Mining Cost Model The mining cost model used in PanAust's pit optimization was based on a flat $/tonne base cost for material mined and an incremental $/tonne depth cost. This captured high level average costs but ignored cost differentials between blasting ore and waste. For instance, WCL was told that different rock types were to be

Long Term Planning for Open Pit Mines Revised November 2009 1 Long Term Planning for Open Pit Mines Introduction . The profitable exploitation of a mineral deposit requires considerable evaluation and planning. First it must be determined what portion of the deposit is economical to mine (the mineable reserve) and by what mining method. Then considerable effort must be made in planning and ...
open mining methods needs a lot of capital investment, which may take several decades. Before the extraction, the pit limit, which influences the stripping ratio, damp locations, ore processing site and access routes, should be designed. So far, a large number of algorithms have been developed to optimize the pit limits. These algorithms are categorized into two groups: .
Pit optimisation is a vitally important part of the mining process and is often one of the first steps carried out by engineers in open pit mine design. A pit optimisation analysis is conducted to determine the most profitable open pit design, given a mineral resource and a set of economic and metallurgical parameters. These parameters typically consist of commodity prices, .
This study aims to propose a novel artificial intelligence model for forecasting the capital cost (CC) of open-pit mining projects with high accuracy. It is a unique combination of a deep neural network (DNN) and ant colony optimization (ACO) algorithm, abbreviated as ACO-DNN. In this model, MineAP (annual mine production), SR (stripping ratio ...
