Continuous surface mining projects are dynamic and quite complex. They are characterized by geological and spatial variability and several stochastic parameters that affect initial planning and final design. In strategic mine planning and operations management of such projects, the location of the distribution point of the belt conveyor system (BCDP) is of high importance as it directly influen...

Since its closure in 1995 and the subsequent accident happened in 1998, the Aznalcóllar mine pit has been used as a disposal site for diverse metal-rich materials removed during the rehabilitation of polluted areas along the Guadiamar river and around the former ore processing facilities. At present, the mine pit is partly flooded and contains a highly acidic (pH 2.7) pit lake with ~6 Hm of met...

“We don’t need another consultant or business professor preaching to us that we need to develop our salespeople... Instead, we need to know what the best training methods are and why we should use them... So, if you cannot explain specifically to me what our sales managers need to do to improve their training efforts and why we should even invest the effort to change, then don’t waste your time...

The IFRS Interpretations Committee (the Committee) has finally issued its Interpretation on accounting for waste removal costs IFRIC Interpretation 20 – Stripping Costs in the Production Phase of a Surface Mine (the Interpretation). This Interpretation is effective for annual periods beginning on or after 1 January 2013. Entities will be required to apply its requirements for production phase s...

Driverless haulage trucks have recently been developed for open pit mines. To predict the benefits of an Autonomous Haulage System (AHS), a deterministic/stochastic model has been created to compare AHS to a manual system by estimating benchmarked Key Performance Indicators (KPIs) such as productivity, safety, breakdown frequencies, maintenance and labor costs, fuel consumption, tire wear, and ...
