Hydrogeological Analysis of the Tellnes Mine, Norway
MetadataShow full item record
The main purpose of this MSc thesis work is to connect hydrogeological features of themine which can be used to develop a Hydrogeological Model of the Mine. The analyseshave been mainly focusing on the three subjects; response time, pressure increase andreceding time in the sensors as an effect of a major rainfall event. 3D models are builtusing the analyzed data from Ruden AS and SINTEF provided by Titania AS. Theresponse, pressure increase and receding time are all connected to the impact from therainfall events. There is especially one zone where these characteristics are more presentthan in the rest of the mine; in the hanging wall area associated with the boreholesTEL H 10 to TEL H 12. The particularly sensitive piezometers within this region wasthe sensors 11A, 11C, 12B and 12C. These sensors exhibit quick response time, greaterpressure increase on average and a slow drainage represented in receding time. Thisis the main area for previous events and the most probable area where there might bestability challenges in the future. However, with a denser array of boreholes and sensors,the discovery of similar areas might be detected other places in the open pit mine. Incombination with other models, this hydrogeological interpretation can be used as a toolfor enhanced safety.
