- Second semester 2017 (Day)
This unit will address the mechanics and practical applications and current technologies in rock fragmentation through drilling and blasting. The impact on blast behaviour of rock mass properties, structure and discontinuities and rock breakage and fragmentation will be addressed. Drilling and blasting techniques will be explored in relation to design, safety, security, environmental impacts and relevant legislation. This will be done in the context of mine-to-mill.
At the conclusion of this unit, students will be able to:
- Comprehend and explain the contribution of rock breakage to the mining process
- Comprehend and explain the various methods of rock breakage
- Apply and implement appropriate methods of drilling and rock breakage for given in-situ rock conditions
- Apply fundamental principles to the design and selection of safe and efficient blasting to:
- Design blasts to achieve particular outcomes
- Manage and control blast damage and environmental impacts
- Evaluate productivity and economics
- Analyse requirements for the security, storage and handling of explosives and recommend and justify safe handling systems
- Communicate effectively as an individual or part of a team to colleagues and the community
