In this article an attempt was made to analyse the Bytom city relief changes in 1883-1994 years. It concentrates on the forms which are an effect of the mining and metallurgical activity such as subsidence depressions and dumps. Two digital relief models representing a topographic situation in year 1883 and 1994 were made by the Vertical Mapper tool in order to determine changes in the relief. The models were made by linear vectorization of contour lines, which then were processed into points. The made points were interpolated by the natural neighbour method. Maps of slopes, area profiles, contour line sketches and hypsographic curves were generated for two time periods on basis of the digital relief models. An area and values of subsidence for areas subjected to the mining activity, changes of the slopes, an average land altitude in 1883 and 1994 year were determined and an anthropogenic denudation ratio was also calculated. As the result of the research made, it has been established that the area of the subsidence is 3727 ha (about 54% of the city area) and the maximum value of subsidence is about 37 meters, there was a growth of the slopes at a simultaneous drop of the land average altitude, and the anthropogenic denudation ratio is 44 mm/year (800 greater than the natural denudation ratio).

Landscape may be described as a part of space characterized by a certain physiognomy, which is a dynamic system subject to evolution. An important factor influencing the type and condition of the landscape is human activity which shapes or rebuilds its structure. Interesting results may be obtained on comparison of archival cartographic materials with contemporary studies and zoning plans. The Upper Silesian Coal Basin is a region with a clearly transformed landscape. The determinant of the geographical environment transformation here is the anthropogenic factor. The study area includes the upper part of the Kłodnica catchment (229.6 sq km). The study is a review, and its aim is to systematize data sources used in the research on the transformation of landscape structure of a heavily industrialized area. In the first half of the nineteenth century created the "Urmesstischblätter" in the scale of 1:25 000. Afterwards preparations began to take new topographic images of the country (the "Messtischblätter"). In the 1990s initiated the development of a new topographic map (in the scale of 1:10 000). Recent data source is for example the project CORINE Land Cover 2006. There are many of various sources of data on land cover. An important aspect is the proper selection of documents and maps, and their proper interpretation.

The article deals with the issue of the release of methane from coal seams and its emission to the atmosphere from the mines of Katowice Coal Holding Company in the years of 1997-2011. This period is characterized by organizational changes in Polish mining industry involving liquidation or a merger of mines, an increase in both the concentration of coal mining activity, and the depth of the exploitation at which the amount of methane in coal seams grows ever larger. The analysis of the variation in the methane emission from the coal mines in that period points out a decline in the intensity of the emission until 2005, probably owing to the liquidation of some mines, later, but in the years of 2006-2010 - a considerable increase in both the absolute methane emission of the mines and the methane emission to the atmosphere despite a dropping coal extraction. This signifies that mining activity takes place in increasingly difficult gas conditions prevailing at great depths. Despite a slight decrease in both the absolute methane emission and methane emission to the atmosphere in 2011, a continuously growing trend of this phenomenon should be expected in the future. A similar tendency is also visible in the whole Upper Silesian Coal Basin, however the methane emission peak falls in 2008. In order to curb the growth of the amount of the emitted methane, it should be commercially utilized. Particularly vital is considering methane as an unconventional resource, following the example of other countries.

W polskim przemyśle górniczym powstaje średnio ok. 35 ∙ 106 Mg odpadów rocznie. Zwałowiska pogórnicze po eksploatacji węgla kamiennego w Polsce zlokalizowane są w obrębie ponad 250 obiektów, w trzech zagłębiach węglowych: górnośląskim (GZW), dolnośląskim (DZW) i lubelskim (LZW). Z występowaniem zwałowisk pogórniczych wiąże się wiele zagrożeń dla środowiska naturalnego, a także dla mieszkańców terenów z nimi sąsiadujących, co wymaga podjęcia skutecznych środków zapobiegawczych. W artykule, na bazie przeprowadzonych badań terenowych, przedstawiono rozmieszczenie oraz charakterystykę zwałowisk pogórniczych na obszarze Górnośląskiego Zagłębia Węglowego. Omówiono najważniejsze aspekty środowiskowe dotyczące składowania odpadów górniczych. Dokonano oceny technicznych możliwości odzysku węgla ze zwałowisk jako antropogenicznych złóż wtórnych, uzupełnionej ekonomicznym uzasadnieniem odzysku węgla ze zwałowiska pogórniczego. Przedstawiono także uregulowania prawne związane z eksploatacją tych obiektów.

