Development of an energy analysis for strip coal mining. Part III: Procedure for evaluating the energy intensity of technological processes

Conclusion Traditional evaluation of the energy intensity of the technological processes of strip coal mining with respect to direct energy consumption is not exhaustive, since energy expenditures for the production of required resources in accompanying branches of industry, and the mining of fuel for the production of energy, the amount of which should be significantly higher than the sum directly expended for the mining and creation of the facilities for its execution are not considered. The proposed method for evaluation of the total energy intensity of technological processes is based on the link between basic energy outlays and production of the required resources. Evaluation not only of their direct energy intensity, but also with respect to individual forms of consumable resources is therefore critical to the analysis; this is the basis for a search for means of lowering the energy intensity of production on the whole and the development of resource-saving technologies.

Substantiation of the sequence for opencast mining of a series of flat and inclined strata using the mined-out space for internal dumps

The possibilities of using the mined-out space of opencasts for placing the overburden in internal dumps are studied.

A maximum upside / minimum downside approach to the traditional optimization of open pit mine design

The management of cash flows and risk during production is a critical part of a surface mining venture as well as an integral part of a strategy in developing new and existing operating mines. Orebody uncertainty is a critical factor in strategic mine planning, the optimization of mine designs and long-term sequencing. Traditional optimization approaches do not account for in situ grade variability or deal with geological risk.
