1. Short-term Underground Mine Scheduling : Constraint Programming in an Industrial Application
Sammanfattning : The operational performance of an underground mine depends critically on how the production is scheduled. Increasingly advanced methods are used to create optimized long-term plans, and simultaneously the actual excavation is getting more and more automated. LÄS MER
2. Short-term Underground Mine Scheduling : An Industrial Application of Constraint Programming
Sammanfattning : The mining industry is facing a surge in automation in the pursuit of safe and profitable operations. As the excavation process is increasingly automated, today's mining companies seek to optimize the coordination of the now automated mining activities. LÄS MER
3. Design fires in underground hard rock mines
Sammanfattning : During several decades considerable research activities have been conducted with respect to fires in coal mines, but the research activities with respect to hard rock mines have been limited. As the hard rock mines are getting more complex the need for deeper understanding of fires in underground hard rock mines are getting more in demand. LÄS MER
4. Load-Haul-Dump operations in underground mines
Sammanfattning : 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. LÄS MER
5. Probabilistic Stability Analysis of Underground Mine Excavations
Sammanfattning : The creation of underground mine excavation disturbs the original state of the rock mass surrounding the excavation which often leads to instability of the excavation. This poses a threat to the safety of personnel and equipment in and around such excavations. LÄS MER
