Deformometric and leveling measurements in the cadastral area of Dětmarovice village in 2019
Kajzar, Vlastimil
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 2019 was carried out in March, the second during October.

Deformometric and leveling measurements in the cadastral area of Dětmarovice village in 2018
Kajzar, Vlastimil
Institute of Geonics AS CR, v.v.i. in 2001, in connection with the underground mining of coal reserves and its possible influence on the cadastral area of Dětmarovice, Ostrava was asked in 2001 to assess the possible impacts of undermining on the stability of slopes on selected parts of the cadastral territory of Dětmarovice. Consequences of the mining are, among other things, surface drops, which, due to the existing morphology of the terrain in the cadastral area in question, raised the concern that these declines would not further induce sloping movements.\nIn November 2001, a monitoring monitoring network of four individual profiles was built in the locality. On these lines it was recommended to perform deformometric (longitudinal) and leveling measurements at the same intervals. From the subsequent periodic deformometric and leveling monitoring of these slopes before the development of the descending basin into the monitored area and then during the period of manifestation of the effects of the mining, it is possible to determine whether the slope deformations develop at all and then to point out the possible causes of possible movements (morphological-geotechnical and climatic conditions, mining and anthropogenic activity, etc.).
