Design and Operational Issues for Increasing Sublevel Cave ...

Kvapil(1965). Gravity flow of blasted ore and caved waste in sublevel caving is a process more complicated than that which is used in bin flow. The geometry, dimensions, and even operational constraints of sublevel caving cannot be selected at random but must be planned while respecting the characteristics of gravity flow of coarse materials.

Underground Mining Methods and Equipment

Caving methods are defined as those associated w ith induced, controlled, massive caving of the ore body, the overlying rock, or both. Th e exploitation workings in caving methods are designed to collapse, with intentional caving of the ore and/or host rock. The three major caving methods are: • Longwall mining • Sublevel caving

Design of a new layout for sublevel caving at depth

Transverse sublevel caving layout is the normal layout at LKAB, but when the orebody is narrow, longitudinal sublevel layout is used. In this paper, only transverse sublevel caving is discussed, i.e. the production drifts are driven across the orebody from the footwall to the hanging wall. The dimensions of

14 December 2018 Sublevel Caving success at Syama

Sublevel caving comprises a series of repetitive activities and is ideally suited to automation. Syama is well suited to the sublevel caving mining method because of its scale, width, orientation, and uniformity of grade. Unlike other bottom-up caving methods (block cave, panel cave) sublevel cave mining is a
