Abstract Mining is always connected with interference in the environment, especially with the landscape, hydrosphere and atmosphere. The increasing requirements of environmental standards in Europe influence actions taken by the mining industry, which leads to minimization of impact during exploration, exploitation, processing and use of raw materials and waste. Moreover, mining companies often compensate the environment transformations via the processes of reclamation and adequately chosen directions of further adaptation. New post-mining areas are characterized, in many cases, by higher values than before the commencement of mining works. The problem is still the depletion of non-renewable raw materials. This can be minimized by rational resource management and also by the effective use, recovery, recycling and substituting of minerals. These actions will have an impact not only on the extension of the operation of existing plants, but will also diminish the areas needed for extraction of new deposits. In the paper, the transformations taking place in the mining industry in Poland, as well as myths and threats connected with its further development were pointed out. The actions by this industrial branch which lead to minimization of the pressure on the environment and the applied reclamation were also shown.

The Cost

Further development of the open mining works on the domestic enterprises will be accompanied by the worsening of mining-geological conditions and declining of the quality of iron ore raw materials. In the same time, the accumulated mining wastes, that can make the technogenic deposits, pass into one of the important sources of the mineral raw materials. Taking into account this thing, the development and implementation of the modern technological circuits of the technogenic deposit development is an actual calling for mining industry, and determination and optimization of process conditions of the technogenic deposit development – is the scientific task of this publication. The obtained results of studies of the optimum step value of the ore chute transfer during the technogenic deposit development can be used by design organizations and mining enterprises for designing works. The obtained methodology and the proposed mathematical dependencies will reduce the cost of mining of the technogenic deposit due to the reasonable timely transfer of the open ore chute.

Further Development

At present, the acute question of rational resource consumption and resource saving arises in the republic. Sustainable development of the economy of Kazakhstan should be based on the planned and effective use of natural resources, in terms of the combined use of raw materials by enterprises of the mineral and raw materials complex. The current situation at the enterprises of the mineral and raw materials complex testifies to the need for the further development of the enterprise management system in order to obtain an additional chain of surplus value by passing out valuable components from raw materials. In connection, fundamental scientific research is needed, which makes it possible to scientifically substantiate improvement of the enterprise management system, the results of which can significantly improve the efficiency of the enterprise in the rational use of raw materials, both in terms of its processing, and in the direction of preserving the ecology of the region.

The Impact

The article is devoted to the issue of the possibility of economic development of the mining industry in the subjects of the Far Eastern Federal District (FEFD) and the impact of investment projects. With the vast wealth and diversity of mineral resources, their involvement in the national economy is an essential factor in the industrialization and successful development of the regions. In the case of the establishment of processing plants, for a number of minerals, the region could provide its own needs, as well as the countries, finished products from it, and develop an export focus. The article considers the export orientation of the mineral and raw materials complex of Russia and the constituent entities of the Russian Federation, as well as the commodity structure of exports of the regions of the FEFD. Special attention is paid to the implementation of major regional investment projects, which are important for the development of the regions. So, it is proposed to implement a major project in the form of an integrated mining and metallurgical complex due to the fact that the region needs its own ferrous metallurgy. The calculations carried out (in various versions: basic, in the conditions of the territory of advanced development (TAD), without the costs of infrastructure creation) showed that the implementation of the project is cost-effective, but due to the high costs, the support of the state is necessary.

