Russia is the largest country in the world and occupies one of the leading places on the planet in terms of natural resources, but the bulk of deposits were explored to some extent more than a quarter of a century ago, back in the Soviet era. Due to the changes in the sources of financing for the reproduction of mineral resources and geological exploration of the subsurface, qualitative and quantitative indicators are reduced by an order of magnitude, which leads to greater risks in the development of mineral deposits. Even despite the large number of scientific papers, the economic situation forces us to search for more modern and multi-parametric methods for evaluating the efficiency of mining. The article considers the main economic methods for evaluating the efficiency of mining, determines their essence and application features. On the basis of conducted analysis, disadvantages and advantages of using the studied methods were identified, and the author's interpretation of the economic assessment of efficiency of mining resources was given.

In such economy-economic defined conditions of the valorization of mineral resources of Serbia, especially important role has the connected genetic and geological–economic modelling of the deposits of the mineral row materials.

Improvement Of Legislation

The improvement in valorisation of industrial minerals and rocks in Serbia is related to improvement of legislation, and to adoption of best possible techniques for geological exploration and estimation of resources/reserves. Therefore, we analyzed the actual practice in the field of geological exploration which has not changed significantly in the last 30 years, as well as legislation related to the mining industry and access to land. The improvement of legislation mostly depends on the state authorities. Contrary to that, the enhancement of geological exploration methodology should be the issue of experts working in that area of the mining industry but is also very much related to the existing legislation. Serbia still has very strictly prescribed procedures, which are generally good; however, it is an overly complicated and restrictive system for performing geological exploration and evaluation of mineral deposits. The most important improvements in legislation in the last twenty years are presented and discussed, as well as problems that still need to be solved and solutions found to fully understand the potential of industrial minerals and rocks in Serbia.

In coalfield geological exploration, in the face of complexity and levity of geological bodies, the reservoir geological modeling technique a new and high technique grown up in recent years, plays an important role on exploration and development of CBM. Reservoir modeling would be finished through 3 stages: reservoir structure modeling, precipitation facies modeling, reservoir properties modeling. A 3D geological model may carry out the meticulous description of coal reservoir , and quantitatively characterize the inhomogeneities of reservoir. In addition, geological modeling is of great importance to engineering design and construction as well as information management, analysis and decision making.

Background. The geodynamic approach is effectively used in regional forecasting and prospecting works. However, its application for local forecasting and prospecting for solid minerals is limited and sometimes impossible. One of the key problems of local forecasting and prospecting for minerals (solid, liquid, gaseous) is the presence of non-standard (flickering) geophysical anomalies, which complicates the interpretation of the results of geophysical surveys performed at different times at different stages of geological exploration. The article is devoted to clarifying the possibility of using geodynamic research in local forecasting and prospecting for solid minerals on the basis of attracting the latest scientific knowledge from the field of studying the spatio-temporal patterns of the development of modern geodynamic processes and their influence on the Earth’s geophysical fields. Aim. To increase the reliability of interpreting the results of geophysical surveys performed for local forecasting and prospecting for solid minerals.Materials and methods. The research was carried out on the basis of a comprehensive analysis of literature data, fund materials and the results of many years of the author’s own research in the fields of modern geodynamics and prospecting and exploration geodynamics. The initial data were based on the monitoring data of various Earth’s geophysical fields (deformation, seismic, and surface magnetic).Results. A geodynamic reason for the appearance of flickering anomalies in the Earth’s geophysical fields (in particular, magnetic) has been established, and a mechanism for their formation under the influence of modern geodynamic processes has been proposed. The possibility of using the geodynamic approach in the prospecting for solid minerals has been expanded, and ways to increasing the efficiency of local searches have been proposed.Conclusions. The research demonstrates the possibility of using geodynamic studies in local prospecting for solid minerals, which helps to increase the reliability of the results of interpretation of geophysical survey data, and, as a result, to reduce the overall financial and time costs involved with searching for mineral deposits.
