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. Working in underground offices
Sammanfattning : The present doctoral dissertation discusses Japanese office employees' psychological reactions to their underground work environment. Studies I and III were methodological in nature and aimed at developing and validating instruments to be used in the empirical studies. 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. 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
5. Analysis of underground concrete pipelines subjected to seismic high-frequency loads
Sammanfattning : Buried pipelines are tubular structures that are used for transportation of important liquid materials and gas in order to provide safety for human life. During an earthquake, imposed loads from soil deformations on concrete pipelines may cause severe damages, possibly causing disturbance in vital systems, such as cooling of nuclear power facilities.
