Hryhoriev Y. Оptimization of mine operation regime in the system "pit-technogenic deposit".

The thesis is devoted to the actual scientific task, which is to regulate the regime of mining operations at the complex development of mineral resources according to the minerals market demand with combined geogenic and technogenic deposit development. The technological principles of technogenic deposits formation are originated in this work. Technology of technogenic deposits formation was created according to these principles, based on filling in the deposits grooves mounting system. The influence of the form of the foundation of technogenic deposits for the specific costs of its formation is discovered. The optimal number of tiers of technogenic deposit, depending of its volume, is identified. The influence of the combined geogenic and technogenic deposit development on the regime of mining operations was discovered and the criterion for its determination in the complex mining deposits in market conditions was developed. The method, based on the idea of regime regulation of mining operations in the system "open pit-technogenic deposit" by storing excess volumes in periods of falling demand and development in the period of the increase in demand, was developed. The developed technology of technogenic deposits formation is introduced in the design of low-grade ores warehousing of the open pit "Pivdenniy" of mine office PJSC "ARCELORMITTAL Kryvyi Rih". The expected economic effect of the application of research results is 1,977,000 UAH. Industry - Mining (technical sciences).
