Manekar, Ganesh G.
This system can be adapted to many different ore body shapes and ground conditions. Together with room-and-pillar mining, it is the most flexible of underground methods. In cut-and-fill mining, the ore is removed in a series of horizontal drifting slices. When each slice….

Rock Mechanics pp Cite as. An analysis was presented in Chapter 13 of the yield potential of an orebody when mined with a naturally supported method. It showed that under certain circumstances, the maximum extraction possible from the deposit may be unacceptably low. This conclusion applies particularly when the compressive strength of the rock mass is low relative to the local in-situ state of stress. The discussion in Section

Show all documents Experimental and Analytical Studies to Achieve an Optimised Cemented Backfill Mix to be Used in a Cut-Fill Mining Method A schematic of the multi-slice cut -and- fill mining method is depicted in Figure 5, with respect to this method; ore to be mined from stope A in a series of horizontal slices height of one meter, after each slice is removed backfill is placed into the stope using concrete, creating sufficient working platform to extract ore for the next slice. After six slices have been mined out, extraction of stope B can be started. A concrete pillar will be formed by filling the mined portioned would act as a retaining wall stabilising for stope B.

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals , usually those containing metals  such as ore containing gold , silver , iron , copper , zinc , nickel , tin and lead , but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt , coal , or oil sands. Accessing underground ore can be achieved via a decline ramp , inclined vertical shaft or adit.

Но Стратмор смотрел на молодого сотрудника лаборатории систем безопасности. Коммандер спускался по лестнице, ни на мгновение не сводя с него глаз. Он быстро подошел к ним и остановился в нескольких сантиметрах от дрожащего Чатрукьяна.
