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
