The authors analyze the industrial revolutions – from Society 1.0 to Society 5.0. Today, the Society 4.0 Project implementation is under way; it covers the period of mass computerization and technology development, as well as optimization of the average resources consumption per capita. Moreover, the advanced economies of the world go ahead with the development and implementation of the Society 5.0 conception, which means breaking of digital technologies into nearly all spheres of our life. The article discusses promising technologies and areas spurring the implementation of the Industry-4.0 Program in the Russian coal sector, as well as the classification of the main elements of the Industry-4.0 Program for basic processes of mining supplemented with two important areas: Safety-in-Operation and Manufacture of Novel Mining and Transport Machinery with the Use of Digitalization Elements. Actual case studies of the Industry-4.0 Project elements implementation in the RF coal sector by mining area. The article also contains a forecast of the main performance and economic indices of the Russian coal sector development for the period up to 2040 in conditions of the Industry-4.0 Program implementation, including such indices as coal output and exports, number of production personnel on mine books, and output per man in the sector.

The article describes the solution of the scientific and practical task of calculating and developing the parameters of fixing for the workings and chambers of the deep horizons of the copper-pyrite deposit. Geomechanical conditions of the deposit exceed the limits of the normative documentation of the Russian Federation. The exceeding value of the horizontal stress components over the gravitational vertical ones did not allow to apply the normative methodology for calculating of the supports of mine workings. An integrated approach using various scientific methods has made it possible to solve this problem. Methods of analytical calculations were used to determine the stress field vertical component parameters and the overall parameters of mine workings fastening. The CAE Fidesys software complex was used to calculate a limit state design zone around the workings with various shapes and sizes. The rating approach to the problem of strength and fracture of the massif allowed to generalize rock characteristics used for calculations and to unify the final results. Analysis of existing experiences of the support usage at the mine has made it possible to select the optimal type of the support for the calculated conditions. The calculation through the finite element method was carried out in two stages. This allowed us to reduce slightly the nomenclature of the sections used for calculations. The use of the scripting language built into CAE Fidesys allowed to calculate and process more than two hundred and fifty different combination variants of the shape and dimensions of the workings, of the type and characteristics of the rock massif and of the estimated depth of the workings. This flexible approach allowed to solve the task within a short time and with the minimal participation of specialists.

The article presents a case study of field geological training for schoolchildren within the framework of occupational guidance programs implemented on the basis of the Interuniversity Academic Center of Mining and Geological Profession Navigation of the RAS State Geological Museum with the support of the Academy of Mining Sciences. Field training is aimed at the formation of the schoolchildren’s interest to mining and geological professions and research areas. In the practical aspect it enables children to make their own collections of rocks, minerals and fossils; to learn how to make records in a consistent manner and to collect samples and materials, and to develop skills of working in field conditions, to choose their research areas for the future. Another important aspect of the described measures is the development of the general scope of interests of the young people providing them with the knowledge on the history and culture of the attended regions

The authors have performed the analysis of the available indices characterizing a set of rock properties and behavior expressed in terms of the degree and nature of fracturing. The indices applicability has been estimated for only some particular rocks. A method for the integral criterion is proposed, which characterizes the total complexity of rock breakage along the total length of a mine working, its section or a mine. The authors propose an index of rock strength equivalent characterizing the average strength of rock, with due account for individual rock behavior in different sections of an underground working.
