MODELING OF COAL DEPOSITS IN THE POLAR ZONES OF YAKUTIA

Abstract

There is a problem of increasing the energy security of Arctic regions in the Republic of Sakha (Yakutia) related to a number of specific features of these territories. Involving into exploration the local resources of coal on the basis of comprehensive analysis and evaluation with due regard for specificity of each particular region can become one of the methods of smoothing the problems of stable and reliable supply of the region with fuel. Currently information-analytical system is being developed in the Institute of Mining of the North, the Siberian Branch of RAS, which includes databases of coal deposits, their digital models, as well as information on producers and consumers in the region with taking into account the existing and future geo-technologies, recycling technologies of solid fuel, transport and logistics schemes. There is a state registered database "Coal deposits of polar zones of Yakutia" in the basis of the system.
Works connected with computer modeling of deposits with subsequent study using the methods of geo-statistics of nature and patterns of spatial coal reserves distribution and its quality in the bowels and simulation conditions and order of individual mining blocks are being carried out for deposits of the region that are alleged to priority development and were pre-selected on the results of peer review. All this ultimately contributes to the investigation of geo-technical processes for optimization their parameters and construction of coal quality control systems.
The article presents the results of the simulation of a number of Arctic fields. The quality of the coals of the two fields was compared in terms of the feasibility of mutual mpared. In this case deep analysis is impossible without using mining and geological information systems, such as, for example, MINEFRAME and Micromine for modeling purposes.
