ABSTRACT

The difficulty in reclamation of the North Bohemian Basin dumps consists in extremely
severe properties of rocks in most of the dumps. It mainly concerns the rocks of the
overlaying formation and the formation of brown coal seams. Sands, kaolinitic clayey
sands and kaolinitic and illitic clays are the main materials bulk to the dumps. The
admixtures of the bulk rocks consist of organic coal, siderite and pyrite. These rocks are
mechanically unstable against wind and water erosion and they have obtained adverse,
acid up to phyto-toxic character. The Radovesice dump is a typical example of this
situation.

The report summarizes the history, present and perspective of reclamation of the
Radovesice dump. The main attention is devoted to application of modern reclamation
methodology, first of all to application of marles and marlites and to foundation of areas
retained to a natural succession.
