in the 1990s, mining operations entered a restructuring process that had a very strong social and economic impact on the city. A large number of mines were closed, and this also affected other related activities, such as suppliers of materials, equipment and services, and agents that operated in the trade and services areas. Nevertheless, in recent years, new areas of economic development emerged, such as tourism, forestry industry, bakery industry, and commerce. The city's remaining active mine is the Lupeni Coal Mine managed by the Petroșani-based National Hard Coal Company.