The Impact

The level of development has been considered, the impact of mining industry on the world economy and its connections with other spheres of the world economy have been analyzed. Today mining industry is not only one of the leading fields of global economy, but it has also promoted the emergence of other fundamental branches. The development of this sphere is extremely important not only for the state, which plays the role of a regulator, but also for investors, contractors, suppliers, service companies, indigenous population and consumers. Due to its long-term development, mining industry differs from the majority of other kinds of human activity. Diversified mining industry is generally a prerogative of highly developed countries since only several segments are often functioning in less developed countries, and sometimes mineral raw materials are only extracted there. Nowadays no country in the world possesses full range of all types of rocks and minerals. Basic tendencies in development of extraction of mineral raw materials in different countries have been described. The current state of global mining industry can be called the advent of the so-called new era due to the increase of cost of mineral raw materials; however it is also necessary to develop the fields even with quite small and low-quality mineral reserves. Mining operations and development of mineral deposits are being relocated from the developed countries to the developing ones. It is better to consider the possibility of improvement of already existing objects instead of building brand new ones for more efficient and easier operation of mining companies. Problems of functioning and obstacles of development of mining enterprises in Ukraine under current conditions have been determined, ways of their elimination and increase of effectiveness in the branch in general have been proposed. National mining industry is adversely affected by such external factors as the global financial and economic crisis, processes of globalization. Although the mineral-raw material base of Ukraine has a sufficient amount of explored reserves of most mineral resources, it is currently at the stage of depletion of the subsoil, which requires the reformation of the economic mechanism for its use.

Introduction. In the industrial regions of Ukraine, the structure of nature formed over a long period without objective laws of development and recovery of natural resource systems and ecosystems. All natural ecosystems (atmosphere, hydrosphere, lithosphere and biosphere) have undergone forceful anthropogenic pressure. Chemical, radioactive and other pollution of the natural environment causes various, often incurable diseases, irreversible changes in the genetic structure of cells, which leads to an increase in the birth rate of defective generations. A special place in this context takes ecological safety in mining complexes. Mining complexes interrelated processes of human impact on the environment to provide raw materials and energy resources of various fields of economic activity. In a broad sense, the resource means as sources of matter and space - the environment of their location and life.Purpose. The purpose of the work is to highlight the importance of environmental safety management in mining complexes and areas for improvement.Methods. We used the methods of theoretical research to improve environmental safety in the mining complexes.Results. Based on theoretical research and improving environmental safety in mining complexes, the following measures are needed: control over the environment, reproduction and protection of its resources, improvement of natural living conditions, improvement of mining complexes as an environmental safety management system.Following environmental principles, it is necessary to manage the environment safety of mining complexes with the involvement of existing tools and methods of environmental analysis, as environment safety of this activity is of great importance for all areas of the environment. It is a question of studying of the zones of technogenic influence which are forming around dumps of mine breeds, and maintenance of physical, chemical stability of mining wastes. Management of ecological safety in mining areas will allow excluding the occurrence of the ecological-extreme situation after completion of the operation of coal deposits and during the future use of the disturbing territories. Stimulating self-education and ecological education, practical activity is at the same time a kind of generator in the process of developing beliefs in the main direction of the knowledge of conscious and responsible attitude to nature, ecological consciousness.Conclusion. Reasonable measures must regulate the impact of mining complexes on the environment. That means the monitoring of the state of the environment in mining areas; assessment of the threat of environmental hazards; prevention of complication of the ecological situation of the mining area (reclamation, phytomeliorative measures of heaps); development (implementation) of appropriate programs aimed at reducing environmental hazards.

Northwest Iberia

Northwest Iberia can be considered as one of the main areas where tin was exploited in antiquity. However, the location of ancient tin mining and metallurgy, their date and the intensity of tin production are still largely uncertain. The scale of mining activity and its socio-economical context have not been truly assessed, nor its evolution over time. With the present study, we intend to present an integrated, multiscale, multisensor and interdisciplinary methodology to tackle this problem. The integration of airborne LiDAR and historic aerial imagery has enabled us to identify and map ancient tin mining remains on the Tinto valley (Viana do Castelo, northern Portugal). The combination with historic mining documentation and literature review allowed us to confirm the impact of modern mining and define the best-preserved ancient mining areas for further archaeological research. After data processing and mapping, subsequent ground-truthing involved field survey and geological sampling that confirmed cassiterite exploitation as the key feature of the mining works. This non-invasive approach is of importance for informing future research and management of these landscapes.
