Imz block caving
WitrynaConducting such a test in a block caving mine is still considered not feasible, due to the fact that markers movement will be influenced by caving process, and the cost ... (IMZ) at height of draw less than the ore column height. The results also conclude that more physical model experiments, other than 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 …

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. 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. …

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. 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 …
Witrynathis case, block caving gets the attention of mining engineers. At present, block caving has already got application in many mines across the world including America, Chile, South Africa, the Philippines, Canada, Australia, China, etc [3]. Among the 50 mines with block caving, Teniente mine in Chile has the largest production output of 140000t/d.
