The study presents the history of excavation - the formation of the mining underground on the southern slopes of the second highest mountain in Ďumbierske Tatry in Slovakia. An extreme combination of landscape features has created a difficult environment for medieval miners, so they had some problems to excavation deeper mines. On the base of terrain mining relicts we identified the first underground mining spaces from the 13th century. The real development of deep mining was started in the 16th century in Ďumbierske Tatry. The excavation of the underground spaces by manual disconnection and deep mining too stagnated in the end of the 18th century. In the studied area we identified (from the Vážna valley on the West, to the Štiavnička valley on the east) 32 mining localities with excavated historic mining underground.
