A CRITICAL REVIEW OF THE INPUTS TO LONG RANGE MINE PLANNING OF OPEN PIT PORPHYRY TYPE COPPER DEPOSITS
Long term planning is the process used by a mining organization to develop a strategic business plan. The plan describes how the ore is going to be extracted over the mine life. As such, it is routinely updated in order ...
Establishing Total Airflow Requirements for Underground Metal/Non-metal Mines based on the Diesel Equipment Fleet
Traditionally, ventilation requirements for modern, mechanized underground mines have been based upon the power of the diesel equipment fleet, with a multiplier (determined from empirical data collected and compiled over ...
Investigation of Fe(III)-As(III) bearing phases and their potential for arsenic disposal
Fe(III)-As(III) bearing precipitates have been successfully used for arsenic immobilization in copper smelter weak acid effluents. However, knowledge on their precise characteristics is very limited compared to ferric ...
Concept Design and Testing of a GPS-less System for Autonomous Shovel-Truck Spotting
Haul truck drivers frequently have difficulties spotting beside shovels. This is typically a combination of reduced visibility and poor mining conditions. Based on first-hand data collected from the Goldstrike Open Pit, ...
Reducing Haul Truck Fuel Consumption in Open Pit Mines by Strategic Changes to the Haulage Cycle
The goals of minimizing emissions and lowering operating costs by monitoring and controlling fuel efficiency have been a growing concern in the mining and construction industries. The largest single contributor of energy ...
HARD ROCKS UNDER HIGH STRAIN-RATE LOADING
Understanding the behavior of geomaterials under explosive loading is essential for several applications in the mining and oil industry. To date, the design of these applications is based almost solely on empirical equations ...
