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.

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.

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.

This research article presents a software module for the environmental impact assessment (EIA) of open pit mines. The EIA software module has been developed based on the comprehensive examination of both country-specific (namely, Kazakhstan) and current international regulatory frameworks, legislation and EIA methodologies. EIA frameworks and methods have been critically evaluated, and mathematical models have been developed and implemented in the GIS software module ‘3D Quarry’. The proposed methodology and software module allows for optimised EIA calculations of open pit mines, aiming to minimise the negative impacts on the environment. The study presents an original methodology laid out as a basis for a software module for environmental impact assessment on atmosphere, water basins, soil and subsoil, tailored to the context of mining operations in Kazakhstan. The proposed software module offers an alternative to commercial off-the-shelf software packages currently used in the mining industry and is suitable for small mining operators in post-Soviet countries. It is anticipated that applications of the proposed software module will enable the transition to sustainable development in the Kazakh mining industry.

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.
