Mapping and modeling of the forgotten cultural heritage in areas affected by anthropogenic activity—case study for the Czech Republics
Published in Mohamad Al Ali, Peter Platko, Advances and Trends in Engineering Sciences and Technologies III, 2019
The Ore Mountains (in German Erzgebirge) are a 130 km long ridge in the north-west part of the Czech Republic and they create a natural border with Germany. In this region there used to be many stone crosses symbolizing character of the spot. On the crossroads there used to be crosses accompanying the wanderers on their way, or resting-stones used for resting along the way. Other crosses could be found by churches, houses, outside the villages or in forests. Such crosses can be labeled as conciliation crosses as they are placed on a spot where someone was murdered or died in an accident. The Czech-German borderland was affected by the transfer of the German speaking inhabitants after the World War 2 (WW2). The towns and villages in this region were never populated as before the WW2 and the change in the number and the origin of the inhabitants has affected the surrounding landscape structure and land use. In relation to the hate of the German-speaking inhabitants, the small historical landmarks were in many cases removed, damaged or completely destroyed shortly after the WW2. The active open-pit mining in the brown-coal basin at the foot of the Ore Mountains is another factor affecting the surrounding landscape. Many villages and towns were destroyed during the past 80 years of active coal mining—and so have disappeared the small historical landmarks.

Opencast coal mining in Kuznetsk Coal Basin is stimulated by launching new mines and restructuring of existing coal pits due to mining conducted in deeper coal beds. Depths of excavation in the latter case tend to increase, just as the amount of removed overburden and waste rock disposed to spoil heaps. More stringent requirements of environmental conservation and sustainability result from the scarcity of areas available for dump structures. This problem is particularly acute in areas of prolonged and vigorous mining, which are distinguished by developed infrastructure, use of various processes, the presence of hydrotechnical and other engineering structures. The problem is solved by increasing the height and capacity of existing spoil heaps, by resorting to out-of-use hydraulic fill areas to accommodate spoil heaps. Besides, there is a trend to use areas poorly suited for agriculture and forestry (such as floodplains of streams and rivers, swamps, hillsides and other inarable lands) for disposal of overburden rock. In most cases, disposal of overburden rock on the ground surface under such conditions leads to the development of high and extra high natural and man-made dump systems, which integrate waterlogged anthropogenic and natural rock masses. The height of spoil heaps in Kuznetsk Coal Basin nowadays can reach 200 m while the average height comprises 100 m. Designs for reconstruction of Bachatsky and Taldinsky open-pit mines provide for an increase in the dump structure height up to 300 m.

The Rydułtowy mine is the oldest active mining plant in the Upper Silesian Coal Basin (USCB) in Poland, one of the largest hard coal mining areas in Europe. The total area of USCB is about 7400 km2 (Popiolek et al. 2001). The largest part of this mine region is located in Poland, and the remainder lies in the Czech Republic. It is located in the southwest part of the USCB, and covers around 46 km2. The location of the study area is illustrated in Figure 2. The first excavation has been dated to 1792, and the average daily production of the mine ranges between 9000 and 9500 t/day. Coal mines in Poland are very deep mines with an average exploitation depth of 800 m. In a presented mine, a depth of extraction is between 800 and 1200 m (Pawluszek-Filipiak and Borkowski 2020a). The residue from the excavation is taken to the Szarlota slag heap, which is formed from post-mining waste. It is 134 m in height and is the largest in Europe, with an area of 37 hectares and a volume of 13.3 million m3 (Pilecka and Szermer-Zaucha 2015). According to the Polish Mining Group, coal in the form of deposits makes up around 80.4 million tonnes, and excavation is expected until around 2040.

The fossil fuel power plant is operating since 1945, and produces nowadays, a fuel power of 815 Gсal/h and an electric power of 331 MW. Although the coal from Kuznetsk coal Basin (Western Siberia) is the predominant energy source for this plant, natural gas is also used. The gaseous and solid emissions are discharged through two 100 m stacks. Even though there are some dust and gas catcher systems to reduce the emissions, the plant emits non-negligible amount of solid particles into the air, especially between November and March when the ambient air temperature ranges from −15°C to −30°C and the heat and electricity for the main part of the city is produced to 75–90% from coal and to 10–25% from natural gas. Moreover, the plant is close to the city centre and intricately linked with residential areas, meaning that power plant area is effectively embraced inside a dense urban network. According to the State report ‘On the State and Environmental Protection of the Tomsk Region (2014)’ [18], the highest air pollution level is related to these specific residential areas, located in the impact area of this fossil fuel thermal power plant. Meteorologically, these emissions are transferred to the city area according to prevailing winds.

Mihaliccik coal deposit is located in Eskisehir, Turkey, as shown in the regional map in Figure 2. Lignite deposits within Beypazari Neogene basin comprise Cayirhan area in the North and Mihaliccik area in the South. Eskisehir-Mihaliccik lignite field extends over an area of 29 km2 within Beypazari coal basin [33]. Cayirhan field has two different lignite levels; top and sub, whereas Mihaliccik field has only top lignite level. Coal thickness in Mihaliccik lignite field is 6 m at most. The coal thickness shows gradual increase from edges to the centre of the field. Mihaliccik lignite field is restricted with a growth fault in the South. Depending on this growth fault, coal thickness shows abrupt terrestrial increase from North to South [34,35].
