MODELLING AND DESIGN OF TECHNOLOGICAL SCHEMES OF UNDERGROUND DEVELOPMENT OF IRON ORE DEPOSITS AT THE INCREASE OF THE DIFFICULTY OF THE CONDITIONS OF THEIR FUNCTIONING

English abstract

The article is devoted to solving a complex problem that arises in the process of preparation for the development of reserves of iron ores un-derground, in the conditions of great depths of development and difficult economic conditions of operation of iron ore mining enterprises. This prob-lem concerns the development of reserves of mining sites of iron ore depos-its and consists in the need to select and put into practice the most cost-effective design solutions of structures and technological schemes of extrac-tive blocks, which represent the main production facilities for the extraction of ore. The solution to this problem requires the development of methodolo-gy, methods and specialized tools for modelling and designing the designs of technological schemes for the development of block reserves, which would allow choosing and profoundly justified and the most economical such solu-tions at the systemic level of underground mining. To solve this problem, the authors have developed and tested a system of computer simulation and de-sign of the process of mining the reserves of extractive blocks, in a methodo-logical basis and the concept of which is based systematic object-oriented approach to modelling and design. The algorithm of modelling of technolog-ical and logical schemes of working out of stocks of blocks, the procedure of development and application of technical and economic passports of ele-ments of structures of blocks, from which the variants of technological schemes of working out of their stocks are formed and the technical and economic characteristics of realization of these schemes are developed. The system of economic estimation of efficiency of working out of reserves of blocks is also developed. A promising direction for the development of this system is the expansion of its software for more detailed modelling of block elements and their technological schemes, expansion of the database of technical and economic passports of elements of block development schemes and development of graph analytics subsystem of block design sup-port, which provides a significant amount of data for economic and mathe-matical modelling of block designs and technological schemes of working out their reserves.
