Iskov S. Geometrization of qualitative characteristic of deposits of decorative granite and gabbro stone.

Dissertation is devoted to the questions of geometrical analysis of changes in qualitative characteristic of hard decorative stone using the program applied batch. In the result of investigation and using modern GIS the dependence of the change of layered inter-fracture lengths on the intrusion surface and the influence of changed rock intensity on its main decorative characteristics are determined. The method of anisotropy natural stone determination and the method of optimal direction determination of mining works relative to natural fracture of massif and classification of deposits on technological zones are worked out. On the basis of theoretical and experimental investigations it was proved the ability to obtain complex plans of quantitative expressions of qualitative characteristics of deposits and stones by means of mining geometrical analysis of these main characteristics using modern computer-information technologies and GIS. Obtained results can be used for mining field division on technological zones depending on geometrical characteristics of fracturing, blockiness, decorativeness, irrization and rock changes so as designing of rational device complexes for each of these zones. It helps to optimize blocks extraction from massif and to increase the quality of extracted raw material; to lessen losses and to improve engineering-economic characteristic of production.
