Please note! Course description is confirmed for two academic years (1.8.2018-31.7.2020), which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.
LEARNING OUTCOMES
After completion of this course the student:
- can describe the work cycles in rock excavation: Hauling and loading, crushing and rock reinforcement in hard rocks
- can characterize and explain rock excavation techniques: Drilling & blasting, mechanical excavation including TBM (tunnel boring machine technique) and underground mining methods
- can select suitable excavation methods and equipment for typical rock excavation projects
- can describe dewatering and ventilation for excavation works
- recognize the environmental effects related to rock excavation and blasting
- can apply the above knowledge to design simple rock excavations.
