In central and western Poland in the rural areas there is a lot of lignite deposits, which utilization by building mining and power complexes could give impetus to development. The paper attempts to evaluate the impact of their construction by comparing socio-economic development indicators and quality of life conditions of residents in two regions. In the area of Belchatow, in which operates the largest lignite mine and the lignite fired power plant (commune Kleszczow) and commune around deposit Gubin-Brody with ...

Costs in mining and extractive enterprises is a critical factor for competitiveness. The reason is enormously expensive equipment and technology associated with this type of business. It is therefore necessary to identify the so-called critical cost type, not only in enterprise but also in the entire industry of the country. Slovak Republic, calculated on an area, belong to one of the world's mining superpowers and take leading positions in mining of selected types of raw materials [6]. Mineral resources are the b...

Mining rail transport is one of the main transport systems within intra-plant logistics of mining enterprises. Its main task is the transportation of raw materials from mining sites for further processing. For efficient operation it is necessary to apply planning and optimization tools. Within the optimization processes as a one of the key tools in engineering practice appears to be a computer simulation method. For proper applying it is, however, necessary to handle modelling of some particularities which are rel...

The area of interest (Slatinice wastedump) is located on the southern edge of the Most?s basin central part (North Bohemia, The Czech Republic). The wastedump was deposited into the space of the fomer lignite openpit mine, called Slatinice. The body of the wastedump has an ovoid shape with the longer axis oriented in the NW ? SE direction. The major thickness, about 100 m, reaching a dump in its central part. Monitoring wells have been realized in the area of interest between the years 2013 ? 2016. The aim of this...

The investigation of the fault tectonics in the Kovdor carbonatite intrusion (NW Russia) has resulted in the identification of a new brittle deformations type. It is formed due to the simultaneous turn of fissure planes at discrete angles around two orthogonal guiding lines (axes), where one is represented by a vertical massif symmetry axis (L1), and the other axis (L2) lies horizontally in the fracture plane. Nonetheless, the rotation along the both axes is codirectional, i.e., when moving counterclockwise around...

Mineral fuels are among the non-renewable natural resources. For this reason, would be addressed in a responsible and rational use. Mineral fuels are among the so called strategic raw materials, the use of which is essential to the national economy and energy security. Raw materials base in Slovakia as regards energy raw materials consists mainly of brown coal, lignite and uranium, part of the oil and natural gas. To determine the prospects for the use it is necessary to know the quantity of reserves and the econo...

Uranium mining is the first step in the nuclear fuel cycle to produce energy. In the nuclear fuel cycle, main steps are; Mining / Milling, Conversion, Enrichment, Nuclear Fuel Fabrication, Reactors, Reprocessing of the spent fuel and Waste Management. In the first step, there are three main methods for uranium ore extraction. These are; Open Pit Mining, Underground Mining and In-Situ leaching (ISL/Lixiviation). All forms of mining methods create health risks for people and hazard for the environment. In this study...

Working in mining companies, which extract coal, is very difficult and dangerous. Miners carry out activities in a hostile environmental in which there are many natural and technical dangers. The accumulation of such unfavorable factors makes it necessary to take actions to appropriately prepare the workers to work in these conditions. These actions mainly include different kinds of trainings before and during the work. One of the goals of these trainings is to make the workers get to know the threats that occur i...

The area of the CSA mine is situated at the northern edge in the central part of the Most Basin (North Bohemia, The Czech republic). The interesting area, currently represented by the internal wastedump and the own openpit mine CSA, has undergone significant changes over time that are associated almost with coal mining activities. This activity hit especially hydrological and hydrogeological conditions of the area. The original surface was naturally drained by the several streams, which were necessary translate to...

Mining generates a negative impact on the areas after stopping mining activities. Causing mines closed because of their specific, multiple and varied adverse effects on the environment by land degradation, by vertical and horizontal surface and sliding heaps and tailings ponds; polluted surface waters and groundwater; hydrodynamic imbalance of groundwater; negative influences on the atmosphere, flora and fauna; chemical pollution of the soil. Mining gold mine Barza - Brad is currently stopped, the mine was closed....

The effectiveness of enrichment process of run-of-mine copper ore (at KGHM?s ore enrichment plants) depends on the selection of appropriate working parameters of processing machines which are customized mainly to fit the fed rock type. Therefore, the knowledge of lithological composition of run-of-mine copper ore fed to the ore processing plant can significantly improve the effectiveness of the enrichment process. The issue of optimization of enrichment processes with the help of the use of in-situ sensor technolo...

The risk assessment of buildings in mining areas is being related to the adoption of appropriate measurement methods. These facilities should be properly analysed for the threat to mining activities. The surveys having conducted on the area subjected to continuous deformation caused by underground mining, allow to determine the impact of this exploitation on the buildings located on the soil surface. Surveys are often the only source of information on the impact of exploitation on local infrastructure. Surveys met...

The article aims at the presentation of results as well as the prognosis of deformations during mining works based on experimental measurements. For this study were explored the directional galleries from the layer nr.3 and transversal galleries from the mining basin in Valea Jiului. According to the depth of exploitation, the mining works are situated in rocks with variable resistance. In order to increase the reliability of mine works for the opening and afferent preparing of mining field from Valea Jiului, the ...

The mining companies are often faced with the requirement for bulky material transfer which is possible to realize using overhead travelling cranes. An overhead travelling crane has rectangular work space, which is characteristic for this type of crane. A part of an overhead travelling crane is also a crane crab. Crane crab movement is carried out after the double-girder crane construction and loads are displacing along the whole length of the crane. The aim of this paper is a proposal of 3D geometric model of the...

Following mining and processing activity, results a significant amount of mining wastes, in the form of sterile mineral. These wastes are stored largely in mining tailing ponds or heaps. The chemical composition of the sterile material depends from one mining site to another. For long time worldwide, tailing deposits were considered waste deposits, without the possibility of future use. A few of the negative effects on the environment my constructing and exploiting mining tailing ponds, heaps, landfills, are the d...

The purpose of this article is to describe the modern methods of making models of quarry using the latest technologies such as laser scanning, land and air photogrammetry using Unmanned Aerial Vehicles (UAV) and their subsequent use in the planning of technological processes in the quarry. The first part of the article is dedicated to the creation of models with a focus on data collection and processing, compatibility of each format, the very creation of the model as well as the possibility of using the created mo...

In late January of 2016 (27/01/2016) at Mining Section 14 (Block 7/10) of the Kukisvumchorr flank of the Kirovsk Mine (Khibiny), a violent seismo-dynamic event (lgE ? 8.11) took place to induce significant destructions and deformations of workings at Drill & haulage horizon 4 (4DHH) with an average elevation of +236 meter, 1DHH (+183 m), and possibly at 2DHH (+209 m), which is unavailable for examination. The dislocations, deformations and roof break formation occurred both at the cross-measure (predominantly) and...
