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.
