Surface mining operations: coincident unit cost and emissions

摘要: Traditionally, surface mining has been organised based on a minimum unit cost criterion. However, there is an increasing awareness for the need to reduce carbon emissions due their negative environmental impacts. This paper explores relationship between optimal operation and operation. It examines influence of range parameters including truck size, payload, fuel use travel load times. demonstrated theoretically that optima with respect coincide, this coincidence invariant changing parameters. To support theoretical result, data from extensive field study are used, time production measurements, collected burn its conversion emissions. The paper’s findings will be interest those involved in designing managing mining, similar operations such as quarrying earthmoving.
