Two recent examples of mining under backfill at large mines in Ontario are presented. At the Williams Mine in the Hemlo camp, extraction under the cemented rockfill sills of two major mining blocks at 900 m and 1100 m depths has started. At the Garson Mine in the Sudbury basin, an instrumented test opening has been mined under a paste backfilled blast hole stope. An outline of the mining approaches adopted, analytical studies and monitoring results are presented, together with conclusions regarding the performance of the two different backfilling systems.
