1. Study of the influence of interactive draw upon drawpoint spacing in block and sublevel caving mines
Sammanfattning : .... LÄS MER
2. Caving mechanisms for a non-daylighting orebody
Sammanfattning : The sublevel caving mining method is a mass production method with potentially very low operational costs. The success of this method is dependent on, among other factors, the cavability of the orebody and the overlying rock mass. LÄS MER
3. 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
4. Effects of confinement and initiation delay on fragmentation and waste rock compaction : Results from small scale tests
Sammanfattning : Sub-level caving (SLC) is classified as a mass mining method and there is an increasing interest in its application worldwide and in a very wide range of geotechnical environments. Design of sub-level blasting rounds and optimization has become more important now when the sizes of the blasting rings have become larger. LÄS MER
