The effective operating time (EOT) of the equipment in an open pit mine determines the capacity of the mine. Clearly, EOT is only a part of the total calendar time, which also includes various down times or non-productive times, caused by different factors. Therefore, it is important to analyze the components of calendar time. A logical prerequisite for such …
Over the past century, open pit mines have steadily increased their production rate. Larger equipment and new technologies make it possible to mine larger batches of materials in a shorter time. Low commodity prices have forced companies to decrease their unit cost, by using new technologies and improving productivity.

PwC's analysis reveals that deployment of the autonomous mining equipment in open-pit mines has grown significantly in the last two decades in both developed and emerging markets. Additionally, the adoption of such technology cuts across the mining of commodities such as iron ore, gold, copper and coal. In 2007, only 18
Introduction Equipment selection is one of the most important aspects of open pit design. Mining costs are mainly affected by the number and capacity of equipment. Equipment selection for open-pit mines is definitely a major decision which will impact greatly the economic viability of an operation (Aghajani et al., 2007).
