1. 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
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
3. Role of Fragmentation at the Production Level of a Sublevel Caving Operation
Sammanfattning : This research was conducted to evaluate the association of rock fragmentation with different unit operations of a sublevel caving (SLC) production cycle. Drilling, charging, and blasting, as well as the nature of the rock mass, can affect the fragmentation observed at the drawpoints. LÄS MER
4. 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
5. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting
Sammanfattning : This research is carried out to better understand the nature of the rock mass and to have a better anticipation of rock fragmentation before blasting the rock mass. Current practices of assessing rock mass usually involve techniques that focus on the surface or outcrop of the rock mass such as scanline surveys, window surveys, photogrammetry and laser scanning etc. LÄS MER
