10-01-2017· From these ports the mining of the ore begins on the bottom of the ninth level. The first cut of this ore is mined about 8 to 10 feet high and the spaces from which the ore has been removed are filled with rock. This rock-filling follows the mining and affords absolute safety and inflexible support to the walls of the mine.
Metal ore mining in Europe Mineral Processing. Since the iron ore is extracted in underground mines (Fig. 2), mining costs are hardly competitive compared to the open pit mines of, for example, Australia or Brazil. As a consequence, the low iron ore prices have been very problematic for mining companies.

Opencast to underground iron ore mining method At the end of the openpit mining process in large metal mines, the mining model must change from openpit mining to underground mining, but the mutual interference between the two mining models leads to poor production safety conditions and difficulties in production convergence during the transition period To solve these technical problems of …
In order to mine iron ore underground, we have to build transport routes in the rock, i.e. 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.
