Mine Backfill Systems

 Mine backfill has unique challenges. Black Rock Engineering is familiar with these challenges, having completed many backfill-related projects over the years. Whether it’s an entirely new backfill plant or a modification to an existing one, Black Rock can provide the study and/or detail design.

Design of Backfill Plants

We can design the complete plant, including:

  • Thickeners
  • Cyclones
  • Storage tanks
  • Cement/fly ash silos
  • Flocculant addition systems
  • Mixers for pastefill, hydraulic fill, cemented rockfill
  • Permanent or portable backfill plant solutions
  • Hydraulic, paste, cemented rockfill
  • Backfill instrumentation and controls
Backfill Distribution Systems

Black Rock designs the distribution systems, including:

  • Piping, pumping and distribution—surface and underground
  • Deep mine slick lines and boreholes
  • Flushing requirements
  • Instrumentation and controls
  • Shotcrete/Cement boot and diverter valve
System Analysis

We can provide:

  • Capital and operating cost estimates
  • Stress analysis for all components listed above (FEA).
  • Wear of pipelines
  • Energy cost
  • Vibration and noise
  • Safety
