It is in 1930 that the training of mining engineers began in Eastern Siberia on the basis of the Siberian Mining Institute (now Irkutsk National Research Technical University). In 1931 the Department of Mining Arts was organized, which later was named the Department of Mineral Deposits Development. Over the years, the Department has trained more than 7000 graduates – mining engineers, who made a huge contribution in the development of the mining industry in the Irkutsk region and neighboring territories including Mongolia. The Department has trained more than a hundred mining engineers and Masters of science for Mongolia; assisted the lecturers and professors of the Mongolian Polytechnic University (now Mongolian University of Science and Technology) in organizing the educational process for training specialists for the country's mining industry. At its different formation stages the Department of Mineral Deposits Development was headed by well-known scientists – mining engineers, who created three scientific schools for the development of coal, placer and gold deposits; the obtained scientific results were marked with two State awards of the Russian Federation, dozens of doctoral and candidate dissertations were defended and about 100 patents were received. Today, the Department super- vises the training of mining engineers in open-pit and underground mining of mineral deposits, carries out a large amount of research and design work on the orders from mining enterprises, trains academic staff, develops new technologies and technical solutions in order to improve mining operations. The Department is deeply involved in the cooperation with mining enterprises, research and design organizations, as well as with universities that train mining engineers.

This research article presents a software module for the environmental impact assessment (EIA) of open pit mines. The EIA software module has been developed based on the comprehensive examination of both country-specific (namely, Kazakhstan) and current international regulatory frameworks, legislation and EIA methodologies. EIA frameworks and methods have been critically evaluated, and mathematical models have been developed and implemented in the GIS software module ‘3D Quarry’. The proposed methodology and software module allows for optimised EIA calculations of open pit mines, aiming to minimise the negative impacts on the environment. The study presents an original methodology laid out as a basis for a software module for environmental impact assessment on atmosphere, water basins, soil and subsoil, tailored to the context of mining operations in Kazakhstan. The proposed software module offers an alternative to commercial off-the-shelf software packages currently used in the mining industry and is suitable for small mining operators in post-Soviet countries. It is anticipated that applications of the proposed software module will enable the transition to sustainable development in the Kazakh mining industry.

Mining industry faces new technological and economic challenges which need to be overcome in order to raise it to a new technological level in accordance with the ideas of Industry 4.0. Mining companies are searching for new possibilities of optimizing and automating processes, as well as for using digital technology and modern computer software to aid technological processes. Every stage of deposit management requires mining engineers, geologists, surveyors, and environment protection specialists who are involved in acquiring, storing, processing, and sharing data related to the parameters describing the deposit, its exploitation and the environment. These data include inter alia: geometries of the deposit, of the excavations, of the overburden and of the mined mineral, borders of the support pillars and of the buffer zones, mining advancements with respect to the set borders, effects of mining activities on the ground surface, documentation of landslide hazards and of the impact of mining operations on the selected elements of the environment. Therefore, over the life cycle of a deposit, modern digital technological solutions should be implemented in order to automate the processes of acquiring, sharing, processing and analyzing data related to deposit management. In accordance with this idea, the article describes the results of a measurement experiment performed in the Mikoszów open-pit granite mine (Lower Silesia, SW Poland) with the use of mobile LiDAR systems. The technology combines active sensors with automatic and global navigation system synchronized on a mobile platform in order to generate an accurate and precise geospatial 3D cloud of points.

Now spanning five simultaneous open-pit operations with exploration carried out through open pit benching, Carajás complex encompasses the world´s largest iron reserves. Open pit mining operations in the area can lead to slope instabilities with risks to personnel, equipment and production due to intense excavations in rock products of low geomechanical quality, blasting practices and heavy precipitation. Thus, an effective prediction and management of surface deformations should be a key concern for the mining operations. The ground displacement monitoring techniques in Carajás include surface measurement techniques at discrete points (total station/reflective prisms) and over area using SSR (Slope Stability Radar, a ground based radar). On the other hand, DInSAR techniques are receiving relevance in the mining industry for reasons such a synoptic and continuous coverage without the need for ground instrumentation and a point-to-point good accuracy of measuring displacements (millimeter to centimeter scale) over a dense grid. Using a stack of 33 StripMap TerraSAR-X images acquired over Carajás covering the time span from March 2012 to April 2013, a monitoring approach is discussed based on the complementary use of information provided by DInSAR (DInSAR Time-Series and Persistent Scatterer Interferometry) and surface measuring techniques (total station/prisms, ground-based radar).

