Deformometric and leveling measurements in the cadastral area of Dětmarovice village in 2020
Kajzar, Vlastimil ; Staš, Lubomír ; Foldyna, Josef
Institute of Geonics AS CR, v.v.i. in Ostrava was in 2001 asked by the ČSA Mine, in connection with the considered underground mining of coal reserves and its possible impact on the cadastral district of Dětmarovice, to assess the possible effects of undermining on slope stability in selected parts of the cadastral district of Dětmarovice. Mining results in, among other things, surface subsidence, which, given the existing terrain morphology in the cadastral area, has raised concerns as to whether these subsidence will further induce slope movements. Thus, in November 2001, a monitoring monitoring network with four individual profiles was established in the area. On these lines it was recommended to perform deformometric (length) and leveling (height) measurements at the same intervals. The first of a pair of planned deformometric and height measurements in 2020 was carried out in May, the second during October.
