The Shape of Hard Rock Mining in the 21st Century ...

1985-7-1  Hard rock underground mining has been wedded to the drill-blast method of breaking rock. Current practice and technology have focused on greater efficiencies in the blasting and handling of ore, on the basis that the lower costs that come with larger scale operations compensate for the waste dilution associated with the bulk methods.

Fire behavior of mining vehicles in underground hard rock ...

2017-7-1  A better knowledge about the fire behavior of vehicles in underground hard rock mines is therefore needed. During the analysis the direction and flow rate of the ventilation in a drift was found to have a significant impact on the fire behavior, causing for example flame tilt with rapid fire spread.

Production Schedule Optimisation in Underground Hard

There are presently no suitable underground mine production scheduling optimisation models available for application to sublevel stope mining. Scheduling underground production for maximum return is therefore still a manual process, which generally involves scheduling production from the next available highest cash flow stope within the operational constraints of the project.
