Since April, Codelco’s Salvador Division underground mine has presented a positive trend, which is reflected in the 17% increase in production, which in June and July exceeds the budgeted in the programme.
The Minas General Superintendent, Marco Nehgme, explained that there are three fundamental factors that influenced this achievement:
- The change from 8 hour to 12 hour shifts in a 14 x 14 day cycle, due to the pandemic.
- The improvement of the availability of the load, haul and dump fleet.
- The responsibility of the personnel in the fulfilment of the measures against the coronavirus.
"The sanitary crisis did not have a negative impact on our underground operation. People complied carefully and responsibly with the preventions, which generated a more effective operational continuity. The reduction from three to two shifts, due to the exceptional workday, avoided hourly waste in the changes, so the use of the equipment and the availability of the fleet increased from 18 to 20 hours a day."
Likewise, the staff has been meticulous in complying with the COVID-19 measures, both at the job site and during breaks. To date, no worker has been infected during their work cycle, an important contribution to operational continuity. The results achieved explain the decrease in direct costs of 20%, compared to what was budgeted.
