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. Saving lives during major underground mining incidents : becoming prepared for a collaborative response
Sammanfattning : Background: Major incidents in underground mines are uncommon, but they can have severe consequences. In Sweden, the municipal rescue service and the regional emergency medical service (EMS) are dispatched to mining incidents, and together with the privately owned/state owned mineral and metalliferous mining company they perform a rescue operation.

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.
