  • Sub-level caving success at Syama Mining

    Syama is well suited to the sub-level caving mining method because of its scale, width, orientation and uniformity of grade. Unlike other bottom-up caving methods (block cave, panel cave) sub-level cave mining is a top-down method and therefore does not require large initial investments in mining infrastructure prior to commencement.

    BackgroundDesignDevelopmentEquipmentSupportSafetyEconomicsReferencesThis 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 month.In general this method is fairly safe as the mining tends to retreat away from previously mined or unsupported areas.
