Stability of old mine workings of Jeroným Mine at Čistá, Sokolov District

The Jeroným Mine, which is situated in the locality of Slavkovský les Protected Landscape Area, is a unique heritage site associated with mining in the 15th and 16th centuries. To make this mine working accessible to the public, it is necessary in the first place to stabilize underground voids and to ensure such internal microclimatic conditions that any degradation of the mine working and any hazard to workers performing restoration operations and later to visitors will not occur. The contribution deals with factors conditioning and affecting the stability of this system of mine workings.
