1. 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
2. Draw control strategy for sublevel caving mines : A holistic 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
3. 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
4. Waste rock content variations during gravity flow in sublevel caving : analysis of full-scale experiments and numerical simulations
Sammanfattning : När man lastar i en skivrasgruva så märker man ofta att gråbergshalten varierar på ett oregelbundet sätt. Denna variation är oönskad på grund av att den leder till gråbergsinblandning och malmförluster. LÄS MER
5. Assessment of rock mass quality and its effects on charge ability using drill monitoring technique
Sammanfattning : For an efficient mining operation, it is essential to have as much information as possible aboutthe ore to be excavated and the rock masses surrounding the ore. Geological information andthe content and distribution of extractable minerals, are central concerns for long term mineplanning. LÄS MER
