The demand for minerals is set to increase in the future due to the global competition, industrialization in the developing countries, digitalization of the developed economies as well as the social and economic shocks in the course of a deep transformation of the international economic order. Dependence on the critical raw materials may soon replace the dependence on oil and gas. A reliable and sustainable supply of both primary and secondary raw materials, especially of the critical raw materials for the key technologies and strategic sectors such as the renewable energy, electric mobility, digital technologies, space and defense, is a prerequisite for achieving national security and independence. The new EU Industrial Strategy addresses security and sustainable development and calls for active action on critical raw materials and creation of sector-specific raw material alliances. This EU policy pursues a strategy of diversification in providing non-energy raw materials for EU value chains and ensuring the social welfare. Diversification of supply is related to reducing the dependencies in all areas by supplying primary raw materials from the EU, by increasing the supply of secondary raw materials through efficient use of resources, and by finding alternatives to scarce raw materials. One of the priority actions was to create a list of critical raw materials at the EU level.
由于全球竞争、发展中国家的工业化、发达经济体的数字化以及国际经济秩序深刻变革过程中的社会经济冲击,未来对矿产的需求将会增加。对关键原材料的依赖可能很快取代对石油和天然气的依赖。可靠和可持续的初级和次级原材料供应,特别是可再生能源、电动交通、数字技术、空间和国防等关键技术和战略部门的关键原材料供应,是实现国家安全和独立的先决条件。新的欧盟工业战略涉及安全和可持续发展,并呼吁对关键原材料采取积极行动,并建立特定部门的原材料联盟。这一欧盟政策奉行多元化战略,为欧盟价值链提供非能源原材料,并确保社会福利。供应多样化是指通过从欧盟供应初级原材料,通过有效利用资源增加二级原材料的供应,以及通过寻找稀缺原材料的替代品,来减少对所有领域的依赖。其中一项优先行动是在欧盟层面制定一份关键原材料清单。

The paper provides evidence that the existing standardized design concept of power supply systems for the mine sites inherently involves existence of an electrical shock hazard to humans when touching the phase of the network. This hazard is caused by the active and capacitive conductance of the insulation due to grounding of the central cores of the flexible shielded mining cables. The functional inefficiency of the ground fault protection used in the mining industry has been proved, including the cases of mine electric networks with high power consumption. An alternative concept was justified to design the power supply system for a mine section electric network, which excludes grounding of the central cores of the flexible cables. This approach implements the principle of selective shutoff protection of the electrical consumers in the mine section using local means to control the condition of insulation in the power connections.
该论文提供了证据,证明现有的矿场供电系统标准化设计概念本质上涉及到当接触网络相位时对人类的电击危险。这种危险是由柔性屏蔽采矿电缆的中心芯接地引起的绝缘的有源和电容电导引起的。采矿业中使用的接地故障保护的功能效率已被证明,包括高功耗矿井电网的情况。另一种概念被证明是合理的,用于设计矿区电网的供电系统,该系统不包括柔性电缆中心芯的接地。这种方法实现了对矿区用电设备的选择性关闭保护原则,使用本地方法来控制电源连接中的绝缘状况。

The article summarizes and analyzes the resources, supplies and markets of the world's main natural resource, i.e. freshwater. The materials prepared and published in the article is based on the author's own analytical and field work. Resources of the high quality natural freshwater are tight: they are and will continue to be subject to ever-increasing demand. Over the last 80 years the total consumption of fresh water has increased by 10 times while the population has grown by a factor of 2.5. The present-day world economy is water-dependent. Main consumption of water is defined by the following four sectors of the global economy: agriculture, energy, industrial production and domestic water consumption. Growth in energy production and consumption is directly linked to increased water consumption. Water supply, wastewater collection and treatment are the leaders in capital gains. Privatization of the world's natural freshwater resources is underway. The task of total dependence of arid states on product supplies from the Golden Billion countries is being resolved. The main natural resource and asset of the Russian Federation, i.e. the water resources, is completely missing from the strategies and doctrines of the Ministry of Natural Resources of the Russian Federation.
本文对世界主要自然资源淡水的资源、供应和市场进行了总结和分析。文章中准备和发表的材料是基于作者自己的分析和实地工作。高质量的天然淡水资源紧张:它们现在和将继续受到不断增长的需求的影响。在过去的80年里,淡水的总消耗量增加了10倍,而人口增长了2.5倍。当今世界经济依赖水。水的主要消耗由全球经济的以下四个部门定义:农业、能源、工业生产和生活用水。能源生产和消费的增长与水消耗的增加直接相关。供水、废水收集和处理是资本收益的领导者。世界自然淡水资源的私有化正在进行中。干旱国家完全依赖黄金十亿国家产品供应的任务正在解决。俄罗斯联邦的主要自然资源和资产,即水资源,在俄罗斯联邦自然资源部的战略和理论中完全缺失。

