Abstract

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.

Highlights

One of the major problems of reclamation work in the North Bohemian basin area is the reclamation of the areas contaminated by coal matter, and to a lesser extent with the mine waters and risky organic substances.The occurrence of such areas is largely due to the development of coal seams

This paper presents the characteristics of significantly phytotoxic areas, the prospective sites of claystone sorbents, and assesses the possibilities of their use in the reclamation works

Summary

Introduction

One of the major problems of reclamation work in the North Bohemian basin area is the reclamation of the areas contaminated by coal matter, and to a lesser extent with the mine waters and risky organic substances. The phytotoxicity of these sites is given, in addition to the increased sulfur content, especially with the extremely acidic soil reactions, and requires a specific reclamation methodology. In the area of the North Bohemian basin, there are phytotoxic areas contaminated with coal matter (possibly with other risky organic substances), phytotoxic areas contaminated with acidic mine waters and sterile surfaces with the occurrence of plastic yellow clays at the upper horizon [1]. The phytotoxic areas contaminated by acidic mine waters are quite rare in reclaimed locations In this case, the toxic nature is caused by an extremely acidic soil reaction, a high sulfur content and coal matter. Methods based on the application of claystone sorbents are described in this paper
