Why is block caving so important today?12 Oct 2020 13:43

As low-grade orebodies can only be mined profitably if they are big and mined with a low-cost mining system at high tonnages, Suorineni considers block caving’s efficiency as a major driver of interest.
Big mining companies are already capitalising on the potential of the method, with Rio Tinto extracting ore south of Ulaanbaatar, Mongolia; Resolution Copper mining copper in Arizona; and Newcrest exploring copper and gold at its Red Chris mine in New Wales, British Columbia.
Suorineni believes that with the increasing popularity of the method and emerging technologies such as artificial intelligence, virtual/augmented reality, robotics and automation, and big data, most of the bottlenecks involved in block caving will soon be eliminated.
He also suggests that space exploration technologies such as those used by Curiosity on Mars could be adapted to improve the efficiency of the system.
“Coupling emerging technologies with the block caving mining system, increasing frequency of low-grade orebody discoveries and its continuing popularity makes this the mining system of the future,” Suorineni concludes.
As block caving is the only underground method that can offer comparable open-pit production rates and operating costs, the technique is set for a strong future on the mining stage.
