Slopes stability is one of the decisive factors influencing the results of the mining company in extraction process. Methods used for the years 1980 - 1985 are suitably supplemented by new monitoring methods due to the development of techniques. Before practical application of new methods, are these investigated in the mining conditions and verify their validity and applicability. Achieved results will be compared with results from proven methods. Following new methods of monitoring are used and tested on opencast mine CSA, Litvinovska uhelna a.s.: automatic monitoring system with the total station (since 2005), ground laserscanning, reflectorless measurement and remote sensing - method of radar interferometry. The goal of the deployment of automatic monitoring system is to ensure monitoring continuity of selected areas in the side slopes of the brown opencast mine CSA, including an evaluation of the spatial variation of observed points and subsequent transfer of the measurements results to the operational control room. Up to now there were four stages of reflectorless measurements. Achievements of reflectorless measurements over four months in 2009 are presented in this article. Results will be used in further advancement of the opencast mine CSA and in the extraction of sand stone in quarry Javorka. [ABSTRACT FROM AUTHOR]
