Study of multiple draw-zone interaction in block caving

Witryna31 sie 2007 · Abstract Block caving methods rely on gravity to break and transport large amounts of ore and waste. Despite the importance of gravity flow, there is debate within the literature about the influence that the height of draw, particle size and particle size distribution has on the geometry of extraction and movement zones.

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. … WitrynaDOI: 10.1016/J.IJRMMS.2007.01.001 Corpus ID: 53053016; A study of isolated draw zones in block caving mines by means of a large 3D physical model @article{Castro2007ASO, title={A study of isolated draw zones in block caving mines by means of a large 3D physical model}, author={Ra{\'u}l L.

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, … WitrynaThe success of that mine led to a significant expansion into block caving operations, first at Ridgeway Deeps, and then to the now established Cadia East operations. What makes Cadia unique is the high-stress, hard rock mining conditions combined with the ability to maximise investor returns through the use of very high lift heights at depths ...
