Innovative technology delivering continuous production can transform open-cast mining, says Chris Pearson
constantly struggling to pass-match trucks and shovels. T e answer lies in innovative technology that can deliver the benefi ts of continuous mining using existing truck fl eets, without the need to install capital- intensive conventional conveyers.
W
hilst the mining industry focuses increasingly on sustainability and safety, open-pit mines are
Shovels represent considerable CAPEX
and OPEX costs, yet the effi ciency of a shovel seldomly sustains 60% of its capacity. Industry expert MMD recognised that it could design a machine that harnessed the capability of the shovel and vastly improved the speed of loading trucks. T e machine in question is a fully mobile surge loader (FMSL) – purpose- designed to bring continuous production to open-pit mines. T is innovative
solution draws upon MMD’s experience in Colombia some 16 years ago as well as a more recent in-pit sizing & conveying (IPSC) installation in China. T ere is a lot of room for improvement in accuracy and effi ciency here. Trucks rarely achieve 90% of their fi ll factor and most large electric rope shovels rarely load above 6,000 tons per hour (tph), when they should be loading at 10,000 because they are waiting on trucks.
