The research project no. TA01020592 "Impacts on microclimate, fresh air quality, ecosystems, water and soil at the hydric reclamation of abandoned lignite quarries", supported by the Technologic Agency of the Czech Republic, was going on within the year 2011-2014. The monitoring of the locality conditions with a target to record the formation and character of biocenosis and to estimate the appropriate ecological potential of locality on basis of the elements of biological quality was carried on during the continual flooding of the future Most Lake. In addition the project enabled the monitoring of water quality and the composition of originated water...

The filling phase of the Most Lake is currently completely finished. The Lake was formed by the flooding of the residual pit of Most-Ležáky quarry in which the brown coal mining was terminated on the 31st December 1999. The filling phase of the Most Lake was initiated on the 24th October 2008. The research and development project "Impacts on microclimate, fresh air quality, ecosystems, water and soil at the hydric reclamation of abandoned lignite quarries" evaluated the significance of the influence of the microclimate development on the fresh air quality in the area around the Lake. The project was carried out in the period of 2011 to 2014. The results...

The article briefly summarises first results of the restoration issue in the new project. The general characteristics of the new project, the methodology of the terrain works, laboratory analyses, methodology of the research areas selection and their basic characteristics are shown in the first part of this article. The main part of the article is devoted to the evaluation of three succession areas situated in the Radovesice dump and the Pokrok dump. The geological, pedological and biological situation of these areas and the first conclusions about the long term development of the soil profile are summarised in this part of the article. Very slow improving...

Part of sulphur, nitrogen and oxygen compounds contained in the processed raw material is transformed into volatile products. Therefore liquid pyrolysis products often contain high concentrations of oxygen, nitrogen and sulphur bound in the form of organic compounds. It is one of the causes of the high reactivity of these products leading to the gradual polymerization, polycondensation and other reactions resulting in an increasing average molecular weight of liquid product of pyrolysis and often in formation of substances in the solid form. It is therefore important to reduce the content of oxygen, nitrogen and sulphur bound in the form of volatile...
