ABSTRACT
Comparative analysis of specific closure methods of the underground exploitation of lignite in three distinct areas and with tradition in coal mining in Romania, namely Comanesti – Bacau county, Varzari - Bihor county and Jugur - Arges county, is an opportunity in finding reliable and efficient technical methods of eliminating the effects produced by the mining companies activity. The paper includes the history of each exploitations mentioned, it describes the best practices in closure and remediation of mines, it analyzes in comparison the stratigraphic, hydrologic, geologic and tectonic situation, as also the impact of mining activity upon environmental factors and finally it describes in comparison the technical solution of closure and rehabilitation of each perimeter taken in analysis.