Polish coal mining industry produces ca. 35 millions Mg of mining wastes per year. There are ca. 250 post – mining dumping grounds in Poland, situated in three coal basins: Upper Silesian Coal Basin, Lower Silesian Coal Basin and Lublin Coal Basin. Post – mining dumping grounds may cause serious environmental hazards. Their negative influence on the natural environment, as well as risks posed to the inhabitants, calls for effective preventative measures. In the paper, presented are distribution and characteristics of post - mining dumping grounds in the Upper Silesian Coal Basin. The most important environmental issues connected with disposing of wastes are discussed. Technical possibilities of recovery of coal from waste dumps as anthropogenic secondary deposits are analyzed. An example of economical justification of recovery of coal from post – mining dumping ground is presented. Also mentioned are legal regulations connected with exploitation of waste dumps.

The traditions of coal mining in Upper Silesia date back to 16th century, with the first mentions about coal extraction in the neighbourhood of Ruda Śląska, Katowice and Mikołów. Strong development of mining through centuries was not only the source of economic gains, but also the cause of significant changes in the natural environment of the region. Such changes are mainly various types of damage, e.g. subsidence, water salinity, rock mass disruptions, as well as changes resulting from the technological process – i.e. post-mining dumping grounds. The aim of this article is to assess the impact of the deposition of mining waste and its effects on the terrain of Mikołów poviat and show the changes of the structure of extractive industry in the local scale. The subject field consists of defining the localisation and geological structure of the study area, expressions of degradation of the terrain caused by mining activity, assessment of the impact of mining waste tipping on the terrain and natural environment and evaluation of the reclamation state of degraded areas. As a result of the research, a geomorphological profile has been made. The changes of the structure of extractive industry in the local scale is exemplified on the case study of recovery of coal from one dump in the northern part of Mikołów poviat.

Tradycje górnictwa węglowego na Górnym Śląsku datują się na XVI wiek, z którego pochodzą pierwsze wzmianki o wydobyciu węgla kamiennego w sąsiedztwie Rudy Śląskiej, Katowic i Mikołowa. Intensywny rozwój górnictwa w poprzednich wiekach był nie tylko źródłem zysków ekonomicznych, ale spowodował także wyraźne zmiany w środowisku przyrodniczym regionu. Te zmiany to głównie szkody górnicze w postaci osiadań, zasolenia wód powierzchniowych czy ruchów górotworu oraz przekształcenia wynikające z procesów technologicznych – np. deponowanie odpadów wydobywczych i przeróbczych na zwałowiskach. Celem artykułu jest ocena wpływu deponowania odpadów górniczych na powierzchnię terenu powiatu mikołowskiego, a także przedstawienie zmian w strukturze przemysłu wydobywczego w skali lokalnej. Treść artykułu zawiera opis budowy geologicznej obszaru badań, przedstawienie stopnia przekształcenia powierzchni terenu przez działalność górniczą, ocenę wpływu deponowanych odpadów na rzeźbę terenu i środowisko przyrodnicze, a także ocenę stanu rekultywacji opisywanych obiektów. Na podstawie badań wykonano przekroje obrazujące wpływ deponowania odpadów na powierzchnię terenu. Zmiany struktury przemysłu wydobywczego w skali lokalnej przedstawiono na przykładzie odzysku węgla z jednego ze zwałowisk, usytuowanego w północnej części powiatu mikołowskiego.
