Topical problems concerning both methods and economy to develop mineral deposits

Abstract

Purpose. Development of mining enterprises adaptation to changes in conjuncture of a product market relying upon its competitiveness while reducing expenditures connected with mineral stock extraction at the expense of mining operation schedule reorganization in accordance with market demand for their products.Methods. Methodological approach to provide output competitiveness in the context of its adaptation to market demand has been substantiated with the use of correlation analysis technique taking into consideration variability of outgoing data and their uncertainty. A technique to support competitive product advantages has been identified on the basis of operations function of mining complex since the advantages depend heavily on the expenses connected with crude ore. Cost changes effected by a market demand have been estimated basing upon feasibility analysis of operations of open pits selected to be considered. Findings.Relations between crude ore mining, prime cost of ore mining and processing enterprise product of Ukraine and market demand for their output have been determined. The current open pit expenditures, connected with ore bed mining, have been specified; process solutions, concerning the operating mining complex modernization, has been substantiated basing upon them. Extraction system effect on the mining complex technological adaptation to lower demand for manganese ore has been stated.Originality. Scientific and application foundations to obtain competitive advantages for the product manufactured by mining and processing enterprises by means of technological adaptation of mining complexes to market demand have been developed. Adaptation instruments of the complexes have been estimated with the help of the production function. Methodological approach to plan crude ore prime cost, basing upon expenditures, connected with overburden operations, has been improved. Practical implications.In the context of Pivnichnyi and Zaporizkyi open pits, the effect of extraction volumes on the mined ore prime cost has been determined; the effect has been involved to substantiate economically the expedient system for ore bench mining. Production function of Pivnichnyi open pit has been defined. Its analysis results helped formulate recommendations concerning labour shedding and production increase.

Determination of economically viable option of liquidation the consequences of external dump deformation

“…To determine the economic indicators of options for the development of works on the dump the indicator PVI (Present Value of Investment) was used [26], which is calculated to obtain an idea of the current value of the total investment costs of the enterprise over the years. The decrease in this indicator against the background of an increase in discounted incomes from investments indicates an increase in their efficiency.…”

Managing mining enterprise productivity by open pit reconstruction

“…Using the above technological approaches in the view of the discrepancy of the capacity of applied complexes of mining operations at manganese open pits of the Pokrovsky MPE to the volume of market demand for manganese concentrate, the mining method of overburden massif under the combined system is improved [12,13]. This improvement involves:…”

Promotion of the EIA Subsystem of the 3D-Quarry Web Application

“…In the context of the transformation of the modern business environment, the use of digital technologies in information processing, the adoption of optimized design decisions, as well as the possibility of their timely adjustment, makes it possible to use both time and money resources more efficiently. Accordingly, to increase the efficiency of the enterprise [7], [8].…”
