Abstract

The North-Bohemian Basin area is known for its largest Czech brown coal deposit. About 50\% brown coal reserves have been exploited in the North-Bohemian Basin by the mining company of Severoceske doly, a.s. (North Bohemian Mines) today. The opencast mining of brown coal naturally led to vast landscape damages. Therefore reclamation work has acquired great significance. The specific feature of Severoceske doly, a.s. mining is the fact that the mining has been realized in two geologically absolutely different localities. This fact demands even rather different methods of reclamations. The difficulty in the reclamation of Severoceske doly, a.s. external and internal dumps consists in the extremely severe properties of rocks in most of the dumps. That is the reason of the application of some non – traditional restoration methods. This report briefly summarises the experience in application of fertilizable soils, power plant stabilizer, power plant ash and aerial sowing of charlock. The results are documented by the longterm monitoring of the physical, mineralogical and pedological parameters of rocks in testing areas. The work was developed with the support of the Czech Republic Ministry of Education, Youth and Physical Training within the research plan No. MSM 4456918101 Research of Physical-Chemical Properties of Masses Affected by Coal Exploitation and Utilization and their Influences on Environment in North-Western Bohemia Region.
