The first part of this two-part´s article has seven chapters, describing the reasons for the design and construction of the "Ervěnice corridor" (EC or EK in the Czech language) - of the earth dump body with the height over 130 m and the length of approximately 5 000 m. The corridor was built by the mining way from the non-compressed clay in the years 1957-1984 and its main significance lies in the road and railway connection between industrial agglomeration and the cities Most and Chomutov. In the years 1981-1984, the important links were localised on its top: the railroad Most-Chomutov, road I/13, and then pipe bypass of the Bílina River. The first...

A long-term research focused on the contamination of new soils of the oldest and most important anthropogenic dumps in the Most basin by risk trace elements was carried out in the years 1998 -2013. According to the obtained results this contamination can be considered as low significant. The content of arzenic higher than the limit is the most problematic for several earth profiles in the studied area remediated for the agricultural utilization. The evaluation of the soil contamination of the Most Lake coast and slopes was the second topic of this study carried out in the years 2012 - 2013. No dangerous higher contents of this risk elements were found...

The article provides summarizing information focused on the tendency of spontaneous combustion of deposited brown coal and the forecasting of outbreaks of self-ignition in the stored coal fuels. The study was carried out in the project TA01020351 in the frame of the programme ALFA. The outputs and partial knowledge from complex long-term measurements conducted at brown coal producers in the years 2011 to 2013 are described gradually. This article ties up to the previously published papers with this topic and its aim is to briefly gather all carried out tasks and outputs.
Research and application of indicator gases of coal spontaneous combustion in China

China is currently the most important producer of coal globally with a predominance of underground mining. Numerous mines here benefits the seam prone to spontaneous combustion, which are a source of risk of endogenous fires. The beginnings of the research and application of indicator gases in coal spontaneous combustion in China comes from the sixties of the last century. The further significant development occurred in the 1990s, when the national research programme "Characterization of the oxygen adsorption of coal and its application in the prevention of mine fires" was completed. The article briefly describes an overview of the historical development...
