Abstract

The urgency of the safety of the components of the natural environment of Central Kazakhstan is due, firstly, to the long development of solid minerals and, in connection with this, the huge expenditure of energy and water resources, and secondly, to the use of obsolete mining technologies. The complex of works on the extraction of solid minerals leads to a change in the entire range of environmental conditions in the mining areas and adjacent areas, which is due to the interconnectedness of all natural components among themselves. The article deals with the processes, associated with work in the mining industry, the beginning of which was laid in the first half of the ХХ century. A prolonged mechanical intervention in the surface, subsurface structures of the earth‘s crust led to the development of a number of dangerous geodynamic processes, that directly and indirectly degrade the ecological state of the surrounding area.

Geomorphological Risks and Assessment of Ecological-Geomorphological Situations of Mining Regions of Arid Zone of Kazakhstan

“…Modern geomorphological processes in the areas of active mining development lead to a noticeable redistribution of rock masses and corresponding changes in the structure of the earth's surface (landslides, landslides, karst and seismic-technogenic dips, soil heaving and sedimentation, active water and salt erosion, wind erosion and accumulation, etc.) (Cheskidov et al, 2018;Kassymkanova et al, 2018;Bexeitova et al, 2018). As a result of these and other processes, a crisis geomorphological situation may arise -in other words, a geomorphological risk of a certain degree.…”

“…The long-term resource-oriented orientation of the main economic sector of the region has led to the formation of a number of environmental problems, including geomorphological ones, characterized by stability due to their permanence and the increase in mining. Mining production in the study area, which requires large volumes of water, adequate infrastructure and is characterized by significant ground and underground mine workings and waste mass, has led to an imbalance of the regional geosystem -large changes in the geological and geomorphological environment and the formation of dynamic geomorphological risks, respectively, a sharp increase in load on all other natural ingredients (Bexeitova et al, 2018). The latter have low resistance to anthropogenic impacts and a high degree of accumulation of pollution, contributing to a significant deterioration of the ecological situation of the entire region.…”

“…The objective of this study was to study the problem of the formation of dangerous geomorphological situations and associated geomorphological risks within the platform-denudation plains of the arid zone of Kazakhstan, the territory of which is rich in mineral resources and has been actively developed since the 30s of the XXth century. The main sources of deterioration of the geological and Kaiser et al, 2014;Voskresensky et al, 2018;Cheskidov et al, 2018;Kassymkanova et al, 2018;R. Bexeitova et al, 2018) many others.…”

Selecting the rational parameters for restoring filtration characteristics of ores during borehole mining of uranium depositst

“…For example, in the United States alone, growth of 50% is pre-dicted by 2030. According to the Ministry of Energy of the Republic of Kazakhstan, global electricity consumption will double by 2030 [4], [5].…”

Use of Magnetic Fields for Intensification of Coal Gasification Process

“…The bulk of coal mined today has an increased ash content and contains a number of harmful impurities. Harmful impurities create unfavorable conditions for the use of minerals or have a harmful effect on the environment, including living organisms (Pavlychenko and Kovalenko, 2013;Lewińska andDyczko, 2016 Buzy lo et al, 2018;Bexeitova et al, 2018). A significant part of the coal reserves belongs to the off-balance category, which excludes their economically feasible mining using traditional technologies .…”
