Sažetak
During the exploration and determination of natural stone deposits some important criteria should be analyzed. Colour and features
of ingredients define decoration criteria. The physical and
mechanical properties define technical criteria. Geological criteria
should be defined by geological characteristics, especially
discontinuities important for determination of exploitation and
stone block utilization from rock mass. Discontinuities restrict
the dimension (greatness) of the exploited stone blocks. Technological
criteria indicate the possibility and quality of cutting,
grinding and polishing of natural stone. All the stated criteria
influence the economical value of the stone.
The most important step during the exploration is measuring
discontinuities present in the body of the natural stone deposit.
In the present study a simple mathematical model is applied for
the spatial analysis of the discontinuities. The input data are α
and β angle (strike and dip of discontinuities). Detailed field exploration, old and new excavation banks and core drilling are very useful for determination of discontinuity, discontinuity density and discontinuity spatial relations. The results of examination,
as well as specific approach in particular deposits, should be utilized for evaluation of natural stone deposits.
