The Lake Most is located in the central part of the Most Basin (Czech Rep.), which is a geomorphological part of Eger graben. The lake was created by flooding of Most-Ležáky residual pit between October 2008 and September 2014. Like in rest of Europe, the safety and the security of mine lakes is one of the priorities of flooding and post-flooding period. One of the main hazards identified is the slope stability of lake banks. To develop a reliability methodology for assessing the long-term stability of flooded open pit mines, a large-scale numerical model of the lake was carried out and was applied on Lake Most. The large-scale numerical model was...

In the past, secondary energy products were mainly used for construction purposes and as a material suitable for landscaping during levelling off traces of mining activity. For these purposes, large quantities of these materials are deposited at disposal sites near especially large energy sources. At the same time, due to the demand for raw materials and a significant shift in technology, new alternative sources of various elements are also being searched for. Their need is increasing with the development of their use, especially in electrical engineering. This article describes the analysis of a selected repository in the ústí Region with regard to...
