Abstract
Abstract In the article there is presented temporary situation of coal mining dumping grounds in Poland – their inventarization, localization and environmental impacts. The coal mining dumping grounds in Poland are situated in three coal basins: Upper Silesian Coal Basin, Lower Silesian Coal Basin and Lublin Coal Basin. In all mentioned areas occur ca. 270 coal mining waste dumps, covering surface of over 4400 ha. The main environmental impacts connected with dumping grounds are fire hazards, water pollution and a danger of slope sliding. The question of recovery of coal from disposed wastes with regard to legal regulations is discussed. There are presented technical methods of coal recovery considering environmental protection issues. There is a necessity and technical possibility of recovery of coal from the coal-mining waste dumps. The coal recovery reduces hazards of self-ignition and fires of the dump. It is also economically justified. The analysis of required regulations in legal system in Poland for safe exploitation of secondary materials from coal mining dumps is done. Socio-economic aspects of recovery of coal are discussed. The valid legal regulations in Poland regulate the issues connected with coal mining dumping grounds in a very general way. It is necessary to prepare supplements to the legal provisions or new regulations concerning post-mining dumping grounds.

The coal mining waste dumps are situated in three coal basins: Upper Silesian are spread within the area of over 4,000 ha in Coal Basin, Lower Silesian Coal Basin and Lublin more than 260 dumping sites, where over 760 Coal Basin
Due to the fact that the amount of coal in the waste material may be up to 10%, it can be estimated that total potential amount of recovered coal from the dumps in the USCB shall account for more than 45 million Mg (GAWOR, 2013, 2014)
