Monitoring the deformations in ilgin-çavuşcugöl lignite open pit mine slopes by geodetic methods and mathematical modelling

Slope failure may occur in slopes of open pits slopes, engineering design, highway and railway cuts and natural slopes in case of instability. These failures result in loss of life, economic losses and deterioration of the geometry. In order to prevent these undesired results, monitoring the instability on the slopes is essential safety enhancement geotechnical revisions, rock fall prevention systems etc. must be established according to the results of monitoring studies. This study was carried out in TKİ Ilgın-Çavuşcugöl lignite open pit mine. As a result of the inspections carried out in the mine tension cracks were seen on the eastern slopes which is 60 m far from TCDD Çavuşcugöl train station. Slope movements were monitored at certain intervals in a period of 112 days by using geodetic measurement method as a monitoring system. Deformation data of the slope were evaluated and a mathematical equation based on these movements was then developed.
