6. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting
Abstract : 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. READ MORE

7. Role of Fragmentation at the Production Level of a Sublevel Caving Operation
Abstract : 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. READ MORE

8. Draw control strategy for sublevel caving mines : A probabilistic approach
Abstract : 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. READ MORE

9. Draw control strategy for sublevel caving mines : A holistic approach
Abstract : 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. READ MORE

10. Analysis of Excavation Damage, Rock Mass Characterisation and Rock Support Design using Drilling Monitoring
Abstract : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. READ MORE
