inclined development of openings to mineral blocks; Levels, Drive, Drift, Crosscuts, Raising and Winzing etc.
(iv) Classification and choice of stoping methods, Methods of stoping: open stoping, supported stoping – breast, underhand and overhand stoping, shrinkage stoping, cut and fill stoping method, sub-level stoping; Introduction to caving methods: top slicing, sub-level caving, block caving; Stope mechanization and level interval.
(v) Support: Rock bolting, Cable Bolting, Pillar Design; Backfilling: preparation, transportation of mill tailings and filling operation.
(vi) Safety, Environmental issues and Case studies.
INTENDED AUDIENCE : Students of Mining Engineering, Mining Machinery, Mineral Processing,Earth Sciences (Geology/geophysics etc.)
INDUSTRIES SUPPORT : All the Mining and allied industries
