ECONOMIC EFFICIENCY ASSESSMENT OF GEOLOGICAL EXPLORATION WORKS IN THE PROCESS OF GEOLOGICAL EXPLORATION OF SUBSURFACE RESOURCES
The relevance of the economic assessment of the effectiveness of geological exploration works in the process of geological exploration of the subsurface resources consists not only in the need to ensure the stages of the geological exploration process, but also in the need to increase the reliability of the economic assessment of the effectiveness of geological exploration works in the process of geological exploration of the subsurface resources. As practice shows, it is the geological study of the subsurface that is the most expensive and high-risk process, the effectiveness of which largely depends on the ability to estimate the costs of increasing reserves with the greatest accuracy, especially in terms of industrial categories. Therefore, it is necessary to develop a methodology for evaluating the effectiveness of geological exploration, the use of which would allow estimating costs and results at the planning stage. The quality of geological exploration works at the object is determined by the increment of the initial geological and economic information. The greatest risks when performing geological exploration works arise when interacting between the state customer of geological exploration works at the early stages of geological exploration and geological organizations performing works under state contracts. As a result, a method of economic evaluation of the efficiency of geological exploration works in the process of geological exploration of the subsurface was proposed, which was tested on solid minerals, using the example of the Central Federal District.
Keywords: economic assessment, project management, geological study of subsurface resources, economic efficiency of subsurface use.
Highlights:
♦ the industry efficiency of geological exploration is estimated by the ratio of the costs of conducting geological exploration works with the results obtained, which are characterized by the performance of the project task for geological study, forecasting, prospecting, preparation of proven reserves for industrial development;
♦ to calculate the efficiency of geological exploration works, the following parameters should be used: the project task, represented by the number of explored reserves or forecast resources and their ratio by categories; the actual performance of the geological task; the estimated cost of works on the geological task; the actual costs of performing geological exploration, as well as specific indicators in terms of planned and actual costs of conducting geological exploration works;
♦ when designing geological exploration works by categories, it is recommended to apply correction coefficients to increase the cost of geological exploration works, depending on the degree of reliability of the obtained geological results.
