“…For the development of rock interbeds and coal seams, design organizations have adopted the following options for axcavating and loading equipment for coal-bearing zones development [8][9]: -rope shovels for excavation of interbeds and coal seams; -rope shovels and hydraulic shovels for excavation of interbeds and coal seams; -rope shovels for interbeds excavation and hydraulic backhoes for excavation of coal seams; -hydraulic backhoes and shovels for excavating interbeds and coal seams.…”

Abstract. Open coal mining companies in Kuzbass (Western Siberia, Russia) constantly face challenges to increase the economic efficiency of mining operations, reduce coal losses and increase profitability. One of the ways to increase the efficiency of open pit mining is to improve the technology for the development of coal-bearing zones of quarry fields on complex structured inclined and steep deposits. At present, the projects for promising deposits have been completed, and a number of operating open pits conduct the development of coal-bearing zones along their entire width by horizontal layers. The excavating and loading equipment for overburden and mining operations in these zones is diverse: quarry rope shovels, hydraulic backhoes or their joint work. When they work together in the coal-bearing zone, the rope shovels extracts the interbeds, and the hydraulic backhoes extract the coal seams. However, such technical solutions are not sufficiently substantiated. The fact is that rope shovels and hydraulic backhoes have their advantages and disadvantages in operating.

The evaluation of a deposit and mining project is a continuous process rather than a single act. Changes in budget, evaluation criteria, or in the area of costs and incomes may change results valid up to now and the views on using a deposit. Geological quantities are measurable with the help of geological conclusions and engineering calculations. Raw material reserves and their quality are defined as a substance that can be recovered with profit through current technologies and prices. This definition can result in two misunderstandings: geological reserves and the quality of raw materials are understood as variables not connected with mining activities. However, the quantity and quality of remaining reserves depends on changes in our geological knowledge, changing economic conditions, as well as on the exhaustion of reserves. The quantity of reserves and value of the cut-off grade depends not only on geological factors but also upon the methods of deposit extraction, costs and prices.

“…The development of inventions, technologies, trade, business, market requirements, investments, social and political events and institutions that control world trade as well as social relations within or between states may form a world-wide need that creates a required earth resource e.g. from a raw material that either has not been used so far at all or has been used only locally [1][2].…”

Digitalization of Economic Evaluation of Mineral Deposits

The issue of mineral deposit evaluation is very topical and the aim of the present article is to fill a gap, which with far has been empty. The presented results of research are aimed to describe these issues in a comprehensive way. After the changes to the economic systems in many European countries the criteria of assessment and evaluation of mineral deposits have changed significantly, and authors of these “recomputations and calculations” use various methods. In these methods the main provisions are built upon geological and industrial values, specifications and indicators, so the economic trends are not completely considered. Therefore, in coming post-industrial era the structure of mineral resources use has been changed, and the leading methods of mineral deposits evaluation must include sufficient economic values, with a new codification.
