Sub-level open stoping

Description. This 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.

Hydraulic Impacts of Quarries and Gravel Pits

Water-Level Impacts. At all three sites, the quarry dewatering has altered the local ground-water hydrology. In essence, the quarries act as huge wells, lowering the water table in the aquifer. The impact of the dewatering at the Kraemer Quarry is shown in Figure 2. This lowering could affect Figure 2.
