Witryna1 paź 2008 · Block and panel caving have evolved from that time from being applied to low competent rock and low block heights to be now used for a wide range of rock mass competences and block geometries. It is now quite common to exploit coarse fragmented caved rock. Witryna1 paź 2008 · The limit of the isolated movement zone (IMZ) interaction has been determined by observations of the flow of sand and finely fragmented caved rock. …

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.

The results also conclude that more physical model experiments, other than Witryna1 wrz 2007 · Block caving refers to mass mining methods in which the ore body caves naturally after undercutting and the caved ore is recovered through drawpoints. These … Witryna1 cze 2009 · The block caving technique is based on two process; the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of compact material located in the upper layers because of the stress propagation generated by the extraction process. linear regression on csv file

Witryna1 paź 2008 · The limit of the isolated movement zone (IMZ) interaction has been determined by observations of the flow of sand and finely fragmented caved rock. … linear regression on excel graphWitrynaThe 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 ... linear regression on desmos

"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. … " - Imz block caving

WitrynaThe work in this thesis is directed towards the development of a model for gravity flow prediction that can assist in the design of a drawpoint layout and draw schedule that maximizes recovery of ore from block and panel caving mines. Experience suggests that maximum recovery and minimum dilution are achieved most easily if one is able … WitrynaThe three main principles guiding the growth of IMZ are porosity, collapse, and erosion (Pierce, 2010). Draw control based on PCSLC model The PCSLC model is a mine planning module developed in Dassault Systemes Geovia's GEMS …

WitrynaThe first, called the isolated extraction zone (IEZ) is defined as the region of material that has been drawn from the model and the second called the isolated movement zone (IMZ) is defined as the limit of movement induced by the extraction. WitrynaCurrent production level design guidelines in block caving mines are based on the concept of interaction of movement zones and the spacing of draw-points at which mass flow is achieved. The limit o ...
