Unidad Minera Huachocolpa

  • Client: Compañía Minera Kolpa S.A.
  • Year: 2019
  • Problem: High rotation of personnel generates values that fall below standards for pull tests conducted on helicoidal bolts.
  • Solution: On-going training, correction of the process to install support and periodic campaigns for start-up tests.

Unidad Minera Morococha

  • Client: Sociedad Minera Austria Duvaz
  • Year: 2021
  • Problem: Elevate use of anchor bolts due to friction when applying set split bolts in areas where rock quality is in the IV A range.
  • Solution: Replaced anchor bolts with hydraulic expansion bolts (Swellex) and generated a 33% reduction in the total sustaining cost.

Unidad Minera San Cristóbal

  • Client: Minera Bateas S.A.C.
  • Year: 2019
  • Problem: Electrowelded mesh openings of 4”x4” elevated the sustaining cost; the format of these openings meant that rocks were able to pass through, which generated incidents.
  • Solution: Replaced this mesh for Meshpro® caliber N°10 with openings of 3”x3, which reduced the sustaining cost by 10%.
