METHOD OF VARIABLE MODELING OF GEOLOGICAL AND ECONOMIC ASSESSMENT OF SOLID MINERAL OBJECTS
In the Russian Federation, issues of mining and consumption of mineral resources have a direct impact on the socio-economic condition of the state. Moreover, the scale of production and consumption of raw materials is constantly growing, while the reserves of deposits are not unlimited and non-renewable, which can lead to a sharp deterioration in the quantitative and qualitative indicators of the state of the mineral resource base. Currently, researchers are increasingly focused on the need for a high-quality geological and economic assessment of objects. The results of the assessment, in fact, depend not only on the decision on the prospects of a particular subsurface object, but also on the overall effect of exploration on the subsurface area for budgets of various levels, the income of employees of a mining enterprise that produces on this site, and the environmental load within the radius of influence of the mineral resource object. Due to the existence of different approaches to the geological and economic assessment of objects, it is necessary to thoroughly study them, evaluate their reliability and efficiency at specific objects. The purpose of this article is to develop a methodology for variable modeling of the geological and economic assessment of solid mineral objects using software tools.
Keywords: geological and economic assessment, net discounted profit, modeling of field development, testing of reserves.
Highlights:
♦ the essence of variable modeling of geological and economic assessment in this case is that the development of a feasibility study of exploration and operational conditions is recommended to be carried out in at least two variants, conventionally called basic and commercial;
♦ in terms of the basic option, the potential balance field reserves are estimated, while the commercial assessment determines the part of them that can be worked out in the current economic conditions with an acceptable effect for the subsurface user;
♦ as a result of the research, it was also possible to perform a geological and economic assessment of promising mineral resources in the Bryansk region.
