Chlor i rtęć w węglu i możliwości ich obniżenia metodami przeróbki mechanicznej
(2007) Aleksa, Henryk; Dyduch, Franciszek; Wierzchowski, Krzysztof
The paper presents the possibilities of reducing the contents of mercury and chlorine in hard coal using the methods applied in mineral engineering. In relation to those elements, their location in the coal structure has been characterized, together with their origin and forms of occurrence. Discussed also are the technical methods of reduction of these contaminants in coal using the gravitational separation, floatation, leaching and dewatering. The proposals presented may find their application in the industry and contribute to reduction of emissions of these substances very harmful to health and environment.
Badania nad możliwością wykorzystania odpadów do produkcji cegieł
(2007) Balaweider, Małgorzata; Marciniak-Kowalska, Jolanta
In mineral mining, in the technological processes of production, the wastes are being created, which are, in many ways, harmful for natural environment dependably on their chemical composition. The purpose of the conducted researches was determination of the possibilities of partial replacement of the ashes produced by thermal-electric power station »Kraków« SA by flotation wastes from limestone copper ores flotation and of production of required quality bricks. The paper presents the researches over bricks, done according to the present norms, which purpose was to determine the applied material accuracy. There is the perspective possibility of flotation wastes, containing a lot of silicon dioxide, application to bricks production.
Kamieniołomy surowców węglanowych w regionie świętokrzyskim przykładem korytarzy ekologicznych
(2007) Barga-Więcławska, Jadwiga
Studies of malacofauna and vegetation in quarries of carbonate rocks in the Swiętokrzyskie region were carried out in the period between 1999-2005. The investigations were conducted on waste heaps and workings, and demonstrated the differences in ecological conditions between heaps and workings. Snail studies were performed using the quantitative method. The study revealed the presence of 57 snail species which constitutes 58% of all snail species occurring in the Świętokrzyskie Mountains. The most abundant snail communities were observed in the »Zygmuntówka« quarry, in »Miedzianka« and »Wietrznia« quarries, and in the area of the historical galena mine on Karczówka in Kielce. Terrains changed by mining are habitats of rare and endangered plant and snail species. The following snail species should be mentioned: Cecilioides acicula, Clausilia bidentata, Acantinula aculeate, Trichi lubomirski, Helix pomatia and Helix lutescens. Nine southern species were identified. Malacofauna of post-mining areas is a manifestation of transformations progressing in natural environment of our region.
Ocena przydatności wybranych testów in situ i badań laboratoryjnych dla identyfikacji i przeciwdziałania procesom geodynamicznym
(2007) Bednarczyk, Zbigniew
Experience connected with usage of different in-situ and laboratory test is described in the paper. It includes recognition of genesis and possibilities in geodynamic processes counteraction. Chosen by the author methods of landslide research, monitoring and modeling in open-cast mines, Norway and flysch Carpathians are presented.
Zagrożenia wodne w kopalniach węgla kamiennego w Górnośląskim Zagłębiu Węglowym w dobie restrukturyzacji górnictwa
(2007) Bukowski, Przemysław
The progressive process of mines abandoning in the USCB from early 90's caused the formation in mine workings of water reservoirs with a capacity of each of millions m3 of retentioned water. Despite the observed decrease of incidents that result from the water hazard during last decade, the water reservoirs that come into existence in mine workings of abandoned mines endanger and will cause even greater hazard for conducted and planned mine workings. Their influence in conditions of various properties of geological environment entail the necessity of changes in an attitude to the assessment of the scale of water hazard and their prognoses, what was presented in general in the article.
