Corporate Governance Codes

The article emphasizes the need to improve the mechanisms of corporate interaction of companies of the domestic mining and metallurgical complex (MMC). A brief description of the modern iron ore base of Russia is given, rational industrial operation of which implies further innovative development of iron ore raw materials processing industries, strengthening of the position of Russian metallurgical and mining companies in domestic and world markets. The main typological forms of integration interaction between metallurgical and mining segments of MMC are considered. A brief analysis of the content of the corporate governance codes used by MMC companies has been provided. Key principles of improvement of integration interaction of mining-enrichment and metallurgical in the framework of industry corporate associations are proposed. Among them — factors (conditions) of strategic planning of development of MMC business groups. Recommendations are given to improve the practice of strategic planning of supply and investment activities of mining and processing mills.

The Impact

This article summarizes the arguments within the scientific discussion on the issue of using mining machines and their life cycle. The main goal of the article is to investigate the impact of a combination of mobile and stationary mining machines and their optimal distribution in the mining process to increase the efficiency of mining and processing of raw materials. The following methods of research were focused on the use of technical indicators for the valuation efficiency of the mining process: a simulation method was used for the distribution of mining machines, comparison analysis was used for the real and past state of mining machines, and a decision tree was used as managerial instrument for optimal alternatives of mining machines. The research empirically confirms and theoretically proves that optimal distribution of mining machines and machine parks is very important for mining companies. The benefit of this research for the mining company was the new location of the machines and the combination of stationary production lines and mobile equipment. The optimal layout of the machines reduced the number of conveyor belts and improved the transfer of limestone processing to mobile devices, saving time, which was reflected in transport costs. The results can be useful for other mining companies seeking to create an optimal machine park.

The Impact

Although there has been considerable research on the impact of corporate governance on corporate voluntary disclosure, empirical evidence on how governance affects compliance with mandatory disclosure requirements is limited. We contribute to governance and disclosure literature by examining the impact of corporate governance on compliance with IFRS 7 for the banking sector in Gulf Cooperation Council (GCC). We use a self-constructed disclosure index to measure compliance with IFRS 7. We use regression analyses to examine the impact of board characteristics, audit committee characteristics and ownership structure on compliance with IFRS 7. Using a sample of 335 bank-year observations for GCC listed banks over the period 2011–2017, we report evidence that corporate governance variables affect compliance with IFRS 7. However, the significance of these variables depends on the type of the regression model used. Our findings suggest that governance matters for mandatory disclosure requirements. So to improve the level of compliance, regulators, official authorities, and policymakers should intensify their efforts toward improving corporate governance codes, following up their implementation and enhancing the enforcement mechanisms.

A Charge

To use effectively internal raw material base, JSC “Ural Steel” accomplished I category major overhaul of the blast furnace No. 2. The main purpose of the overhaul was to design a rational profile which could ensure an ability to operate with a charge containing 95 % of Mikhailovskii GOK (mining and concentrating plant) pellets having basicity of 0.5 by CaO/SiO2. The blast furnace No. 2 having useful volume of 1232 m3, was constructed by design of Danieli Corus, the Netherlands, and was blown in on December 30, 2020. In the process of guarantee tests, step-by-step increase of Mikhailovskii GOK pellets (Fetotal = 60.5 %, CaO/SiO2 = 0.5) content in the charge iron ore part was being accomplished from 55 to 95.1%. Charging of the blend containing pellets in the amount of 55% of iron ore part, was done by charging system 4OOCC + 1COOCC (Ore - Coke) with filling level 1.5 m. Under conditions of pellets part increase in the blend, the charging system was changed to decrease their content at the periphery, to increase it in the ore ridge zone and make it intermediate between periphery and the ore ridge. At the pellets share in the iron ore raw materials 0.75 the charging system was used as the following: 3OOCC + 1COOC + 1COOCC, while at the content 95.1% the following charging system was used: 2COOC + 2COOC + 1COOCC. It was noted that in the period of guarantee tests the furnace running was smooth. The average silicon content in the hot metal was 0.70% at the standard deviation 0.666. Sulfur content in the hot metal did not exceed 0.024%, the blowing and natural gas consumption figures were 2100 m3/min and 11000 m3/min correspondently, oxygen content in the blowing 26.5%, hot blowing and top smoke pressure figures were 226.5 and 109.8 KPa correspondently. The productivity of the furnace was reached as high as 2358 t/day at the specific coke rate 433 kg/t of hot metal. After guarantee tests completion, the pellets content in the iron ore part was decreased gradually from 95 down to 50%. The decreasing was made by 5% in every 6 hours of operation. Application of the mastered technology of the blast furnace No. 2 with the increased share of pellets will enable to stably supply the blast furnaces No. 1, 3 and 4 by iron ore raw materials in the proportion of 30-35% of pellets and 65-70% of sinter.
