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 unsuppSee more on minewiki.engineering.queensu.ca

Jul 04, 2017· For sublevel stoping the ore body and walls should be strong enough to support open stoping. In this 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

Shrinkage stoping QueensMineDesignWiki
Shrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore. It is an overhand mining method that relies on broken ore being left in the stope to be used as the “working floor” and to support the walls.

Keeping up with caving Redpath Mining
Sub-level caving is typically used where the orebody has a smaller footprint and/ or more competent rock mass that prevents the continuous caving required for a block cave. Blasting of the entire orebody is required to produce a production ore flow. As sub-level caving uses a ‘top down’ approach, it requires less upfront capital
