Impact Of Mining

The purpose of the study is to influence land resources during mining operations, and the main stages of land reclamation during mining on the example of the Tyradinsky gold Deposit, the "Zolotaya Tyrada" quarry, located in the Yenisei region of the Krasnoyarsk territory. The main factors of impact on land resources in the process of mining the field are considered; the analysis of measures to reduce the negative impact on land resources in the process of mining the field is carried out. The actual height and area of overburden dump not to exceed project, the reconfiguration of dumps allowed us to reduce the impact of mining on the environment, to avoid placing parts of the dumps in the water protection zone of the river Terada, thus there is no need of land allocation to forests of the first group and reduced the amount of removed topsoil. During the reclamation, potentially fertile soils (loam) taken from the quarry were used. There will be no deterioration in the impact on land resources during the liquidation process, due to the short duration of the work and within the existing land allotment.

Mining and sustainable development may be compatible with the priority of measures to reduce impacts on the major ecosystems with severe consequences for the future generations. Infiltration of contaminated water into soils/rocks due to activity of different sectors of mining industry causes increasing concentration of minor and major deleterious elements in natural environment, forcing an economic operator to implement the best available techniques to solve severe environmental problems. The research is aimed at determining heavy metal contents in tailings storage facilities of coal mining operations in the eastern part of JiuValley, revealing mechanism of interaction of the TSF infiltrate with EastJiuRiver, as well as assessing the impact of the TSF on quality of the natural environment. One more aim of the research was to determine the ways by which the TSF components produce negative impact on the soils and surface waters. The obtained results can be fundamental basis for the future researches in the field of closing and maintaining the mining activities in JiuValleyand the land reclamation.

Water Assessment

The primary objective of the water protection in the Water Framework Directive No. 2000/60/ EC is to maintain and improve the water environment by achieving good water status. These provisions have been implemented into Polish legislation in the Water Law Act of 2017. These goals are achieved by the use of appropriate legal instruments as a system of water-law approvals, including a permit, notification and legal-water assessment. The subject of the analysis is water-legal assessments as a new legal and administrative instrument of water protection. The aim is to deter-mine the legal nature of water-law assessments and to indicate their role in the protection of surface waters. Obtaining this assessment is required for investments that may affect the possibility of achieving environmental goals. If the planned investment has a positive or no impact on the possibility of achieving the environmental goals, it seems that the legal-water assessment is made. In the case of a negative impact, the obligation to submit documents confirming that all measures are taken to mitigate the negative effects of the impact on the state of water bodies are imposed. In this way, the legislator strengthened the protection of waters by imposing the obligation to meet additional conditions for large-scale investments that have a negative impact on the water environment.

Purpose. The aim of the work is to quantify the indicators of the environmental impact of mining enterprises on the state of the natural environment during the operation of a mining enterprise and after its liquidation. Method. The paper uses a computational and analytical research method. Results. Based on the calculations performed, it was established that the specific assessment of the environmental impact on the biosphere components of the Mining Enterprise PJSC "MM "Pokrovskoe" for the entire estimated period of the mine's existence: lithosphere – 0.071; hydrosphere – 0.02; atmosphere – 0.77; biota – 0.009; physical fields – 0.13. After the liquidation of the mine, due to the termination of coal mining operations from methane-free coal seams, the absence of emergency gas emissions, as well as a decrease in noise and heat pollution, the specific impact on the atmosphere (0) and physical fields (0.0004) is significantly reduced, but at the same time, the impact on the hydrosphere (0.26) and lithosphere (0.72) significantly increases, which is associated with changes in the hydrological regime of water and the deterioration of mine discharges of water quality in the hydrographic network due to pumping mine effluents to the daytime surface, with the dry method closing the mine, and waterlogging of the territory with a wet and combined method of closing the mine. The indicator of specific impact on the biota (0.009) does not change. Scientific novelty. A methodology for calculating indicators of the environmental impact of mining enterprises on the state of the natural environment is proposed. Practical significance. The obtained indicators of environmental impact on the components of the biosphere can serve as a basis for developing measures to reduce the negative manifestations of mining enterprises on the state of the natural environment. Key words environmental risk, mining enterprise, biosphere components, environmental impact.

Mining Plant

Environmental protection law and geological and mining law require the mineral mining plant to protect its surroundings from the effects of mining operations. This also applies to the negative impact of vibrations induced by blasting works on people and construction facilities. Effective protection is only possible if the level of this impact is known, therefore it is necessary to record it. The thesis formulated in this way has been and continues to be the guiding principle of the research works carried out in the AGH Laboratory of Blasting Work and Environmental Protection. As a result of these works are procedures for conducting preventive activities by open-pit mines in order to minimize the impact of blasting on facilities in the surrounding area. An important element of this activity is the monitoring of vibrations in constructions, which is a source of knowledge for excavation supervisors and engineers performing blasting works, thus contributing to raising the awareness of the responsible operation of the mining plant. Developed in the Laboratory of the Mine's Vibration Monitoring Station (KSMD), after several modernizations, it became a fully automated system for monitoring and recording the impact of blasting works on the surrounding environment. Currently, there are 30 measuring devices in 10 open-pit mines, and additional 8 devices are used to provide periodic measurement and recording services for the mines concerned.

