Rodoretto talc mine (To, Italy): studies for the optimizationof the cemented backfilling

摘要: The underground talc mine of Fontane (Prali, near Torino, North West Italy) has been exploited for decades by conventional cut and fill method using loose and, in the last 30 years, cemented backfill exploiting orebody downwards. With this exploitation approach, recovery safety mining operations have greatly improved. In new section, located Rodoretto, a detailed numerical modelling carried out to simulate various geometrical conditions properties. meantime an experimental research check possibility waste rock mix order establish procedure able reduce filling costs
