Slope Design Criteria for Large Open Pits - Case Study

The Cadia Hill Open Pit has been in operation since 1997. The current pit measures 1.5 km in diameter and 340 to 500 m deep. The open pit mining rates have been between 40 to 80 mtpa, with ore production at 17 mtpa at 0.77 g/t gold and 0.18% copper. The annual production is approximately 300,000 oz gold and 23,000 t of copper.

Selection of practical bench height in open pit mining ...

2015-9-9  In open pit mining, factors that can affect the degree of dilution can be regarded as deposit-related or mine-related. The bench height is a mine-related parameter that can be studied using a simple geometrical model of the deposit. By changing this parameter individually, while the deposit-related parameters (such as ore

2013-9-5  Abstract. One of the most important design factors in open-pit mining is determination of the optimal pit. Pits may be redesigned many times during the life of a mine in response to changes in design parameters as more information is obtained and to changes in the values of technical and economic parameters.

Methodology for a dump design optimization in large

2021-2-19  In large-scale open pit mines, the mining process is rather complex and often involves different run-of-mine (ROM) ore and waste material treatment downstream. Appropriate areas to place these large amounts of material are limited and their selection and design must serve the environmental factors and economic goals of the long-term mine plans.
