Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines.

South Africa Coal Mining Cost Per Ton; Cost Models of Theoretical Mining Operations CostMine. This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material.

By using drones in mining, you produce cost-effective and accessible 3D reconstructions and surface models for areas to be blasted or drilled. These models help accurately analyze the area to be drilled and calculate the volume to be extracted post blasting. This data allows you to better manage resources such as the number of trucks needed.

Gold Heap Leach Cost Guide. The Gold Heap Leach Cost Guide is designed to bring all of the costs relevant to gold heap leaching into one quick reference. The guide provides estimators, engineers, investors and accounting professionals with cost estimating models for mining, heap construction and placing, gold recovery and reclamation.

Historically, mining companies have tended to operate as focused mineral extractors, supplying their product to the metals commodity markets or under long-term contracts to a small number of customers. Under this model, the key to success has been the ability to secure low-cost resources and manage efficient, stable operations in each location.

Each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. Industry-standard estimating methods are used for equipment selection, personnel allocation, and cost estimation.

The Cost Models section is a comprehensive section including models for surface mines, underground mines, placer mines, milling and crushing, concentrating, carbon-in-pulp, heap leaching and portable crushing operations.

to estimate costs for future coal mining projects within a coal-mining country. The model runs from an MS Excel® spreadsheet and capital costs are estimated to an order-of-magnitude level, which is appropriate for use at a concept study level. With all the cost models, data is normalized to ensure consistency.

Once coal is mined, it must be transported to consumers. Transportation costs add to the delivered price of coal. In some cases, such as in long-distance shipments of Wyoming coal to power plants in the East, transportation costs are more than the price of coal at the mine.
