Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.Web

The diamond-wire saw, as the name indicates, is a type of saw used in quarrying. The wire saw uses synthetic diamonds as the abrasion to cut through the stone. The saw basically consists of two parts: an engine and a steel wire laced with diamond-impregnated beads. This wire is fed through previously drilled channels.Web