Impact Of Mining

Nowadays, the functioning of mining companies is conditional not only on the market situation, but also on the good relations with stakeholders. Good relations with recipients, suppliers, employees as well as with local communities and environmental organisations are of crucial importance. Social acceptance is becoming one of the primary conditions for mining operations. The main complaint faced by mining companies is their negative impact on the environment. It is, therefore, important to determine not only the measures aimed at reducing the negative impact of mining on the environment, but also the amount of expenditures allocated for this purpose. The main aim of this study is to analyse the investment outlays allocated for environmental protection. In order to support the aim of the study, a statistical analysis of data from 2003-2016 was carried out in terms of the structure of outlays for environmental protection: air and climate protection, water and sewage management, and soil protection, as well as protection against noise and vibration.

Abstract This article concerns numerical modeling of the impact of mining operations on fault behavior, carried out on the basis of a calculation program based on the finite element method. The calculations and their graphic results related to the reactions of vertical discontinuity on the mining operations that run along its boundary under changing operating parameters, such as geometry of the field and direction of mining with respect to the fault, as well as the method of liquidation of the caving zone. The behavior of the fault was analyzed based on distributions in the plane of shear stress and slip, together with their range and energy dissipated due to friction. The results of numerical calculations made it possible to draw conclusions on the impact of faults and the impact of operating conditions of mining in their vicinity on the level of seismic hazard.

Research rationale. The current state of the natural environment in the northwestern part of Ukrainian Polissia is characterized by a huge-scale changes in cultivated lands. The reasons for the disturbance of the structure of natural landscapes are the unauthorized extraction of gemstones, in particular, amber. Problem statement. For Ukraine, this issue has become particularly acute as the environmental consequences of illegal mining are quite disastrous as far as the disturbed biotopes cannot be restored to their original state in a natural way without human intervention, thus they need to be recultivated. Analysis of recent studies and publications. The researches that cover the agenda include the issues of monitoring and determination of locations of lands disturbed due to illegal amber mining as well as the use and classification of lands disturbed as a result of mining industry’s activities. Uninvestigated parts of general matters defining. The introduction of an economic and legal mechanism for compensating by the violator for damage caused by illegal amber mining and the failure to carry out land reclamation after the completion of mining operations will ensure more effective protection of the interests of the state and territorial communities as well as the rights of owners and exploiters of land plots, and will have a positive impact on reducing breaches of law in the area of land utilization. Objective of the research. The purpose of the study is to assess the impact on the environmental condition of the Rivne oblast as well as economic assessment of the extent of damage caused by illegal gemstones mining. Statement of basic materials. Obvious signs of negative anthropogenic impact related to unauthorized use of subsurface resources have been established, namely: the unauthorized removal of the fertile soil layer, excitation of the entire structure of the soil cover, hydrological regime, geological structure of the subsoil area, destroyed vegetation. At the same time, disturbance of land, both for forest and agricultural purposes of various forms of ownership. Following the researches, the extent of damage and compensation to the state resulting from the illegal mining of gemstones was determined. Conclusions under the article. On the territory of the Ukrainian Polissa the technogenic sand massifs and badlands are being intensively formed, which area is constantly increasing. The spread of such formations on the lands of forestry and agricultural purposes creates a threatening ecological and economic situation throughout the region.

Small limestone quarries are located everywhere. After mining operations have been completed, they are not recultivated and left for self-growing. In order to assess the process of vegetation cover restoration, field studies were conducted at 6 quarries located in different climatic zones of Eastern Siberia and Abkhazia. A description of the quarries was made, and areas of disturbed land were identified. The impact of various factors on the self-growth was studied, including the mining parameters, the size of quarries, the height of ledges, the width of berms, the angles of slopes, the composition of rocks in the surface layer, the exposure of slopes, and the composition of surrounding plants. The research identified factors that have positive and negative effects on the intensity of self-growth; recommendations for forming non-working boards were provided. Mining operations without the implementation of reclamation measures aimed to create favorable conditions for the self-overgrowing of disturbed lands, impair the process of vegetation restoration and entail long-term erosion processes, despite the favorable conditions of the subtropical climate of Abkhazia. The available solutions for land reclamation in Siberian quarries can be implemented in other climatic zones.
