Gyttja, Gyttja with Coal and Calcareous Gytta with Coal are very crucial aquifers for the basin. Water content of the gyttja series are very high, On the contrary, permeability of Gyttja series is very low and water trapped locally in the pockets of gyttja behaves as a pressurized aquifer. The contains pressurized water. Total stations involve two reference locations and nine prisms. Figure 5 shows the planimetric view of the pit with the locations of IBIS-M radar and total stations. 3.1.2 Geotechnical Backround The geotechnical model of the mine area was revised after the two catastrophic mass movements occurred in February 2011. In 2007 five geotechnical boreholes were drilled and 57 undisturbed samples using Shelby tubes were taken. Undisturbed sample were sent to soil mechanics laboratory of the METU. In 2011, 362 undisturbed samples using Shelby tubes were taken at 7 different locations and they were tested by METU Soil Mechanic Lab. The geotechnical parameters derived from this test campaign are listed in Table 1. Table 1. Principal Geotechnical Parameters 3.2 Analysis of Radar Data Shortly after the two mass movements of February 2011, a slope monitoring network was implemented to detect possible further slope movements. The current mine monitoring system consists of two robotic total stations and one IBIS-M unit. Figure 5. Planimetric view of mine. IBIS-M wide coverage makes it possible to cover the entire area of interest from a permanent installation on the opposite side of the pit. Robotic total stations, although one of the most diffuse monitoring tool for surface movements, present some limitations: Low accuracy of measurements ( e.g. a tolerance of ±2cm at 1.000m measurements distance) Measurements affected by weather conditions (snowy, foggy days effects the measurements precision.) Not possible to measure movements in real-time necessary for critical monitoring. These limitations are overcome by slope monitoring radar, which ensures submillimetric accuracy, operability under all weather conditions and real-time active monitoring with customizable alarming capabilities. 114
23 rd The broad area coverage makes it possible to monitor the pit wall from a semipermanent installation on the opposite side of the pit, at a working distance of about 2 km (Fig. 6). November 2011 Figure 6. IBIS-M installation at Çollölar. During the monitoring period June 2011- January 2012 IBIS-M was able to pick up several moving areas highlighted in Figure 7. From radar data it is possible to observe a general stability of the pit with a few areas of localized movement. The most active areas have been Area 3, Area 4 and Area 6.

Monthly cumulative displacement radar maps covering the period from June 2011 to January 2012, highlighted in red the areas of movement. 115
