Abstract Analysing environmental impacts of mining activities involves detailed studies of the interactions between technological activities/operations carried out in a mining operation and environmental components affected by them. In order to carry out a more complex environmental impact assessment caused by mining in the eastern part of Jiu Valley on soil and water 4 mining units have been considered in the study, these being mining unit Lonea, Petrila, and Livezeni with their belonging dumps. Main objective of this research is to analyse the impact caused by mining activities in Eastern part of Jiu Valley by the method of impact networks according to the model “causes - pressures, depreciation of the quality of environmental factors – affected parameters - impact”. Thus, impacts caused by the mining industry were identified based on the top-down typology, being shaped impact networks for underground coal exploitation and sterile material storage on the surface. The metal content of the dumps was also analysed in order to assess the degree of metals soil enrichment compared to the reference concentration of a blank sample. The analysis of the influence of the local rainfall regime aims to highlight the leaching potential of heavy metals in the body of the dump and the possibility of analysing the scenarios of extension of the pollution phenomenon to the saturated area. The study is addressed to researchers, environmental engineers, hydrogeologists and geologists who want to deepen the study of transfer mechanisms of contaminants from dumps to watercourses receiving areas and their dispersion in unsaturated and saturated areas.

Abstract This paper presents aspects related to water pollution with heavy metals from the Tarnita mining area before and after the cessation of the mining activity. The impact of heavy metals on waters is important because these metals have a negative impact on both human health and aquatic ecosystems. All research data showed that, even the mining activities from this area were suspended, the sterile still pollutes the soil and water

Nuisance for the people living in areas covered by the direct or indirect impact of the mining industry is an important social problem. The development of the mining industry depends on high environmental requirements, in particular, it is closely related to the fulfillment of obligations of safety for human health and life. Through consultation with the local society and targeted actions degraded land can become attractive. In contrast, the lack of reclamation leads to the intensification of negative phenomena: erosion, surface mass movements, changes in the ecosystem, eutrophication of water tanks. Maintaining balance in the natural environment is the basic criterion for the proper functioning of industrial facilities. Mining activity is a threat to the environment, including human health and life. Use of the environment by mining is subject to adjustment to the legislation and carrying out mining activities in line with environmental requirements. Mining activities and nature protection can operate in a sustainable manner. Appropriate selection of methods for mineral exploitation allows you to minimize the impact on the environment components. The positive impact of opencast mining is reflected in the creation of new habitats of plants and animals in post-mining areas, in the creation of new recreation places, in diversifying the landscape thanks to the construction of water reservoirs. Lakes formed after use of natural aggregates overgrown vegetation reed, acting as a convenient place to settle the water birds.

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.

The development of the mining industry is necessary for the national GDP growth. The gold mining operation provides great support to local people in the construction of roads, hospitals and schools. However the damage caused due to the illegal gold mining in Ivory Coast has become increasingly worrying. Thousands of miners unlawfully exploit gold in many parts of the national territory. The local people, especially the children see artisanal gold mining as a faster way to get out of the growing poverty. According to the investigation with local people, MDA, mining companies, the rebellion in 2002 and the post-election crisis in 2010 were a key issue. As result of the political unrest many children have left school to move into the mining activities. This paper focuses on some existing problems relating to the minors in artisanal gold mine as well as how the illegal gold mining activities should increasingly concern the state’s authorities who have to display their determination to stop this recurring phenomenon. In this paper, some suggestions will be proposed and we also support some initiatives and actions of the current government in order to reduce the rate of children or if possible to withdraw all the children from mining sites. The World Bank, financial institutions, NGOs are appealing too to play a major support role to eradicate child labor and to protect children in Ivory Coast and over the world.

The mining industry plays an important role in the economic development of Malaysia. However, uncontrolled mining activities have caused serious environmental impacts. Recently, bauxite mining in Kuantan, in the state of Pahang, stained fifteen kilometers of Pahang’s coastline with red arsenic particles and heavy metal pollution washed from open-pit bauxite mines into the nearby sea. This has caused potentially catastrophic damages to the ecosystem off the coast of Pahang. This triggered the Government of Malaysia to issue a temporary ban on bauxite mining while the state government engaged in expensive clean-up. Mining activities require an Environmental Impact Assessment (EIA). Environmental decisions are complex and multidisciplinary including knowledge bases which incorporate natural, physical, and social sciences, politics, and ethics. This research proposes a decision support framework that uses the Analytic Network Process (ANP) to help decision makers in EIA pertaining to the bauxite mining industry.

