Karowe Mine, located approximately 16 kilometers (km) southwest of the town of Letlhakane, is a diamond mine where the second largest diamond ever found on record, with a weight of 1,111 carats, was discovered. This project involved simulating mine dewatering and excavation to evaluate future dewatering requirements, as well as providing guidance for future monitoring borehole and piezometer designs.
The 56th US Rock Mechanics / Geomechanics Symposium covers all aspects of rock mechanics, geomechanics, and rock engineering.
Mr. DeGagné is a geomechanics 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.
