1. Improved understanding of sublevel blasting : Determination of the extent of the compacted zone, its properties and the effects on caving
Sammanfattning : Sublevel caving (SLC) is a mass mining method relying on the flowability of the blasted material. The ore is blasted in slices against caved material which is mainly waste rock. The result of the confined blast is greatly influenced by the interaction between the blasted material and the caved material. LÄS MER
2. Draw control strategy for sublevel caving mines : A probabilistic approach
Sammanfattning : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. LÄS MER

5. Hanging wall stability of sublevel caving mines in Sweden
Sammanfattning : Mining with sublevel caving implies a drastic destruction of the ground surface in the area conforming the hanging wall of the mine. The extent of this affected zone is of little importance in unpopulated areas, but becomes of utmost economic significance when there are mine installations or a town site located on it. LÄS MER
