Environmental issues at mining comp anies are so numerous, complex, and interconnected that an ad hoc approach to problem solving is no longer considered effective. The growing pressure from all st akeholders forces these companies to adopt environmental responsibility in all activities. There has a paradigm shift in the attitude of the companies as it switches over from “Passive environmental strategies“ to “Proactive environmental strategies”. In this paper, Integrated Eco Permissions (IEP), incorporated into th...

In Poland the closed shafts were filled up in the past years with th e rock material with very different backgrounds and properties. The effect of flooding the shallow, old mining areas, as well as the impact of water infiltrating from the surface, are observed on the surface as subsidence funnel and discontinuous crack. Using the geophysical surveys, numerical modeling, geologic al and hydrogeologi cal studied, some possibilities for diagnosis of hazards in abandoned coal mines areas are shown. In the context of ...

Within the lignite deposits located in the Oltenia coal basin, frequent sand bands are emerging, carriers of signifi cant aquiferous horizons and complexes. The geological pattern induces an important variation of hydro-geological conditions along the deposit’s spreading, which in turn gives difficulties in mining technology selection. Determining the problem’s solution involves th e versions ranking from the strongest to the weakest, in relation to all the criteri a. Both maximum and minimum criteria can exist. I...

Wind erosion of soil from exposed areas in mining sites is one of the sources for dust generation. Particle size distribution a nd mineralogical composition of source soil, erodible fraction of surface soil, moisture, as well as organic matter content are important factors that determine the property of particulate generation process. In this research four soil samples were taken using shovel at different depth from the edge of the pit and the surface area nearby the pit in Malmberget mine in Sweden. Soil samples ...

The aim of this paper is to show the possi bilities, how effective use GIS for modelling of mineral deposits, for example of brown coal deposit Nováky. The work results - seam base model and seam thickness model, ash content and heat value of coal presented in the ArcGIS are an example of a modern appr oach to the processing of geological data. The form of presentation offered by GIS allows much more efficient deposit data processing and provides greater op portunities for planning and optimization mining activiti...

Praid salt deposit is one of the largest in Europe: the salt body has an elliptic shape, with diameters of 1.2 km and 1.4 km, the depth being extended until 2,700 m. The mining methods employed in time are various: be ll-shaped rooms, trapezoidal rooms. Nowadays, the small rooms and square pillars is employed, the method being described in the paper. At 120 m depth, the cure and treatment facility is located. The underground atmosphere is highly ionized and very eff ective in treating respiratory diseases. The Pra...
