Orica’s FRAGTrack™ wins international Good Design Award

Orica’s innovative fragmentation measurement technology FRAGTrack™ has been awarded a Good Design accolade in the engineering category, for outstanding design and innovation. 

Dating back to 1958, the annual Good Design Awards recognise and celebrate products or services that have shown excellence in design innovation and impact. 

FRAGTrack™, Orica’s automated fragmentation measurement device, accurately and reliably measures rock size and fragmentation following the blasting stage in mining and quarrying. For these sites, optimal fragmentation can greatly reduce energy consumption, improve equipment productivity, and increase production rates – and removes the need for manual sampling to keep team members safe.

Nexa Resources improves Safety and Ore Recovery with first WebGen blast

By applying the unique features of Orica’s fully wireless initiation system, WebGen™, Nexa Vazante (Nexa Resources) significantly reduced ore dilution from 27% to 20%, resulting in a net benefit of US$1.59 million.

The single blast event achieved a smaller hydraulic radius by keeping the pillar during the stope extraction which in turn resulted in a reduced cycle time to 20 days, down 70% from an expected 90 days by maintaining two mucking access points to the main stope, only possible due to the wireless capability of WebGen™. The unique blasting approach dramatically improved safety by pre-loading the pillar with WebGen™, minimising the exposure of personnel and removing the need to re-enter the area.
