This paper summarises the results of an inventory of abandoned underground mines within the Nízký Jeseník Upland (Czechia, Central Europe). The area has a long and complex history of mining. During the period between the 11th and 13th centuries, the upland was the centre of ore mining, and later, during the 18th and 19th centuries, it transitioned into slate mining for roofing. From 2016 through 2018, we collected detailed data from 137 mines to better understand their parameters and functioning within the contemporary landscape. The data were mainly focused on the geomorphic character of underground mines, as the existing inventories focus on various other aspects. The results were processed into an interactive web map using ArcGIS Online’s online mapping software. Relations between parameters were assessed using three methods: theχ2 test for a contingency table, ANOVA and linear regression.
