Choosing the right type of backfill has become very project specific; constraints such as schedule, cash flow, source materials and regional skills all impact the choice of backfill type and source. The successful implementation of a backfill system is dependent on a number of factors; a fundamental understanding of the material properties and geomechanics, balanced process engineering and hydraulic design, safe placement strategies and cost-effective operational management planning are all important in order for backfill to do its job - support the mining cycle at the lowest cost possible!
Participants will gain an appreciation of the requirements for designing and operating a safe, costeffective, and reliable backfill system. The course objectives are to: Introduce the fundamental concepts of geo-mechanics and material properties; Examine the various elements that go into engineering a backfill system, including testing, plant and process design, reticulation and barricades; Relate to operational aspects of a backfill system including quality assurance, cost reduction, operational management plans, risk control and new technology.
Content & Program
The intensive 4-day course consists of 3 days of technical lectures, case studies and laboratory demonstration sessions, followed by an optional site visit (surface and underground) to Goldcorp’s Éléonore Mine in Northern Quebec to examine its paste backfill system. The course will be delivered in English.
