The topic presented in the paper refers to two significant aspects regarding the impact of mining operations on the environment and the development of an alluvial mining project in the affected area. The mine waters that drain from the Cizma mining perimeter have an acidic character with a pH of 2.5 at the exit of the gallery with a load of heavy metals in ionic and precipitated form, discharging into a mountain stream, which later reaches in the area of some communities. The perimeter is located in a protected area, which encumbers exploitation projects in these areas.

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.

Impact Of Mining

Land subsidence caused by groundwater withdrawal induced by mining is a relatively unknown phenomenon. This is primarily due to the small scale of such movements compared to the land subsidence caused by deposit extraction. Nonetheless, the environmental impact of drainage-related land subsidence remains underestimated. The research was carried out in the “Bogdanka” coal mine in Poland. First, the historical impact of mining on land subsidence and groundwater head changes was investigated. The outcomes of these studies were used to construct the influence method model. With field data, our model was successfully calibrated and validated. Finally, it was used for land subsidence estimation for 2030. As per the findings, the field of mining exploitation has the greatest land subsidence. In 2014, the maximum value of the phenomenon was 0.313 cm. However, this value will reach 0.364 m by 2030. The spatial extent of land subsidence caused by mining-induced drainage extends up to 20 km beyond the mining area’s boundaries. The presented model provided land subsidence patterns without the need for a complex numerical subsidence model. As a result, the method presented can be effectively used for land subsidence regulation plans considering the impact of mining on the aquifer system.

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.

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.

Abstract The industrial development of mankind is based on the intensive use of natural resources of the planet. The development of the mining industry is a necessary and important factor for the successful development of the national economy. At the same time, mining has a significant impact on environmental degradation. Methods for assessing and minimizing the environmental impact of mining have only been developed in practice in the last 50 years and differ significantly from country to country. The article analyses the approaches and methodologies for environmental impact assessment (EIA) based on international and national standards. The methods used in Kazakhstan and the countries of the European-Asian Economic Union (EurAsEU) are critically evaluated. The developed mathematical models are implemented in the form of digital solutions and implemented in the module of the cloud system ‘3D Quarry’. The methodology proposed by the authors for use and the developed software product allow optimizing mining operations at quarries according to the parameters of minimizing their negative impact on the environment. At the same time, it is mandatory to comply with mandatory national and international regulations. The proposed 3D Quarry system and the EIA module are an alternative to commercial software products (and their pirated copies, often used by companies in the countries under study) and are aimed at small mining companies in post-Soviet countries. It is expected that the application of the proposed software product will allow, within the technological capabilities, to minimize the impact of quarries on the environment of Kazakhstan.

Impact Of Mining

The impact of transition periods is experienced by the local population and economy as a result of mining activities closure and dismissal of a large number of workers followed by diversification of employment and career reorientation opportunities. The aim of the paper is to highlight the impact generated by closure of mining operations on local society and economy as well as identifying opportunities for harmonious development of communities in the Jiu Valley. Following the assessment of the social impact of mining activities closure, we found a rising tendency of unemployment rate among the middle-aged population that did not benefit from vocational retraining and the growing tendency of young people to leave the region for strictly economic reasons leading to widespread social aging.

The Impact

Insufficient funding for terrestrial protected areas is a global challenge, and the ability of a protected area management agency to secure sustainable financing is an obstacle in the effective management of these important areas. While the role of public sector agencies in establishing, financing, and managing protected areas, and in providing a supportive legislative and policy environment will remain essential into the future; the International Union for the Conservation of Nature (IUCN) recommends that alternative finance mechanisms be adopted to help achieve financial sustainability. With this recommendation in mind, one approach is to look to other policy areas which traditionally rely on governments as their primary funding source, to understand the alternative finance mechanisms they have adopted and appraise the suitability of these mechanisms for terrestrial protected areas. One alternative finance mechanism is the social and environmental impact bond which is a subset of impact investment and an example of a pay for success or results-based contract. This paper reviews literature on the social and environmental impact bond with a view to assessing its potential applicability to assist in the effective management of terrestrial protected areas that fall within the management categories defined by the IUCN. Three examples of existing and proposed impact bonds with an environment focus are explored, including the world’s first environmental impact bond in Washington D.C., the publicly offered Atlanta environmental impact bond and the proposed wildlife conservation bond in South Africa. The selected impact bonds will help to illustrate the establishment, operation, and evaluation of impact bonds in a real-world context. It will be argued that the social and environmental impact bond can be a useful finance model for a range of uses in a variety of social sectors and conservation settings, including terrestrial protected areas. The paper further considers how the impact bond might result in both improved social and/or environmental outcomes as well as the perceived challenges associated with this alternative finance mechanism. While the focus of this paper is on terrestrial protected areas, the lessons discussed may also be applicable to marine protected areas.
