WitrynaAbstract: This paper reviews previous work on the Isolated Extraction Zone (IEZ) in Block Caving, and in particular, the parameters and mechanisms controlling the shape of the IEZ. Previous work is divided into four separate approaches namely: scaled physical modelling; numerical modelling; full scale marker trials; and empirical … WitrynaOver the last 10 years, the trend toward the mining of deeper, higher tonnage deposits, and lower grade orebodies have made caving mining methods (Block and Sublevel) increasingly attractive to the global mining industry. This is due to their low mining cost. During this period the scale of these caving operations has increased significantly. …

Draw control based on PCSLC model The PCSLC model is a mine planning module developed in Dassault Systemes Geovia's GEMS … WitrynaThe use of block caving to mine deep, massive, low-grade ore bodies is gaining increasing attention from the mining industry given its merits in terms of safety, tonnage produced and costs that can match those of open-pit operations. However, the undercutting and bulk extraction of ore through caving (Kendorski, 1978; Brown, …
