In most mining operations the insitu ore is separated from the waste rock and is subjected to a series of breakage and separation processes to convert it into a valuable product. Blasting is the first step in that breakage and separation and impacts entire mine to mill process chain. Still in most operations, blasting is viewed as a sub-process of mining and blasts are often sub optimally designed to satisfy the needs of mining operations (such as load and haul), geotechnical and safety risks rather than enhancing the value all downstream processes.
Over the past twenty five years, Dr Kanchibotla has demonstrated the critical role of blast outcomes on mine-to-mill process optimisation. He has developed several advanced blasting techniques and applied them at many large mining operations around the world to improve throughput and profitability.
This workshop explains the fundamentals of explosive properties, rock mass properties and interaction between the during blasting process. It also discusses the importance of blast outcomes in enhancing a mining operation value without increasing the risk. Designing and implementation advanced blasting techniques will be discussed in an interactive manner using practical problem solving exercises. The workshop discusses the following topics:
- Explosives and Delivery Systems.
- Influence of Geology and Rock Mass Characteristics on Blast Outcomes.
- Explosive rock interaction during blasting.
- Key blasting outcomes and their impact on downstream processes efficiency.
- Models and tools to predict blast fragmentation, ore loss, dilution and damage.
- Measurement of blast outcomes.
This workshop is designed to explain the principles and practical application of Advanced Blasting strategies with an objective to improve the overall Mine to Mill Process efficiency. This workshop is aimed for drill and blast engineers, mine superintendents, ore control geologists, geo technical engineers, metallurgists, mine managers, concentrator managers, general managers, asset optimization managers and business improvement managers - personnel responsible to improve the overall productivity of operations.
