Clay Sorbents in the Area of the Most and Sokolov Basins as a Possible Use in Agriculture Reclamations

This paper is devoted to the possibilities of the reclamation use of claystone sorbents of the Most and Sokolov basins. The properties of phytotoxic areas suitable for the application of sorbents, the locality, and parameters of the main clay sorbents of both brown coal basins are briefly summarized in the paper. Clay sorbents are suitable for the reclamation of phytotoxic surfaces contaminated by coal. This paper provides a brief evaluation of the properties of the claystone sorbents of the North Bohemian and Sokolov basins. In the region of the North Bohemian brown coal basin, potential sorbents can be used for the reclamation works.

Evaluation of the Forest Reclamation of the Anthroposoil Dump at the Bilina Mines Created from Marlstone

When reclaiming the surface of the Radovesická dump in the North Bohemian brown coal basin, the most commonly used marls and marlstones are extracted in the foreland of filled-in territory. The most frequent reclamations are the formation of overgrown and humus anthroposoil. The soil properties of the anthroposoils for forestry purposes and the growth vitality of a broader assortment of woody plants in the age of 12 - 14 years are evaluated. It has been found that the very good growth vitality on these anthroposoils is shown by most of the trees of domestic origin (Populus nigra L., Acer pseudoplatanus L., Pinus sylvestris L., Alnus glutinosa (L.) Gaertn., Fraxinus excelsior L., Betula verrucosa Ehrh., Quercus robur L., Tilia cordata Mill.), including some of the tree species introduced (Larix decidua L., Pinus nigra Arn.) and reclamations of atypical atrophic soil horizons did not negatively affect their development.

The Methodology of Melioration and Restoration of the Largest Dumps of the Most Coal Basin

Reclamations of dumps in the Most Basin that is located in the North Bohemia consist of restoration of extremely unfavourable properties of rocks that are poured down onto the dump body. These rocks come from the surface layer and the layer where coal bed is present. Sands, clay sands and kaolin (illitic clays) are the main components that occur in the material. Other components are predominantly organic (coal) mass, siderite and pyrite. This report briefly summarizes the history and present of ore, non-metallic and coal mining in the region and addresses in detail the issue of moderating the consequences of mining, which is one of the principal activities of the Research Institute for Brown Coal, j.s.c. in Most. The concept of landscape reclamation in the largest dumps after mining ends, the technical reclamation methodology and the well considered use of fertilizable soil are main results presented in this article.

Summary of Experience from the Long-Term Pedological Research on the Banks and Slopes of Lake Most

This paper briefly assesses the conclusions from the long-term research of soil properties of the banks and shore of Lake Most. This paper mainly deals with the long-term development of the soil parameters of the anthropogenic soil profile and, to a lesser extent, the assessment of soil habitats with a typical flora. The experience gained will aid in the planning of further hydrological reclamation.

Sorbent Mineralogy in the Most Basin and Their Utilization for Reclamation Works

The contribution is focused on the relation between sorptive efficiency, mineral structure, and reclamation extraction of clay sorbents originating from the Most Basin. Clay sorbents are an important accessory raw material that occurs on several localities in the North Bohemian Brown Coal Basin, which are briefly described in the first part of the paper. The results from clay sorbents were obtained by mineralogy survey based on a diffract analysis with a D 5000 Siemens X-ray diffractometer. Localities, where zeolites and montmorillonites were found, are the main subjects of the research. The results show that parameters of clay sorbents mined in these localities are suitable for reclamation works. A successful reclamation with the use of bentonites is demonstrated on Strimice dump.
