dc.description.abstract | The main purpose of this MSc thesis work is to connect hydrogeological features of the
mine which can be used to develop a Hydrogeological Model of the Mine. The analyses
have been mainly focusing on the three subjects; response time, pressure increase and
receding time in the sensors as an effect of a major rainfall event. 3D models are built
using the analyzed data from Ruden AS and SINTEF provided by Titania AS. The
response, pressure increase and receding time are all connected to the impact from the
rainfall events. There is especially one zone where these characteristics are more present
than in the rest of the mine; in the hanging wall area associated with the boreholes
TEL H 10 to TEL H 12. The particularly sensitive piezometers within this region was
the sensors 11A, 11C, 12B and 12C. These sensors exhibit quick response time, greater
pressure increase on average and a slow drainage represented in receding time. This
is the main area for previous events and the most probable area where there might be
stability 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. In
combination with other models, this hydrogeological interpretation can be used as a tool
for enhanced safety. | en |
