Abstract:
Bulyanhulu Mine in Tanzania is an underground gold mine. Tailings are pro- duced and used in part for paste as underground backfill material. The balance of the tailings is deposited on the surface as a paste. Research is currently underway to determine the optimum method of deposition. The mechanical behaviour of the tailings was assessed by means of a field monitoring program. Various soil parameters such as gravimetric moisture content, suction pressure and, in-situ density were measured for a period of approximately three months on a freshly deposited beach. Measurements were taken at regular intervals between the dis- charge point and the toe of the beach on a daily basis. The results of the field monitoring program provided valuable information on the unsaturated soil behaviour with particular reference to the air entry value and moisture retention curve. 220 Paste 2005, Santiago, Chile Bulyanhulu Mine Paste Tailings...
