The main impacts on the landscape due to coal mining in the Czech part of the Upper Silesian basin are ground subsidence and manmade landscape changes related to the mining. Two measurement techniques were used to determine the values of subsidence; these were then compared together to verify the results obtained. The first, differential SAR interferometry (dInSAR), a remote sensing method, was applied by Gamma Remote Sensing in the frame of ESA GMES Project Terrafirma, using ALOS PALSAR data. The second was the GPS fast static method, which was provided by the Institute of Geonics AS CR. The GPS monitoring was established at a locality near Karviná in 2006. A comparison of the results is described on one subsidence depression created above a panel mined from February 2007 to May 2008. Aspects of the comparison applying to the subsidence measurements are discussed along with the advantages and disadvantages of both methods.
Presented contribution introduces our current utilization knowledge of the pulse scanner Leica ScanStation C10 in situ mine workings. It is a device with a long-range laser beam that has excellent positional, length and angular accuracy and a very high speed laser scanning with a possibility of photographic documentation of scanned scene. The possibility of its use in mining conditions was tested in mine workings in closed polymetallic deposit of Zlaté Hory (Olomouc region, Czech Republic). Within realized surveying campaigns, the possibilities of using this technology were verified, especially for documentation of the current technical condition of the mines and their real spatial definition. Furthermore, it is possible to monitor and determine the spatial changes in mine features (movements and deformations). The analysis of the data based on the undertaken scanning campaigns and also with regard to the physical and technical constraints that were encountered, the technological procedures of each type of scanning were subsequently adjusted to the specific conditions.
