Monitoring of multipoint borehole extensometers and results of physical modelling

Data concerning monitoring the rock bolt heads are in file roof_subsidence.xls (roof subsidence) and Schem&vol-measur2001.xls (distance between the heads of adjacent rock bolts)
Subdirectory Fisical_model contains the data concerning the physical modeling. File Physical_model_fotos.docx presents photos of the all model states, which were selected to digitize the marks positions and then incremental displacements of the marks, namely the difference of the positions between serial (sequential) states. File affin_transform_01.xlsx contains data described affine transformation of the photos. Files *.srf present fields of the incremental displacement of the marks between successive state of the model.