Mining practices in Cameroon began since the colonial period. The artisanal mining sector before independence contributed to 11–20 % of GDP. From 2000, the rich potential of the Cameroonian subsoil attract many foreign investors with over 600 research and mining permits already granted during the last decade. But, Cameroonian forests also have a long history from the colonial period to the pre-sent. However, mining activities in forest environments are governed by two different legal frameworks, including mining code i.e. Law No. 001 of 16 April 2001 organizing the mining industry and Law No. 94-01 of 20 January 1994 governing forests, wildlife and fisheries. Therefore, in the absence of detailed studies of these laws, there are conflicts of interests, rights and obligations that overlap, requiring research needs and taking appropriate decisions. The objective of this research in the Lom and Djérem division is to study, apart from the proliferation of mining li-censes and actors, the dilemma as well as the impact of the extension of mining activities on the degradation of forest cover. Using geospatial tools through multi-temporal and multisensor satellite images (Landsat from 1976 to 2015, IKONOS, GEOEYE, Google Earth) coupled with field investigations; we mapped the dynamic of different forms of land use (mining permits, FMU and protected areas of permanent forest estate) and highlighted paradoxically the conflict of land use. We came to the conclusion that the rhythm of issuing mining permits and authorizations in this forestall zone is so fast that one can wonder whether we still find a patch of forest within 50 years.

AbstractAny human activity causes environmental degradation, resulting in a continu ous deterioration of environmental quality (water, air or soil). While mining is also an activity that causes degradation of the environment, it is essential for the continuity of life as it is known. On the other hand, paradoxically, by keeping life in this way, we are contributing to its cessation. This leads us to look for alternatives to reduce the impact of mining activities. The Reclamation of degraded areas may be an alternative, as it can mitigate the current picture of continuous environmental degradation.However, Degraded Areas not always follow a mining operation. This article presents a case where mining is the tool used to technically and financially allow the Reclamation of a degraded area.

Municipal solid waste (MSW) landfills and tailings storage facilities of mining enterprises often operate in similar hydrogeological conditions and have similar requirements for their design, operation, and closure. Therefore, the examination data set obtained for MSW landfills may also be used when assessing the environmental impact of waste disposal facilities in the mining industry. The body of data collected for such landfills contains certain information that is rarely studied for tailings storage facilities of mining and processing enterprises. These include the influence of hydrological conditions on the processes occurring within the landfill, regularities of sediment infiltration and leaching, the composition of the filtrate released, migration of pollutants outside the waste disposal facility, and formation and monitoring of gas emissions. Thermal recycling and composting were selected as the MSW handling technologies studies. The data on the joint disposal of MSW and related incineration ash, MSW-based compost and the municipal solid waste itself are presented. Studies on the consequences of joint waste disposal for the environmental impact of landfills are analyzed. The above analysis established that extraction of recyclable components from MSW for reuse or energy use would reduce the volume of MSW entering the disposal sites; biological or thermal treatment of MSW for the purpose of neutralization and volume reduction would reduce both the volume of MSW entering the disposal sites and the related biological hazard; and combined disposal of MSW with products of biological or thermal decontamination of MSW would lower the biological hazard of disposal. The study was carried out under the grant issued by the Russian Science Foundation (project No. 19-79-10114).

The purpose of this study is to examine the impact of Shariah governance and corporate governance (CG) on the risk management practices (RMPs) of local Islamic banks and foreign Islamic banks operating in Malaysia. The Shariah governance comprises the Shariah review (SR) and Shariah audit (SA) variables. The study also evaluates the level of RMPs, CG, SR, and SA between these two type of banks. With the aid of SPSS version 20, the items for RMPs, CG, SR, and SA were subjected to principal component analysis (PCA). From the PCA, one component or factor was extracted each for the CG, SR, and RMPs while another two factors were extracted for the SA. Primary data was collected using a self-administered survey questionnaire. The questionnaire covers four aspects ; CG, SR, SA, and RMPs. The data received from the 300 usable questionnaires were subjected to correlation and regression analyses as well as an independent t-test. The result of correlation analysis shows that all the four variables have large positive correlations with each other indicating a strong and significant relationship between them. From the regression analysis undertaken, CG, SR, and SA together explained 52.3 percent of the RMPs and CG emerged as the most influential variable that impacts the RMPs. The independent t-test carried out shows that there were significant differences in the CG and SA between the local and foreign Islamic banks. However, there were no significant differences between the two types of the bank in relation to SR and RMPs. The study has contributed to the body of knowledge and is beneficial to academicians, industry players, regulators, and other stakeholders.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.
