Consulting Services

Our core Service

Our core services range from backfill geomechanics (mix designs and mix optimization, strength assessments, numerical modeling) to plant designs, construction and commissioning. Much of our backfill work is aimed at scoping studies and feasibility studies for backfill plants and paste plants including conceptual level to basic engineering level designs, equipment sizing and selection, capital and operating costs, and project scheduling. We maintain a close liaison with vendors in the market and a library of vendor costs.

MineFill Services’ expertise in backfill reticulation systems includes pump selection and motor sizing, pipeline analysis, pipe selection and sizing, instrumentation and monitoring, and barricade designs.
