1. Towards understanding breakage and flow in sublevel caving (SLC) : Development of new measurement techniques and results from full-scale tests
Abstract : Blast function, fragmentation and gravity flow are core elements for sublevel caving (SLC). For the ore recovery to be as high and the waste rock dilution as low as possible all three elements have to work as planned. READ MORE

2. Assessment of rock mass quality and its effects on charge ability using drill monitoring technique
Abstract : 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. READ MORE

3. Load-Haul-Dump operations in underground mines
Abstract : The research presented in this thesis addresses several aspects of loading operations inunderground mines, in particular tools and equipment selection. It also addresses the flexibilityof the fleet when subject to substantial disturbances, such as ore pass loss, and proposes integration of the scheduling system with discrete event simulation.

5. Effects of confinement and initiation delay on fragmentation and waste rock compaction : Results from small scale tests
Abstract : 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. READ MORE
