Mr. DeGagné is a mining engineer with experience in rock mechanics, including slurry and paste backfill, and sublevel caving. He has developed an alternative binder using recycled glass for use in backfill and has developed numerical models using PFC3D and the parallel-processing option to simulate the flow of ore and waste draw in a sublevel cave mine. He has also worked with FLAC3D, FLAC, UDEC, and 3DEC numerical modeling.
