CONCEPT OF FIBRE OPTICS GEOTECHNICAL DEFORMATION MONITORING AND IN-SITU DEPLOYMENT IN OPEN CAST MINE

Popis výsledku v původním jazyce

The paper presents a concept of Fiber Bragg Grating sensors (FBG) and Brillouin Optical Time Domain Reflectometry (BOTDR) application for deformation monitoring on a side slope of an open cast mine. The fiber optics measurement techniques, instruments ofour own construction and methods of instrumentations developed within two past research projects were used in-situ. Different means of geotechnical instrumentation for subsoil deformation monitoring were installed in a former open-cast-mine in the CzechRepublic in order to test our instrumentations and to gather information about the mine slope behavior. The first type is the sub-surface monitoring of the potentially unstable area and the second one is performed in boreholes to determine a slip surface location and to describe deformation development in time. The instrumentations were done both with fiber optics and geotechnical deformation measurement tools, so that the results can be cross-checked. FBG sub-surface extensometer for s
