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
