Vyhodnocení stability bočních svahů lomu ČSA, Litvínovská uhelná, a.s.

Abstract

The dissertation thesis deals with the monitoring method of the open-cast mine ČSA, Litvinovska uhelna a.s. Results of monitoring and map data are input data in process of slopes stability evaluating. The first part features the reason and genesis of monitoring, used methods, their range and development. The second part describes the implementation of new geodetical method used till year 2004. Next chapters mention the process and the verification research results from new monitoring and geodetical methods that were done in 2005-2010 in running conditions of open-cast soft-coal mine. Proposal for their next usage during monitoring of the side slopes of the open-pit are presented and evaluated here. There is also the project methods optimization and their utilization for mining plan of open-pit ČSA. In the last part there is the calculation of side slopes stableness and the assessment of new methods bonuses during scoring steadiness.
