Our team are experienced in the investigation of backfill materials, and the design and operation of backfill plants within the mining and minerals processing industries. Designing, constructing and operating a backfill system that reliably meets performance requirements is critical to the safety and financial success of an underground operation. pitt&sherry apply their backfill materials, plant design and operating system knowledge in the following areas: Scoping, pre-feasibility, feasibility, design and costing studies. Backfill system optimisation Material characterisation and mix design optimisation Operational systems design including safety procedure, barricade design and fill sequencing Operational systems audits, trouble shooting and on-site backfill technical support Geotechnical backfill performance modelling including local and regional stability analysis, and numerical modelling.