A significant part of placer mineral deposits in the Arctic zone of Russia urges the need for its strategic development in the near and medium term. Applicably to underground mining of placer gold deposits, the problems of safe and efficient extraction of minerals by mines in the conditions of the Far North are considered. A substantiated choice of uncovering and mining technology for gold-bearing sand strata is proposed in the context of rational planning of mining operations associated with minimizing material and labor costs for uncovering and extracting a part of the deposit, as well as completeness of reserves depletion during the operational period. Safe parameters of structural elements of room mining systems have been determined by geomechanical assessments. Methods for additional support of the roof of mined-out rooms are proposed. The indicators of losses and dilution of gold-bearing sands in accordance with the sources of their formation were determined by the graphoanalytical method.

AbstractPoland is a country rich in lignite. The area where the lignite occurs occupies approx. 22% of the total surface area of the country. Geological resources of Polish lignite deposits are estimated at 23.5 billion Mg, but in the majority (69%) the accuracy of their identification is poor. Nevertheless the amount of coal in Polish deposits allows - at least in theory - for mining and energy production at the current level for hundreds of years to come. It is an important raw material for the energy security of the country both currently and in the future. Because the vast majority of Polish and foreign mines use an open pit method for lignite extraction the actual amount of mineral available for the extraction depends not only on the properties of the deposit but to a large extent on the method of development of the surface land above the deposit, as well as on the sensitivity of the environment in the vicinity of any future mines. After careful analysis it can be stated that only a few of the lignite deposits may be subject to cost-effective mining operations. These deposits should be subjected to special protection as a future resource base which will ensure the energy security of the country. Some examples of domestic deposits have been presented where due to the conflict resulting from the development of the area should be deleted from the Balance Sheet of Mineral Deposits because their exploitation is irrational and uneconomic. Keeping such deposits in the Balance Sheet, and the use of large numbers in the context of their resource base leads to an unwarranted sense of wealth which consequently does not encourage the protection of these deposits which may actually be subject to rational exploitation in the near future. In summary there is a need to find a compromise in order to adequately protect all natural resources including mineral deposits.

The mining industry continues to be an important sector of the Ghanaian economy, contributing to the foreign exchange, employment and socioeconomic development after the colonial period. The current trend of mining operations requires greater skills and technical knowledge because they involve sophisticated machines, dangerous chemicals and explosive mechanisms, underground operations etc. Accidents in the mines just like any occupational accident may lead to deaths, injuries, disabilities and financial losses. One of the ways of improving occupational knowledge and skills is to acquire some level of understanding of accident causation mechanism. An analytical technique which will form the basis for accident and injury epidemiological studies is therefore necessary to ensure operational safety improvement. A retrospective statistical analysis of accidents in eight gold mining companies was undertaken through measures of association, hypothesis testing, trend analysis and predictive measurements. The results of the study indicate that 20% of accident cases resulted in deaths, 30% were serious and 50% minor accidents. Underground mining increases the risk fatal accident by 1.46, morning shift increases the risk of fatal accident by 4.81 and being a contract miner increases the risk of fatal accident by 1.05. The part of body injured can predict the degree of injury by reducing the error of prediction by 40.2%. Since proportion of accident fatalities increases with increasing age of miners, it is recommended that miners with higher age should not be task with high risk jobs. It is recommended again that, miners should be given improved protective clothes to guide against occurrences of fatal incidents. Especially, clothes to cover the head and upper part of the body since they top the fatality chart and the fact that fatality is strongly associated with body part. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0720/a.php" alt="Hit counter" /></p>