Modern market conditions are characterized with volatility of the prices and demand for raw materials. Therefore the development of many major mineral deposits in the Russian Federation requires elaboration of the company's development strategy which involves solving complex design tasks to ensure production efficiency in complex geological and mining conditions with proper account of natural and environmental constraints as well as the company's sustainability and viability goals over a long period of time. The article presents one of the approaches that can be used when selecting the development strategy of a mining company with account of environmental constraints. Using a limestone deposit, which name has been changed due to the confidentiality conditions, as an example, the article describes options for technological solutions related to dewatering of its reserves. Implementation of these solutions is aimed at developing and extending the lifetime of the mining operation, mitigating environmental risks and implementing environmental protection measures. Systematization of methods to protect the open pit from ground waters is made based on the complicating factors. An aggregated technical and economic assessment of the presented options of strategic decisions is given.
现代市场条件的特点是原材料价格和需求的波动。因此,俄罗斯联邦许多主要矿床的开发需要制定公司的开发战略,包括解决复杂的设计任务,以确保在复杂的地质和采矿条件下的生产效率,同时适当考虑自然和环境限制,以及公司长期的可持续性和可行性目标一段时间。本文提出了在考虑环境约束的情况下选择矿业公司发展战略时可以使用的方法之一。文章以一个石灰岩矿床为例,描述了与储量脱水相关的技术解决方案选项,该矿床的名称因保密条件而更改。这些解决方案的实施旨在发展和延长采矿作业的寿命,减轻环境风险并实施环境保护措施。根据这些复杂因素,对露天矿地下水保护方法进行了系统化。对所提出的战略决策备选方案进行了综合技术和经济评估。

Description of the main theme. Before the Republic of Tyva, the modern conditions of development have put forward the challenges of intensifying the development of natural resources to improve living standards and reduce unemployment. Since coal is the main wealth of the interior of Tyva, it is necessary to find ways to involve this resource in economic circulation. Object problems. At present, a coal-mining territory is being formed in Tyva and the volume of coal production is growing dynamically. There are high risks. Purpose of the study. Analysis and systematization of the challenges and risks of a large-scale increase in coal production in Tyva. Basic methods of analysis. Methods of systemic, economic and statistical analysis, classification were used. The research was based on statistical and analytical data for Russia and the Republic of Tuva and internet resources. Research results. The scientific novelty of the study consists of the analysis of the development of coal mining in the regions of the Russian Federation, systematization of risks arising in the formation of coal-industrial territory in Tyva. Natural, anthropogenic, technogenic and socio-economic risks are identified, differing in the source of their occurrence. Ecological risks from anthropogenic and technogenic risks are highlighted. The ways of reducing the possible environmental load are substantiated. Conclusions. Based on the results of the study, it was concluded that in order to reduce the lag in the parameters of socio-economic processes in Tyva, one of the effective ways is the formation of a coal mining area. This implies the creation of an energy-chemical complex for coal processing and the production of a wide range of coal chemistry products, an increase in coal export volumes after the construction of the railway. To eliminate the high risks of this strategic direction of regional development, it is proposed to implement a number of innovative sustainable technology, systematic monitoring of the state of coal mining territories.
对主题的描述。在特瓦共和国之前,现代发展条件提出了加强自然资源开发以提高生活水平和减少失业的挑战。由于煤炭是特瓦内陆的主要财富,因此有必要寻找将煤炭资源纳入经济循环的途径。对象的问题。目前,特瓦正在形成一个采煤区,煤炭产量正在动态增长。风险很高。研究目的:对蒂瓦大规模增加煤炭产量的挑战和风险进行分析和系统化。分析的基本方法。采用系统分析、经济分析和统计分析方法进行分类。这项研究是基于俄罗斯和图瓦共和国的统计和分析数据以及互联网资源。研究的结果。这项研究在科学上的新颖之处包括分析俄罗斯联邦各地区的煤炭开采发展情况,将特瓦煤工业地区形成过程中产生的风险系统化。确定了自然风险、人为风险、技术风险和社会经济风险,它们的发生来源各不相同。人为和技术风险的生态风险突出。提出了减少可能的环境负荷的方法。结论。根据研究结果,得出结论认为,为了减少特瓦社会经济过程参数的滞后性,有效的途径之一是形成一个煤矿矿区。这意味着要建立一个能源化学综合设施,用于煤炭加工和生产各种各样的煤炭化学产品,并在铁路建成后增加煤炭出口量。为了消除这一区域发展战略方向的高风险,建议实施一些创新的可持续技术,对国家的煤矿开采领土进行系统监测。

Creation of mine development plans for mining operations in the ferrous and non-ferrous metals industry is a timeconsuming and creative process that requires high levels of specialist expertise, especially in manual planning, where it is quite difficult to assess the impact of decisions made hic et nunc on the future development of the company. Application of mining and geological systems in planning makes it possible to simulate and assess many different options in mine development within a short period time and with sufficiently high reliability. These systems allow planning specialists to make more informed and correct decisions without the fear that these decisions may lead to deterioration of open pits or mines. The article describes the course of project implementation to transform the business processes of mine planning using mining and geological information system by Dassault Systemes at the METALLOINVEST Group of Companies as exemplified by the Mikhailovsky GOK Lebedinsky GOK mines.
为黑色金属和有色金属工业的采矿作业制定矿山发展计划是一个耗时和创造性的过程,需要高水平的专业知识,特别是在手工规划方面,很难评估这些决定对公司未来发展的影响。在规划中应用采矿和地质系统,可以在短时间内以足够高的可靠性模拟和评估矿山开发中的许多不同选择。这些系统使规划专家能够做出更明智和正确的决策,而不必担心这些决策可能导致露天矿或矿山的恶化。本文描述了项目实施过程,以米哈伊洛夫斯基GOK列别金斯基GOK矿山为例,利用达索系统在METALLOINVEST集团公司的采矿和地质信息系统改造矿山规划的业务流程。
