Mineral and raw materials complex (MRC), which unites the industries engaged in prospecting, exploration, mining, processing of minerals and utilization of secondary resources, largely determines the successful development of the economy and scientific and technological progress of our country. About 40% of capital investments are spent on the development of the mineral resource base, and more than 18% of industrial labor resources are employed in the mining industries.
The result of prospecting and evaluation work should be the selection of promising deposits for preliminary exploration and rejection of non-industrial ore occurrences ...
Scientific management of mineral resources is among the important national economic problems of rational and integrated use of subsoil, set by the XXV Congress of the CPSU ...
For a systematic and rational study of the mineral resource base of the country, geological exploration is carried out in successive stages. In this sequence, an important place belongs to prospecting and evaluation works, in the process of which the fields are sorted out and the objects for preliminary exploration are determined ...
Expansion of geological exploration and accelerated development of the mining industry are the most important tasks of the national economy in the 10th Five-Year Plan ...
In recent years, an exceptional amount of attention is paid to the problems of economic justification of the efficiency of exploration work. Nevertheless, there is still no generally accepted methodology for determining the economic efficiency of exploration work.
The economic evaluation of mineral deposits should be based on the cost assessment of proven reserves of mineral raw materials to justify the acceptable level of socially necessary costs for its exploration, production and processing. Such an assessment is also necessary to ensure the most complete and rational use of subsoil. ...
Within the ore field of the studied gold deposit sandy-shale deposits of the Lower Permian with thickness up to 2000 m are spread. The deposit is located in the near-axial part of a brachyanticlinal fold of meridional strike. The meridional and north-eastern and south-western breakers of the chipping type are widely developed.
Economic efficiency of exploration of any deposit depends on the correct choice of technical means and rational placement of the necessary number of exploration intersections. The latter is determined, as a rule, by the degree of variability of the main parameters of the field ...
The conditions of prospecting and exploration of deposits, as rightly noted by V. I. Smirnov, are becoming more and more complicated every year, as most of the work is carried out in hard-to-reach areas and in an increasingly complex geological environment. In modern conditions, when the economic factor in the exploration of mineral deposits is given decisive importance, the problem of identifying such deposits and ore bodies, which contain the main industrial reserves of this type of mineral raw materials comes first...
