With K-MINE, you can automatically design open pits, dumps, and other elements of mining operations online. A road ramp is constructed to the entire depth of an open pit. By changing the initial point of a road in an open pit, you can avoid the need to construct it manually multiple times. As a result, connecting two or more transport ...

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.
