Abstract
The object of research is an audit, which should be carried out to assess and feasibility of further development of new deposits of flux raw materials for the needs of the metallurgical industry and attracting potential investors. Some of the most problematic areas are limited by the economic potential of open pits for expanded reproduction and the difficulty of attracting investments due to the low investment attractiveness of the deposits.The analysis of the current state of deposits of flux raw materials is carried out on the example of Ukraine. The main characteristics of the low investment attractiveness of limestone and dolomite quarries are determined. The need for an in-depth audit of the financial and economic activities of a quarry is determined, taking into account the specifics of the extraction of flux raw materialsIn the course of the study, system modeling tools are used to calculate the feasibility of developing new sites. The primary stages of the audit are shown to determine the feasibility of further development of new sections of flux raw materials, the production volumes of which will meet the needs of the metallurgical industry, subject to a competitive price of fluxes on the market. These stages provide for an assessment of the feasibility of further development of sections of flux raw materials and an analysis of the throughput of narrow links of the quarry to determine the amount of investment in making management decisions on these issues. For their implementation, an economic and mathematical model for optimizing the parameters is proposed to determine the economic feasibility of developing flux feedstock reserves in new areas, if the alternative is the loss of reserves in the underground resources. This ensures a reduction in the labor intensity of the check and its terms.In comparison with similar well-known methods, the proposed approaches will reduce the amount of audit costs paid by the audit customer.
Highlights
In modern economic conditions in a number of countries the problem of further development of deposits of limestone and dolomite for the needs of the metallurgical industry, glass, sugar and other enterprises remains urgent
Limestones and dolomites of similar quality are found in a number of other regions of the country, including in the central and western regions, but due to the absence of a metallurgical industry here, they were explored and taken into account by the state balance as raw materials for the needs of the sugar industry and for other purposes that are not designed for volume of consumption of metallurgical enterprises
I=1 where n – the number of accounted processes where the cost increases due to the development of new sites. It directly follows from (2) that the development of new sites is impractical if it leads to an increase in the cost of extracting flux raw materials in the open pit as a whole
Summary
In modern economic conditions in a number of countries the problem of further development of deposits of limestone and dolomite (flux raw material) for the needs of the metallurgical industry, glass, sugar and other enterprises remains urgent. There are deposits of similar limestone and dolomite with reserves of tens – hundreds of millions of tons, where no detailed exploration work has been carried out These are deposits in the Vinnitsa region, a number of sites in the Ternopil and Khmelnytskyi regions [1, 2]. As well as the solution of theoretical and practical problems of improving the organizational and economic mechanism for the development of quarry reserves Under such conditions, a team of specialists should be formed to conduct the audit. Conducting an audit using system modeling tools when developing new sections of flux raw materials to reduce labor intensity and shorten the inspection time is relevant and requires further consideration
