Relics of manual rock disintegration in historical underground spaces and their presentation in mining tourism.

The article chronologically and methodically describes relics of the manual underground excavation preserved on the walls of the Slovak underground works. The analyzed relics a manual excavation may be used as geotouristic objects. These attractive micro shapes hardly identified in the underground by visitors, are presented only in Banská Štiavnica Mining Museum. We offer examples of relics after the manual disintegration of rocks in the underground, according to the development of the technology of the disintegration and hardness of rocks. As a result of our long-term studies of the underground, in the main part of this article we describe examples from Slovak territory. Presented can serve as a basic guide for geotourism reason, while visiting underground. Furthermore, it makes easier the identification of historical technology used for the rock disintegration and explains the various genesis of relics to experts, tourist guides and visitors.
