Mining has a long history in Romania, dating back to 100 years B.C.E., with gold and silver ores being some
of the country’s riches. Over time, the economically-viable ore reserves became exhausted and the ore mines
became unprofitable to operate. Due to this situation, the best option for the state was considered to be the
ecological rehabilitation and closure of these non-profitable mines. The main steps for ecological
rehabilitation and mine closure are elaboration of the mine closure plan, elaboration of the technical
project, selection of the entrepreneur, execution of the works, warranty period (two years), and post-closure
monitoring. All these responsibilities are established by Romanian law, and provide assurance concerning
project sustainability to all stakeholders concerned. This will be the challenge for more than 450 mines that
will be closed in Romania over the next 10 years, with a financial provision of approximately
US$400 million. By way of example, this paper presents the monitoring programme for Baia de Aries Mine,
where mining activity ceased in 2003. The principles used in developing this monitoring programme will be
applied in all the mine closure activities in Romania.
