ADVERSE SUBSIDENCE IN MINING AREAS - RECLAMATION OPTIONS

Abstract

Coal mining causes undesirable terrain subsidence due to caving in of the overlying rocks into the already excavated space. Subsidence deforms the terrain, damages structures on the surface and water flows, which results in the formation of inaccessible wetlands and swamps, and these areas need to be reclaimed. The problem of large flooded areas as a result of mining activities also concerns an area known as пїЅKozinecпїЅ, which is located between KarvinпїЅ and Doubrava in the Czech Republic. That territory has long been affected by mining in the Mining Plant 1. In пїЅKozinecпїЅ, the subsidence reached up to 7 metres. Since this site has great natural value, it seemed desirable to reclaim the area. As early as in 2009, work on individual projects involving reclamation activities began. The projects also included proposals of islands and peninsulas that would be placed in the flooded area. Individual projects are designed so that sustainable development is maintained within the entire territory after the completion of reclamation projects. It is, therefore, a measure for the preservation of the environment for future generations in the least altered form. The article, deals with the design of the reclamation of the area influenced by the mining activity. The paper includes visualization of the designs of individual landscaping.
