The stress-and-strain state of the natural stress field was determined using the PRESS 3D URAL dedicated software. Studies to ensure geodynamic safety were carried out based on a 3D geodynamic model and using three types of models, i.e. the block (geological and structural), geodynamic and mining-geodynamic model of the deposit (mine field or its segment). The results obtained allow making a conclusion about viability of applying analytical methods to calculate the stressed state of blocky rock mass and, in particular, application of the PRESS 3D URAL dedicated software as a digital geomechanical twin, as well as the need to continue and expand research activities in this direction to enhance safety of mining operations.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46437812","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}

The purpose of this article is to identify the competitive advantages and the role of import substitution in Russia. Before 2014, most of the fleet in all mining companies was made up of imported equipment. Given the political circumstances after 2014, the situation in the country has changed, and the Russian mining industry began to replace foreign machinery with domestic mixing and charging machines, which are not inferior in quality, but more competitive in price. There are already more than 10 manufacturers of mixing and charging equipment in Russia, including the following companies: AZOTTECH LLC (Berezniki), NIPIGORMASH JSC (Yekaterinburg), Research Institute of Mechanization (Krasnoarmeysk), SpetsTransMash LLC (Novokuznetsk) and others.

By removing its relative transport isolation not only with the cross-border territories, but also with the neighbouring Russian regions, the republic would be able to unlock its potential for economic development, including the use of its natural resources. Extending the Kuragino-Kyzyl railway project to the Mongolian border is one of the main targets in creation of the backbone infrastructure facilities within the West-East international transport corridor of the Republic of Tuva's individual social and economic development programme. In order to assess the viability of developing some of the deposits in Tyva, which are located at the border with Mongolia, a feasibility study was performed to assess the development of the Tastyg spodumene pegmatite deposit. Preliminary calculations show that the capital investments of RUB 4,200 million (as of 2021) in the development of the Tastyg spodumene pegmatite deposit will be recoverable. In addition, the annual budget allocations are estimated to reach RUB 710 million. The social effects of this project include the construction of a motor road and a power transmission line to the remotely located district of Tere-Khol, which is currently one of the hardtoreach areas of the Republic.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44374388","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}

The morphostructural groups of oval outlines identified on the isolinear distribution schemes of the top and bottom of the Tunguska series are considered as a marker of the “ring” structures development. These structures are developed along the boundaries of mine fields. Their formation took place in the period following the ore formation. Individual tectonic disturbances developed inside the “ring” structures and along their boundaries can be traced down to the occurrence depth of the ore-bearing intrusions and ore bodies. The “ring” structures were formed in the southwestern part of the Talnakh ore cluster as a result of left-sided strike-slip faults, which were accompanied by east-bound torsions. The “ring” structures are morphotectonic blocks that are distinguished by maximum tension indicators. As a result of the research, it was found that the “ring” structures are the marking signs of geodynamically active structures of the strike-slip and the oblique-slip kinematics with a high density of disjunctive disturbances, in which high risks in development of dangerous geodynamic processes and phenomena are possible in zones adjacent to the mine fields.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42275079","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}

However, the European and American companies are being replaced by Chinese corporations, which also have the necessary technologies and equipment for oil and gas production in hard-to-recover fields. It should also be noted that the European Union plans to reduce the volume of natural gas supplied from the Russian Federation and to build new terminals for the imported LNG, and has already abandoned the project to pump gas through the Nord Stream-2 pipeline. In response to these Western initiatives, the Russian authorities are likely to undertake a number of steps to re-route the natural gas supplies to China and build a gas pipeline to India.

The key point is that improvement of the energy efficiency in application of this method depends on enhancement of theoretical knowledge on physical phenomena and regularities in technical devices. The objective of this research is to clarify the cause-and-effect relations and to explain regularities of physical phenomena in devices that convert solar power into electric energy in terms of fundamental axioms of the quantum theory in molecular systems, which would open up the possibilities to enhance the energy efficiency of solar power engineering. The paper analyzes the notions that are common in the scientific and educational literature and are related to electric current, free and superfluous electrons in atoms, and the motion of charged particles under the action of electric current. The scientific novelty consists in conceptualization of scientific statements in the fields of physics, electrical engineering and chemistry. A new concept of the energy phenomena in multilayer structures of semiconductor-based devices for conversion of solar radiation into the electric current has been formed for the first time ever. A schematic diagram of electric power generation upon solar irradiation of these devices is presented. The electric current in a closed circuit is the total solar energy absorbed by the valence electrons of the device's semiconductors, which they emit in a concentrated manner within a closed electric circuit. The practical value of the new knowledge lies in improving the professional competences and enhancing the energy efficiency of technological devices used to convert solar energy into electric current.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49067182","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}

At the same time, leaving pillars made up of fragile ores exposed to significant compressive stresses poses a risk of dynamic formation pressure. Due to the design features of the mining method and safety regulations, it is not possible to access the drift pillar from the rising side, which limits the ability to make a meaningful instrumental forecast of the rock-bump hazard. Therefore, it is advisable to use digital twins to predict the rock-bump hazard of the drift pillars. The article describes the experience gained by the VNIMI Institute in using the PRESS 3D URAL dedicated software (Polygore LLC, St. Petersburg) and the FIDESYS software package (Fidesys, Moscow) for a comprehensive assessment of the stress-and-strain state and rock-bump hazardous condition of the drift pillar. The first stage included numerical evaluation of the natural tectonic stress field using the PRESS 3D URAL software. At the second stage, an assessment of the man-made stress-and-strain state of the rock mass and the ore drift pillar was performed using the FIDESYS software package during underground mining with the heading-and-stall method. The final stage involved a prediction of the rock-bump hazard of the ore pillar using data on the ore strength properties.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47635955","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}
