ABSTRACT
The grouping of granite areas in Zhytomyr region was made on the
basis of cluster analysis. It was determined the character of interconnection among
structure indexes of granite deposits and received analytical dependence for measuring deposit’s size. The analysis of fracture systems using different methods of clustering was made. It was grounded that the maximum clustering efficiency was characteristic for К-means (Chebychev Distances) method. The fracture systems were allocated and their parameters were defined. Basing on the defined system of fractures and the previous results of assessing dependence of the energy efficiency of ruining granites depending on the separation surface, it was grounded the optimal direction of mining works development. The cluster analysis of distances between the layer cracks for determining the rational height of the quarry ledge was made. The rational direction of mining operations, that would coincide with the orientation of the lengthwise system of fractures and would comprise 70,00000о 8,16497о was substantiated. Using the cluster analysis for high-altitude localization of fractures of natural separation allowed giving the proofs to the altitude of terraces for different horizons. It was proved the efficiency of applying cluster analysis for determining optimal parameters for the system of granite deposits development.

Keywords: cluster analysis, granite areas, fracture systems, rational direction of mining operations, parameters of mining system.
