Witryna1 mar 2024 · The following assumptions and simplifications were made to study the stress behaviour in block caving through physical modelling: (1) It is assumed that the rock mass has caved to surface, forces in the system are due to the material's weight, and in-situ stresses are not present. (2) The granular flow occurs in a 3D environment.

STUDY OF MULTIPLE DRAW-ZONE INTERACTION IN BLOCK CAVING …

WitrynaThe limit of the isolated movement zone (IMZ) interaction has been determined by observations of the flow of sand and finely fragmented caved rock. This paper presents a study of the mechanisms and limit of IMZ interaction in coarse fragmented caved rock using a large 3D physical model. 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.

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.

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.
