Determination of the rock mass resistance index (GSI) based on image processing

More and more often, on an increasingly large scale, the geological resistance index (GSI) system is used for design practice of mining process. The GSI, a unique classifying mass rocks, linked to parameters rock strength distortion, based generalized criteria Hoek-Brown MohrCoulomb. GSI can be estimated using standard in situ tables by direct surface observations underground or mining. value provides numerical representation overall Geotechnical quality mass. method determining photographic images mass, with image processing technology, fractal theory artificial neuronal network (ANN), already known successfully applied several projects.
