Miners can unearth surface material through strip mining, quarrying, and open-pit mining. In addition, those different mining methods bring various mining equipment into the enclosed environment of underground work, such as massive earth-moving trucks and rotary drill rigs. Surface and blast mining often go hand-in-hand since …Web
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
This work deals with the short-term planning problem of a work shift for open-pit mines. The problem involves ore and waste fronts, shovels, heterogeneous truck fleets, and discharge points.
