Increased focus on efficient mine planning for SA coal mines

Fri, 09/19/2014 - 00:00
Owing to current coal prices, depleting coal reserves and the increasing need for infrastructure investment, the local coal mining industry is focusing more on efficient mining and processing using existing infrastructure without added capital investment, says mining services group Ukwazi director and principal engineer Jaco Lotheringen. “With the pressure on the coal price, the need for operations to deliver specification products at a low cost has materially increased over the past two years,” he tells Mining Weekly, noting that the uncertainty of coal prices over the medium term further increases the need for most coal companies or coal mines to decrease their unit cost of coal products to remain competitive.
