Backfill Design

Itasca offers services in backfill characterization, specification, design of mixing and delivery systems, stability analysis (exposure stability, reinforcement and closure resistance), dynamic modeling to examine stability and liquefaction potential under rockburst and rockfall conditions, and instrumentation and testing of placed backfill. These services cover a wide range of backfill products (paste fills, hydraulic fill, cemented aggregate fill, and rockfill) and have been applied to mining operations throughout the world. Itasca also has developed specialized methods for simulation of the deformation and yielding of backfill, bulkheads, and backfill mats.
