THE OPTIMIZATION OF TECHNOLOGICAL MINING PARAMETERS IN QUARRY FOR DIMENSION STONE BLOCKS QUALITY IMPROVEMENT BASED ON PHOTOGRAMMETRIC TECHNIQUES OF MEASUREMENT

[摘要] This research focuses on patterns of change in the dimension stone commodity blocks quality production on previously identifi ed and measured geometrical parameters of natural cracks, modelling and planning out the fi nal dimension of stone products and fi nished products based on the proposed digital photogrammetric techniques. The optimal parameters of surveying are investigated and the infl uence of surveying distance to length and crack area is estimated. Rational technological parameters of dimension stone blocks production are taken into account.