The Cost

In recent years, there has been a decline in the efficiency of coal mining by traditional methods. On the one hand, the volume of coal outside the contour of the cut, which is economically impractical for open-pit mining, is increasing. On the other hand, when using underground geotechnology, the cost of production exceeds the cost of performing mining operations using open geotechnology, this is due to differences in the factors of operation of the open pit and the mine. This circumstance determines the use of open-underground technology for mining coal reserves outside the contour of the open pit as an actual and promising direction. This article describes a methodological approach based on the use of technological schemes for the preparation and treatment of reserves of powerful shallow coal seams, the justification of the parameters of combined geotechnology with a coordinated and balanced development of open and open-underground mining operations with the distribution of reserves for open and open-underground mining of coal reserves beyond the limit contour of the open pit, the preparation of excavation sites directly from its workings and the coordination of production capacity and the speed of their development. Its application will increase the production capacity of the coal mining complex without additional environmental burden and will provide an increased return on investment.

Mining Coal

Conditions for the coal extraction under the built-up areas and natural objects in the Russian Federation are fully regulated by the Rules for the protection of structures and natural objects from the harmful effect of the underground mining at the coal deposits. Determination of the degree of danger of effecting mining operations on these objects, and the choice of measures for their protection are carried out based on the calculation of the earth surface deformations. The purpose of the work is to develop proposals for the modernization of the current regulatory and methodological document based on the analysis of the compliance of its provisions with the modern conditions of the deposits underground mining. Experience of applying the document under consideration in the modern conditions of the development of coal deposits showed that many of its provisions contain a number of inaccuracies, in particular: ambiguity in determining the boundaries of the zone of dangerous influence of the underground mining; lack of a methodology for predicting the period of damping of the process of earth surface damage after stopping the working face; limited conditions for determining the standard deformation indicators for civil buildings, etc. In addition, in this document, only the underground method of mining coal seams is considered, while the more promising is a combined development, combining underground and open-pit methods. The problem of inconsistency of the current rules provisions with the modern conditions can have a very negative effect on the safe state of the undermined objects. Based on the analysis of the identified shortcomings, a number of proposals for improving the rules was developed. In particular, it was proposed to expand them by including the rules and regulations of the combined method of deposits development. It is also required to update the normative and methodological parts of the document bringing them in line with the modern conditions of deposit development considering the accumulated experience of the objects undermining, and the results of the latest studies of rock mass deformation.

The international geological community has acknowledged Muruntau gold deposit as the greatest discovery in the mid-to-late 20th century. Muruntau mine field holds the total appraised resource potential of more than 4.5 thousand tons of gold. Hydrometallurgical plant GMZ-3 implements gold-ore processing by gravitational sedimentation and adsorption. The technological and instrumental modernization of the gold processing circuit toward its higher capacity, gold recovery and thoroughness are the important aspects of production improvement and cost reduction. The developed and introduced ore milling flowchart provides replacement of the second milling stage pumps by higher-capacity pumps backed up with additional cyclones. Aiming to ensure stable gold production at plants GMZ-2 and GMZ-3, Navoi MMC’s experts accomplished the feasibility study of mining operations in Chukurkuduk and Turbai deposits in 2020. The growth prospects for open pit mining in Murunatu–Myutenbai fields after 2060 are estimated using the model of optimized ultimate pit limit design at the gold price of USD 1500/t. The model ultimate pit limit embraces all probable reserves as per the detailed 2D seismic data as of early 2020, including proven reserves intended for open pit and underground mining. The gold ore appraisal and the expansion program elaborated for Muruntau gold mining and refining integrated works in joint Muruntau–Myutenbai field, through implementation of operation phases V and further make it possible to forecast stable performance up to 2030–2050.

Open mining development is the cheapest method, because it uses powerful production equipment, which allows a large amount of minerals to be excavated during a shift. Working conditions in open development are less dangerous for the health of workers, and a smaller number of supervisory personnel than in underground mining is required. In the process of open development, stripping works are first carried out, i.e. the removal of the empty rocks covering the deposit. Constantly growing requirements for energy sources, metal ores and building materials cause the need for intensive development of the mining industry. There is a rejection of significant areas for the development of minerals in an open and closed way. The causes of degradation are both the mining of minerals, as well as construction, the placement of production and consumption wastes in the natural environment. Changes in the components of the environment are observed as a result of direct or indirect influence of mining enterprises activities. This requires an analysis of the entire complex of geo-environmental problems of open mining and the identification of the most urgent ways to solve them.
