sublevel caving mining method

Sublevel caving is a systematic method and uses regular layouts and working procedures. Development, production drilling and loading are carried out on separate levels, all independent of each other. Also, a number of faces are always available for production.

Oct 25, 2017 The loss and dilution of ore by sublevel caving mining method is influenced by gravity flow principles of caved granular materials (rocks). Gravity flow of broken rock (muck) in dipping narrow veins is complex. By combined use of dimensional analysis and similitude studies in physical modelling coupled with numerical simulation, this paper reports results of a study of gravity flow of muck in ...

Longwall mining. Longwall mining is a type of caving, applied to a horizontal tabular deposit such as coal. While block and sublevel caving are essentially vertically advancing metal mining methods, longwall mining is applied to relatively thin and flat-lying deposits – most often coal, but occasionally an industrial mineral such as trona.

Apr 05, 2017 Sublevel caving lacks the flexibility of supported-stope methods but is more flexible than block caving. The sublevel development serves to explore the ore body at each caving horizon before mining begins, and irregular boundaries can be followed more easily than with block caving and with less dilution from the walls.

Jul 14, 2014 This method is unlike sublevel caving, in that both the ore and the rock are normally involved in the caving. As in sublevel caving, The caving proceeds in a columnar fashion to the surface. The result is massive subsidence, accompanied by the exceptionally high production rate and great areal extent characteristic of block caving. 3.
