Modelling Calendar Time Structure for Open Pit Mining …
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.

How Does the Open-Cut Mining Process Work?
Open-cut mining, also known as open-pit mining, is a method of extracting valuable minerals directly from the Earth's surface. The large excavations created by this process are commonly referred to as open-pit mines. This method is widely used due to its efficiency and cost-effectiveness in accessing near-surface ore deposits. 1 ...
