    Ore Body CharacteristicsAdvantagesDisadvantagesMine DevelopmentGround SupportProduction RateEquipmentMaterial HandlingSublevel Caving LayoutSublevel Caving Safety- A competent rock mass allows for more drilling and blasting within each stope. This provides good fragmentation and leaves the caving above very coarse. This results in blasted material finer than the cave, making distinction between ore and waste easier. • Steeply dipping orebody: - Keeps the low grade waste further away from the current draw points, keeps dilution low. •Massive deposit: - Need a large footprint to minimize dilutioSee more on minewiki.engineering.queensu.ca
  • Sub-level caving success at Syama - Mining Magazine

    Sub-level caving is an advanced and highly efficient low-cost bulk underground mining method that provides early access to ore. Mining commences at the top of the deposit and develops downwards. Ore is mined from sub-evels spaced at regular intervals throughout the deposit. A series of ring patterns are drilled and blasted from each sub-level, and broken ore is extracted out after each blast ...

  • Sub-level open stoping - QueensMineDesignWiki

    BackgroundDesignDevelopmentEquipmentSupportSafetyEconomicsReferencesDescriptionThis method is usually considered as an alternate to sublevel caving when a lower dilution method is needed and where the rock is fairly competent. The production for a mine using sublevel stoping can range from 15- 40 tons/employee-shift, while one stope can produce greater than 25000 tons per montOrebody RequirementsOre bodies that are ideal for sublevel stoping are very tall and have a medium to narrow width, but can have an extensive length. The ideal width of the orebody should be greater than 6 meters but less than 30 meters. Most of the time this type of orebody has a dip greater than the angle of repose of the ore, oAdvantages1. Dilution may occur but 100% of the ore is usually recovered from the stope. 2. Pillars that are left in place can be removed once adjacent stopes have been backfilled. 3. Large scale blasting lowers costs. 4. Stopes may be drilled before any blasting, to allow for larger and more efficient blasts. 5. The early devSee more on minewiki.engineering.queensu.ca

    Large, modern-day caving projects typically report total CAPEX of anywhere from US$500 million to in excess of US$10 billion for ‘mega-caves’. However, operating expenditure (OPEX) for block or panel caves is much lower than for other underground methods and is comparable to open pit mining costs. Typical OPEX is in the order of US$10-20/t.

    2020-04-14  Sublevel caving is often used in conjunction with surface mining. Sublevel caving extracts the ore via sublevels, which are developed in the orebody at regular vertical spacing. Each sublevel features systematic layout with parallel drifts, along or across the orebody. In the wide orebody, sublevel drifts start from the footwall drive, to continue across, reaching the hanging wall. In the ...
