By 1949 Drummond Dolomite was a 24 –hour per day operation and they shipped out 2,275,000 tons that year. However, by 1960 the dolomite deposit at the plant site was becoming exhausted. An extensive exploration project was implemented and plans were made to open up a deposit for mining five miles east of the crushing, washing and …

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 ...
