Coal combustion by-products (stabilizate, FDG gypsum) generated by the thermal power station in Ledvice were tested on an above-level dump of the Bílina Mine in the North Bohemian Brown Coal Basin during the reclamation of its surface for forestry purposes. A part of the experimental object was treated with coal combustion by-products at a dose of 700–1,000 t/ha that were incorporated into the soil profile by very deep ploughing and the other part was left untreated for comparison. A one-year preparatory agrocycle was conducted on the entire experimental object – growing of <I>Leucosinapis alba</i> for green manuring and for reforestation bareroot and container-grown planting material was set out into dug holes [<I>Larix deciduas</I> L., <I>Pinus nigra</I> Arn., <I>Pinus sylvestris</I> L., <I> Quercus robur</I> L., <I>Carpinus betulus</I> L., <I>Acer pseudoplatanus</I> L., <I>Acer platanoides</I> L., <I>Alnus glutinosa</I> (L.) Gaertn., <I>Fraxinus excelsior</I> L., <I>Tilia cordata</I> Mill., <I>Betula verrucosa</I> Ehrh.]. The assessment of the experimental object at the age of 7 years indicated that as a result of the application of stabilizate and FDG gypsum there was an increase in porosity, water-retaining capacity, soil alkalinity and carbonate content; the soil-forming process was characterized by a decrease in soil alkalinity whereas the high alkalinity of the soil horizon treated with this amendment did not negatively influence the growth vitality of most tree species taxa used for reforestation.

The aim of this article is to evaluate the process of terminating the mine water pumping after the liquidation of the Kohinoor II coal mine, situated in the central part of the North Bohemian Brown Coal Basin (NBB) and the subsequent resumption of pumping from the surface after the mine water rise in the area of the former mine to the desired level. We analyzed previously known data, particularly the amount of mine water pumped from the mine area and the surrounding abandoned mines in the past. Further the evaluation of known surrounding abandoned mines aquifer systems, accumulated in the coal seam (underground accumulation of water) and the evaluation of the effect of increasing the water level in the Kohinoor II mine, focusing on the enlargement of the central mine aquifers and the evaluation of the effects of changes in the way of pumping on the surrounding coal seam and its mining with continued safe brown coal mining at the nearby Bílina mine, that can be ensured for at least another 25 years.

In many circles, brown coal continues to be viewed as a cheap source of energy, resulting in numerous investments in new opencast brown coal mines. Such a perception of brown coal energy is only possible if the external costs associated with mining and burning coal are not considered. In past studies, external cost analysis has focused on the external costs of coal burning and associated emissions. This paper focuses on the extraction phase and assesses the external costs to agriculture associated with the resulting depression cone. This paper discusses the difficulties researchers face in estimating agricultural losses resulting from the development of a depression cone due to opencast mineral extraction. In the case of brown coal, the impacts are of a geological, natural-climatic, agricultural-productive, temporal, and spatial nature and result from a multiplicity of interacting factors. Then, a methodology for counting external costs in crop production was proposed. The next section estimates the external costs of crop production arising from the operation of opencast mines in the Konin-Turek brown coal field, which is located in central Poland. The analyses conducted showed a large decrease in grain and potato yields and no effect of the depression cone on sugar beet levels. Including the estimated external costs in the cost of producing electricity from mined brown coal would significantly worsen the profitability of that production.
