ANALYSIS OF SEISMICITY IN MINES AND DEVELOPMENT OF RE-ENTRY PROTOCOLS
Following a large seismic event in hard rock mines, there is a short-term increase in aftershock activity, which over time decays to background levels. During this time of elevated seismic activity the risk of aftershocks ...
An Economic and Financial Deconstruction of the Commodity Streaming Business Model
The objective of this thesis is to evaluate the viability of the commodity streaming business model, both as a standalone enterprise and as a financing service for exploration and mining companies. A silver streaming ...
CUT-OFF GRADE STRATEGY: ANALYSIS FOR DOMINGA PROJECT
Cut-off grade is a concept used in the mining industry to decide whether to consider the material from the mine as ore or waste. The decision of the specific cut-off grade used in a mine should be periodically evaluated ...
An Investigation of Diggability and Other Digging Effort Related Metrics for Cable Shovels at Multiple Mines
A performance monitoring study was conducted aboard electric cable shovels at three different open-pit mines for the purposes of quantifying digging effort. A comparative analysis of public domain diggability metrics was ...
Timing Effects on Fragmentation by Blasting
Rock fragmentation has always been an indicator for the efficiency of blasts in mines. Several suggestions have been made by blast operators and specialists to improve the rock fracturing mechanisms in order to obtain ...

Small Scale Study of the Role of The Muckpile in the Blasting Fumes of Commercial Explosives
Blasting fumes are an important safety topic for the mining industry because toxic fumes are generated by the detonation of explosives. Prediction of the amount and concentration of blasting fumes is important for underground ...
Data Quality of Fleet Management Systems in Open Pit Mining: Issues and Impacts on Key Performance Indicators for Haul Truck Fleets
Open pit mining operations typically rely upon data from a Fleet Management Systems (FMS) in order to calculate Key Performance Indicators (KPI’s). For production and maintenance planning and reporting purposes, these KPI’s ...
An Investigation of Selective Galena Recovery Following Its Depression
It is challenging to obtain a final lead concentrate from copper-lead-zinc ores due to the complex mineralogy of the ore and the similar flotation behaviour of minerals within the ore. This study was carried out to investigate ...
