Currently, digitalization and widespread adoption of digital technologies are significantly changing people's activities in many areas. Digital technologies provide automation of business processes, data management, analytics, they support strategic decision-making and dictate the need to introduce new approaches to doing business in order to increase its efficiency and profitability, as well as to ensure sustainability of companies' development in modern conditions. It needs to be especially mentioned how the big data processing and analysis technologies and other Industry 4.0 achievements are introduced in the mining industry. The use of big data analytical systems in modern production, including the mining industry, provides an integrated approach to processing and analyzing a large amount of information. It also provides organizations with significant advantages reflected at various levels of management and strategic decision-making. The prospects for implementation and development of these digital solutions currently look very encouraging. Effective management of these processes provides companies with significant opportunities and advantages, allowing them to increase competitiveness, optimize the use of resources and increase the efficiency of their business as a whole.

This article presents up-to-date, complementary information from the marketing reviews of the industry for the production and use of magnesium oxide conducted by global analytical companies. It shows a steady growth in the global demand for MgO, observed over the past decade and driven not only by the traditional industries, but also by emerging innovative areas. Global trends indicate an increase in the production of magnesium oxide and the development of new technologies for its extraction. This area provides an opportunity to improve the product quality, increase production efficiency and expand market opportunities due to the active development of high-tech sectors of the economy. Based on marketing analyses, growing competition is revealed both in the global magnesium oxide market in general and in the Russian Federation in particular, which encourages manufacturers to develop innovative products and marketing strategies to retain and expand their share in the market. At the same time, a potential instability has been identified in the magnesia industry, manifested in some world leaders, due to the new environmental requirements that cause restrictions in production, which may lead to problems in supplies around the world.

This article discusses the need for the development of Russia's mineral and raw material base to support the country's high-tech economy. Special attention is given to prospecting and mining of strategically important types of raw materials, such as titanium, tungsten, lithium, and others. The importance of securing resources from domestic sources, minimizing dependence on imports, is emphasized. The article describes remote survey methods, specifically the use of Earth remote sensing data, i.e. the satellite images, for prospecting and assessment of potential deposits. An analysis of satellite data of the Murmansk Oblast is conducted to identify the potential mineralization nodes. The methods used include interpretation of images using geological indexes. With their help, zones of geological interest can be identified, which can later be used in a full range of geological exploration activities.

Studies of the spatial and temporal patterns of seismic activity development in the undermined rock mass have been performed at the Rasvumchorr Mine. The main cluster associated with generation of rock caving in the overhang part has been identified. It is established that caving was developing gradually from the depth of the rock mass towards the surface. The results are presented of estimating the quantitative parameters of the seismic process in the undermined rock stratum, i.e. the energy index and the cumulative apparent volume, which reflect the stress changes in the rock mass. Ranges of the stable state of the rock mass, when the overhang rocks do not cave, as well as the ranges of active fracturing and caving of the overhang rocks have been identified. Changes in these parameters for the studied area of the deposit reflect the loading and strength degradation stages in the rock mass. The results of this study correlate well with the data on actual caving of the undermined rock strata. This work is a continuation of the authors' research into the problem of identifying spatial and temporal patterns in the development of undermined rock strata cavings in the tectonically stressed Khibiny massif.

Digitalization of enterprise management using Russian software is the main trend in the development of the country's mining sector. Sharp fluctuations in demand and prices in the mineral markets, as well as the development of technical tools for mechanization and automation of technological processes along with a systematic increase in their cost affect the financial performance of mining companies. This determines the need for a rapid adoption of technical, technological and organizational decisions, which, along with the requirements of the company's owners and regulators to obtain prompt, reliable and the most complete information about the production process explains the urgent need for the prompt introduction of digital control systems for mining operations. In the article the authors describe an algorithm to design a digital model of the mining and geological system, including a digital geological model of the deposit, digital models of mine workings and the surface topography, based on the experience of creating three-dimensional digital models of complex-structured coal deposits. The basic software suite for designing a digital management system for mining operations is the MINEFRAME mining and geological information system developed at the Mining Institute of the Kola Scientific Center of the Russian Academy of Sciences. MINEFRAME allows to perform a full range of tasks aimed at creation of a digital 3D model of the mining and geological system for a coal deposit with the possibility to account for the complex bedding in the modelling. High accuracy and correctness of the input geological sampling data is achieved by means of tools to check for errors in the tables of borehole collar coordinates, inclinometry and sampling. The wireframe modelling methods implemented in MINEFRAME provide the possibility to create wireframe models of seams with high detail in the fracture zones.

Modern business solutions set a trend towards integrating digital technologies into all areas of corporate organization. Digitalization plays a key role in modern business, enabling companies to increase the process efficiency, reduce costs, and improve product quality and maintenance efficiency. It also helps to be competitive in the marketplace and adapt to changing customer demands. In order to maximize the effects of implementing digitalization, the transformation needs to encompass not only the local business processes and business models, but also the corporate culture. The study analyses the process of exploring the digitalization potential for a modular mobile plant (mini-plant) that produces non-explosive components of emulsion explosives developed by AZOTTECH. The paper identifies the key points necessary for successful implementation of the digitalization process at the mini-plant, which can serve as a basis for designing a digital twin implementation strategy. It also describes application of a modern approach in performance evaluation using the matrix of business benefits.

One of the major tasks in carrying out open-pit mining operations is timely and high quality maintenance and repair of mining equipment, in particular, mechanical shovels, which secures a required availability level. The most loaded are the lift and pressure drives of the shovel's working attachments, which significantly increases the risk of failure of their components. An adequate assessment of the loads acting on these drives through analyzing the changes in currents and voltages of their motors makes it possible to adjust the time between maintenance. In the course of the study, the representative points of the following three lumped working processes were obtained within the working cycle of 26.75 s: excavating; platform rotation with simultaneous movement of the shovel from the upper point of the path to the unloading point; reverse movement of the platform rotation mechanism with the returning and its positioning of the working attachment to the initial position. Changes in forces acting on the ropes of the lifting winch of the shovel were determined based on the evaluation of the obtained layout of the working attachment positions for the EKG-18R mechanical shovel and taking into account the driving and motion resistance forces within the working cycle. Analysis of the obtained force values acting on the ropes of the lifting winch at the three linear excavation paths with the inclination angles of 60, 70 and 80° has shown that the lowest forces in the lifting winch rope occur at the closest path with the angle of 60°. The received data will allow not only to select a rational path and the angle of bench mining, but also to adjust the time between maintenance according to the actual operating time of the lifting, pressure and movement drives.

The received data will allow not only to select a rational path and the angle of bench mining, but also to adjust the time between maintenance according to the actual operating time of the lifting, pressure and movement drives.","PeriodicalId":506182,"journal":{"name":"Mining Industry Journal (Gornay Promishlennost)","volume":"8 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141661526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
