Brown coal mine CSA is situated in north of Czech republic, surrouded by Ore mountains. Mining activity here takes more than 100 years. Seven villages and one lake was ruined in this location. In CSA mine the most quality coal in CZ is mined. In 1960 communist government decided to join some small mines here and make one big mine with surface mining. Golden age of mine was in 80´s, nearly 10 mil of tons were mined by more than 3500 workers here. Mine has some limitations today, which will be again discussed in 2020 year. It is not only question of nature and pollution, but also question of people who can find work here. After depleting of coal, restoration lake will be made here. Slow restoration is in progress from west side of mining area.
