Sub-level open stoping - QueensMineDesignWiki

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.

Definition of sublevel stoping - mindat glossary

Definition of sublevel stoping. i. In this mining method, the ore is excavated in open stopes, retreating from one end of the stope toward the other. The orebody is developed first by a series of sublevel drifts above the main haulage level. The sublevels are connected by a starting raise at one end of the stope and by a passageway raise for entrance to them and the stope face at the other end

Stoping - Wikipedia

SummaryTimbered-stope systemsOverviewOpen-stope systemsShrinkage stopingLong hole stoping

Stull stoping is a form of stoping used in hardrock mining that uses systematic or random timbering ("stulls") placed between the foot and hanging wall of the vein. The method requires that the hanging wall and often the footwall be of competent rock as the stulls provide the only artificial support. This type of stope has been used up to a depth of 3,500 feet (1,077 m) and at intervals up to 12 feet (3.7 m) wide. The 1893 mining disaster at Dolcoath minein Cornwall was caused by failure of the stulls holding up a huge

Underground mining (hard rock) - Wikipedia

Shrinkage stoping is a short-hole mining method which is suitable for steeply dipping orebodies. This method is similar to cut and fill mining with the exception that after being blasted, broken ore is left in the stope where it is used to support the surrounding rock and as a platform from which to . Only enough ore is removed from the
