The mine is accessed by a tunnel and the ore is hauled to the surface through a railroad system. The hauled ore is sent to the crushing plants on surface from where it is conveyed to a concentrator and the produced copper concentrate is sent to nearby smelter. El Teniente is one of the first mines in the world to deploy semiautomated load haul dumpers (LHDs) for ore extraction in 2004 ...
"The surge tunnel is equipped with three Syntron MF400 54inch by 84inch electromechanical pan feeders mounted to the ceiling. Each feeder is capable of supplying up to 1000 tonsper hour of throughput down onto a new 48inch by 475foot collector belt. This collector conveyor is offset 36 inches from the centre line of tunnel to maximize maintenance access on the far side.

Ruffner No. 2 mine (originally part of the Irondale Mines or Upper Sloss Mines) was an ore mine operating from about 1886 to 1953 on the southeastern slopes of Ruffner Mountain to supply the SlossSheffield Steel and Iron Company with red iron ore. The mine's ore crusher and other ruins remain as points of interest in the Ruffner Mountain Nature Preserve.
In order to mine iron ore underground, we have to build transport routes in the rock, tunnels known as drifts. Development consequently entails making preparations for mining. A development drift is blasted directly through the ore body and, if necessary, the walls and roof are reinforced with bolts, mesh and sprayed concrete. Production drilling. When the development drifts are ready ...

· Underground conveyor belts in coal handling appliions mandatorily have fire resistant grade cover rubbers. Even in certain noncoal underground conveyors, where the ore deposits coexist with intense 'carbonaceous horizon' (in geological parlance), belts with fire resistant cover grade is used.
