“…measurements of the groundwater level were conducted. The usefulness of such measurements was confirmed in previous studies (Owczarzak et al, 2008(Owczarzak et al, , 2017. These parameters provide key information that is used to infer the impact of the excavation operation on the surrounding areas.…”

In terms of the mutual arrangement of individual properties, alluvial soils are unpredictable and do not fi t into the regularities most often found in arable soils. Often, soil density does not increase with the sampling depth, and the carbon content in endopedons is irregularly distributed, in line with the quality of alluvial deposits. These soils may react differently to the lowering of the groundwater table, especially in the case of fi ne textured and very fi ne textured alluvial soils. The paper presents selected physical and water properties of fi ne textured alluvial soils in the middle proglacial stream valley of the Warta River (central Poland, near Koło). Seven soil profi les were made. During fi eld studies, taxonomic and soil suitability classifi cations of the analyzed soils were carried out. These were: humic proper alluvial soils, typical humic alluvial soils, and rusty humic alluvial soils. The investigated soils were occupied by grasslands of the 4th and 5th valuation class. The following properties were determined: texture, organic matter content, content of total carbon and total nitrogen, particle density, bulk density, total and drainage porosity, saturated hydraulic conductivity, moisture at particular soil water potentials, total and readily available water, soil reaction in H 2 O and in KCl. Most of them were strongly infl uenced by the alluvial genesis of the studied soils, and more specifi cally -the type and nature of the river deposits that formed the individual genetic horizons, yet they can be considered as characteristic of cultivated soils with a similar texture, occurring in the Central Polish Lowlands. The susceptibility of these soils to drainage degradation was determined due to their location in the marginal zone of the depression cone of the lignite mine "Drzewce". It was found that the top horizons of these soils has undergone the decession process due to their natural and meliorative drainage in the past. Therefore, such soils cannot be subject to drainage mine productivity degradation.

“…Smaller fluctuations most often result from seasonal changes that result from climatic conditions, e.g. precipitation, temperature, evaporation (Owczarzak et al, 2017). Therefore, if there is a rapid decrease in the soil-ground water level after the implementation of the mine drainage barrier, this will indicate that the mine is the cause of this change (see Rząsa et al, 1999).…”

Open-pit lignite mining requires drainage of the deposit. The depression cone, formed as a result of these activities, has a varied surface and depth, and these features are shaped primarily by the geological structure and by the thickness of the caprock layer. In some of the areas covered by the depression cone, soil productivity may deteriorate, and a related yield reduction may occur, providing the basis for the payment of applied compensations for the owners of such areas. The aim of the study was to assess the condition of selected soils in the vicinity of the planned excavation (Field B) of the Drzewce lignite open pit mine (central Poland). Six profi les were excavated in organic and mineral-organic soils. The locations of the test points were chosen to represent soils that meet the criteria of habitats prone to drainage degradation. The morphological structure of the studied soils and their analysed properties indicate that they have already been drained (probably due to the infl uence of climate and cultivation), but does not exclude the possible acceleration and enhancement of this process by the commencement of mining activities. For most of the analysed features, a high correlation between their value and organic matter content was observed. Given that the possible commencement of opencast mining operations may signifi cantly accelerate and enhance the already initiated mursh-forming process, it is reasonable to conduct systematic research at the measuring points proposed in the study.

“…In the ongoing discussion, the most popular subject is the impact of open-pit mining on the level of soil moisture. Most of the authors [130][131][132][133][134][135][136] claim that there is no negative impact of cones of depression on the upper layers of the terrain and they concentrate on the negative effects of the cones on deeper layers. However, a significant decline in levels of groundwater is noticed [137].…”

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.
