Sublevel cave mining: unearthing new opportunities

Sublevel caving: unearthing new opportunities The known resource base for base metals is increasingly comprised of large scale, lowgrade deposits, situated at increasing depths where underground cave 1 mining methods are the only viable means of economic extraction In the spectrum of underground mining methods, caving methods are the lowest cost and most productiveCAMM & STEBBINS • SIMPLIFIED COST MODELS FOR UNDERGROUND MINE EVALUATION MONTANA TECH • MINING ENGINEERING DEPARTMENT • HANDBOOK • 4 Table 15 Sublevel Caving Model — Adit Entry (4,00014,000 t/d)44 Table 16 Sublevel Caving Model —Montana Tech Library Digital Commons @ Montana Tech

Block caving is an extreme case of sublevel caving in which instead of a back of ore 5 to 10 ft thick, one 50 ft thick is undermined and allowed to cave The methodSub level caving After more than 30 years of open pit mining, Rana Gruber AS started underground mining using the sublevel open stoping method at the Kvannevann Mine in 2000 The mining has been continuously improved and further developed to suit the difficult rock conditions in the area and to reduce operating costsThe mine Rana Gruber
