“…As an example, let us consider the following case: activation of subsidence processes in the north of Kuzbass. Kuzbass is a mining-industrial region of Russia with an unfavorable environmental situation [65][66][67][68]. Here, the Sudzhenskaya and the Anzherskaya mines were working out Tenth, Andreevsky, and Koksovy seams.…”

The hypothesis of the piston effect during mine gas migration caused by fault reactivation was studied, with the use of computer modeling, to explain cases of a sudden appearance of mine gases on the earth surface in coal mining areas. The study is based on the factual data of the mode and amplitudes of subsidence along faults during mining, the morphology of the fault planes, and the theoretical ideas about the discrete nature of the fault wall displacement along uneven contact surfaces. It is taken into account that the walls of the fault, due to the asperity types “ridge” and “sag”, form contacts of the “ridge–ridge” and “ridge–sag” patterns. This study examines the situation where gas pressure in the fracture space can sharply increase due to the jerky displacement of reactivated tectonic fault walls with a rough fault plane. It is assumed that, in the first phase of reactivation, the fracture space expands as a result of the displacer opening and the fact that fault plane asperities engage in the “ridge–ridge” type of contact. With the subsequent relative displacement of the fault walls in the second phase of reactivation, the contact changes into the “ridge–sag” type and a sharp reduction in the fracture space volume occurs. It is shown that a “piston effect” emerges due to the reduction in fracture space and that it promotes an increase in gas pressure and stimulates gas movement to the surface through the available channels. The resulting “piston effects” may also be responsible for the suddenly raised gas content recorded in the air of surface structures and recurrent mine gas migration onto the surface. The findings expand our understanding of the sudden gasification of the earth surface and living spaces in coal mining areas and contribute to the understanding of the gas migration process, thereby helping to monitor hazards.

“…To control the grain size, it is proposed to improve the method of control of grinding balls [15] and introduce new technologies for the manufacture and diagnostics of crusher wear [16]. The possibilities of quality control through the introduction of automated systems in the mining industry are considered in works [17,18].…”

The practice of benefication of copper-zinc ores has established that the production of high-quality zinc concentrates is impossible without the addition of sphalerite and pyrite modifiers to various flotation operations. This article present the result of study of the effect of copper (II), zinc and iron (II) sulfate on the froth flotation of sphalerite by sulfhdryl collectors. Typically, it is achieved through optimisation of flotation circuits, installation of modern equipment and changing the flotation reagents modes. Therefore, the floatability of sphalerite in an alkaline lime medium was studied with the addition of one of these metal sulphates to the mineral flotation operation. The effect of each of copper (II), zinc and iron (II) sulphates on the floatability of sphalerite was studied by flotation of the mineral and by potassium butyl xanthate and sodium dibutyl dithiophosphate at pH = 8, 10 and 12.

“…Steel fibres [1,2], PET [3], waste basalt rebars [4][5] and even rubber from used tyres [6,7] may be used to improve selected characteristics of composite materials in building and civil engineering. Potential reuse of CDW (construction demolition waste) is one of the leading areas of sustainable development [8] in construction and mining industry [9]. Reuse of spoil material and by-products Semm to be extremly attractive idea for mining industry that produces a lot of waste and needs large amounts of backfill material for safe mining production [10][11][12].…”

This article presents the issues related to using by-products and waste materials in constructionand mining industry. The current applications of selected materials in various areas are presented, with particularfocus on cases in the construction and mining industries, where waste-based composites sealed with various hydraulic binders are used to build new structural elements or just as fills and backfills. In the next part of the revivew, the methodology and selected results of shrinkage tests on concrete composite samples with the addition of various amounts of additives and price tests to reference samples without dispersed reinforcement are presented and discussed. Research has been carried out on the subject of balance between concrete and the semi-finished product used.
