| Abstrakt: | Abstract: The observation network was built for the repeated determination of spatial position of points by means of the GPS method. It was built on the surface above extracted mining panels near Karviná, to monitor the development of subsidence depression in non-trivial geo-mechanical conditions. Two years of repeated surveying gave us the information about the process of creating of the subsidence depression in such area. The results gained so far show the important influence of the complicated tectonic situation on the behaviour of surface subsidence. A smooth development of subsidence depression without important irregularities was found out on sites without tectonic faults, while on sites where rock mass is disturbed with tectonic faults, the shape of subsidence depression is very irregular. |
