Abstract
The size and shape of natural stone parts, that are defining the rock jointings, are also affecting mining technology and field of operations. Besides, it influences monolith optimal cutting scheme for commercial dimension stone blocks, corresponds to required geometrical dimensions. Prediction and selection of rational ways of cutting structural blocks is really important issue, because stone losses depend on the cutting pattern and also further inaccuracies in measuring the size of commercial blocks due to different factors. The main problem in this field is improving the accuracy of measuring the size of block at the dimension stone quarries which is based on the simulation of natural individualities and the introduction of indirect methods for determining the qualitative and quantitative characteristics of commercial blocks. The main factors that can cause the accuracy of determining the commercial blocks volumes under traditional methods of their calculation are also considered in this work. The authors analyzed the main indexes of the commercial block passport, as well as the possibility of adjusting the individual technological parameters for the separation of monoliths into blocks. Classification of block products is proposed for classes depending on qualitative indicators. Possible models of the formation of the basic parameters when separating the monolith on commercial blocks are considered, as well as the formed cost component for the possibility of rapid accounting in mining enterprises.
