The purpose of the paper is inventarization, mapping and valorization of coal mining waste dumps, which occur in the area of Gliwice city (southern Poland, NW part of USCB), for the needs of reclamation and management of examined objects and defining potential recovery of coal from the dumps. Valorization of post-mining waste dumps has been done using original methodology, considering problems of reclamation, management, accessibility of the dumps as well as environmental hazards. On three valorized post-mining wa...
