Abstract The paper presents physical and water properties of six soils located in the areas directly adjacent to “Drzewce” lignite open cast mine (KWB Konin). The conducted works included preparation of pits of various soil types in points characteristic to large and representative soil allotments. The selected soil types represented mineral and organic soils. Samples of disturbed and undisturbed structure were taken from various genetic horizons for laboratory analysis. Such properties as content of total carbon, texture, specific density, bulk density, total and drainage porosity, moisture, saturated hydraulic conductivity, the potential of water bonding, total and readily available water, and total retention were determined in the samples from the horizons of 0–100 cm. The investigated soils showed mostly sandy texture with few local loam insertions. Texture and the content of organic matter were the most important parameters which influenced all analyzed properties. Morphology and the properties of the examined soils as well as deep level of soil – ground water were decisive factors when categorizing them as a precipitation-water type. Such soils will not undergo degradation caused by the dehydrating depression cone of open cast mine.

Abstract The present study reports new localities of four liverwort species, i.e., Fossombronia foveolata Lindb., Gymnocolea inflata (Huds.) Dumort., Leiomylia anomala (Hook.) J.J. Engel & Braggins and Odontoschisma denudatum (Mart.) Dumort., found in Central Poland. The new sites are situated in peat bog habitats and swamp forest in the depression cone of lignite opencast mine near Bełchatów in Central Poland. All of the reported species are very rare and have only few localities in Central Poland.

Open Cast

Nowadays there is a tendency in the world industry to increase the number of open cast mines and the depth of work performed in them. In this regard, the problems of reliable and environmentally friendly transportation of extracted resources become especially urgent. Traditional motor vehicles is quite expensive, have problems with reliability and leads to a large gas pollution of the atmosphere, as well as the associated necessary stoppages of the open cast mine, which in turn leads to significant economic costs. The most optimal solution to these problems is the use of long conveyor lines for transportation. However, it is necessary to solve a number of problems one of them is related to the efficiency of the conveyor, which has a large length. This system needs to be controlled and monitored in real time. Thus, it is necessary to implement an automation system that meets all the specified requirements.

Abstract Kędzior, A. and Popa, E.M. 2013. Sedimentology of the Early Jurassic terrestrial Steierdorf Formation in Anina, Colonia Cehă Quarry, South Carpathians, Romania. Acta Geologica Polonica, 63 (2), 175-199. Warszawa. The continental, coal bearing Steierdorf Formation, Hettangian - Sinemurian in age, is included in the Mesozoic cover of the Reşiţa Basin, Getic Nappe, South Carpathians, Romania. The Steierdorf Formation can be studied in Anina, a coal mining center and an exceptional locality for Early Jurassic flora and fauna, occurring in the middle of the Reşiţa Basin. This paper presents the results of sedimentological, stratigraphical and paleobotanical researches undertaken in Colonia Cehă open cast mine in Anina, where the Steierdorf Formation outcrops widely. Several sedimentary facies associations have been described, these associations permitting the reconstruction of various depositional systems such as alluvial fans, braided and meandering river systems, as well as lacustrine and coal generating marsh systems of the Steierdorf Formation. The sedimentary associations recorded within the Steierdorf Formation show a gradual fining upward trend, pointing to a rising marine water table and a decreasing relief within the source area.
