ABSTRACT

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.
