Miroslav SVOBODA, Ph.D.3 1 VŠB – Technical University of Ostrava, Faculty of Mining and Geology, Institute of Environmental Engineering, Czech Republic 2 V ŠB – Technical University of Ostrava, Faculty of Mining and Geology, Institute of Clean Technologies for Extraction and Utilization of Energy Resources, Czech Republic 3 Rosice u Brna, Czech Republic ABSTRACT The paper deals with an application of refuse from black coal mining as land reclamation materials in the Czech Republic. The north-east part of the Czech Republic is the most significant deposit of black coal. Black coal has been mined there for over 200 years. This deposit is found in the southern part of the Upper-Silesian Basin, greater fraction of which lies in Poland (over 75 % of its area). The paper describes the management of fine-grained wastes deposited in settling ponds for further industrial processing, such as energy recovery, beneficiation of the raw materials by re-flotation, utilisation of the raw material in the production of bricks and cement clinker. Fine-grained flotation tailings may also be used as a filling material in the remediation of settling ponds. Keywords: coal mining waste, fine refuse, coal preparation, pelletization of waste INTRODUCTION Underground mining of black coal brings a number of negative impacts which influence both the environment and human health

. Among the most prominent impacts there are changes in the landscape caused by ground subsidence, which may be further responsible for altered biodiversity and required changes as to how land is used. Next, there are frequent changes in the regimes of ground and surface water and it is often gets polluted by mining water, air gets polluted by methane leaks, dust forms when mining waste is handled, etc.

Currently, the public has a rather negative attitude to coal mining as its effects, leading to apparent changes in the landscape and impacts on buildings, are usually emphasised.

What is frequently omitted is the fact that the discovery of coal and its exploitation have contributed to the technical and cultural development of the population in the last 200 years. The use of coal in power generation and in iron and steel production is gradually being replaced by more modern technologies, the so-called clean coal technologies.

In addition, scientific research focuses on the issue of coal mining too, which has a significant economic benefit for the concerned regions. The Ostrava-Karviná District (OKR), which is situated in the north-east part of the Czech Republic, is the most significant deposit of black coal in the Czech Republic. Black coal has been mined there for over 200 years. This deposit is found in the southern part of the Upper-Silesian Basin, greater fraction of which lies in Poland (over 75 % of its area).
