The article provides a summary of the determined fundamental properties and chemical composition of solid products after combustion of brown coal and biomass, which will serve as a basis for the assessment of the applicability of these products in reclamation works, in particular in the areas of large surface mines and localities otherwise affected by industrial activity. The results show that this substances are potentially interesting material, but thanks to the variable composition, they have to be characterized in detail before they are used to avoid the negative impact on the environment. The carried out works are partial results of the project...
Summary of the Mineralogical situation of surface mine ČSA and the new findings from the years 2015-2016

The open pit mine Československé Armády is one of the most important mining localities of the Most Basin up to these days. Thanks to the gradual termination of overburden rocks mining, it is a good time to summarise the long term mineralogical research of this locality. The article briefly evaluates the history, the geological and mineralogical situation of the open pit mine Československé Armády. The main attention is devoted to the two new mineralogical discoveries in 2015 and 2016. The newly discovered sample of cordierite is described as the 63rd mineral of the Most Basin.
Deep penetrating probes on the internal dump of the surface mine Jiří

Every penetrating probe that meets deep condition h > 50 m can generally be considered as a deep. The article, however, deals with penetrating probes, which are close to the depth of 100 m or even exceed it. The location of interest currently achieves in its central part the thickness of 120 m. The company Penetra, s.r.o. has developed the technology to implement extremely deep penetration probes, so that even for this thickness of the dump they are able to provide measurements, which fulfils its purpose. The tables document the development of an unprecedented large-scale penetration survey of the internal dump Jiří, which makes this dump the most...
The role of dendrochronology in the engineering-geology research of landslides within the Most basin

Zpravodaj Hnědé uhlí 2016, 56(3)
Dendrochronology is a method of the absolute dating based on the evaluation of the response of woody plants to different natural processes, e.g., mass movements, debris flows, avalanches, floods, erosion and volcanic events. Tree-ring width analysis as well as quantitative wood anatomy allow reconstruction of the former natural processes, together with their impact, magnitude, severity and frequency. This article describes how dendrochronology can be used in the natural hazard research in specific conditions of anthropogenic relief of the Most basin. Results of case studies performed during the last two decades are presented as well.
