Özet
The geometrical design of optimum cutting is the first task in natural stone quarries. The largest trade blocks (quboits) are the most desired, but they are limited by several geological drawbacks, including one of the most important, discontinuities in rock mass. Rock blocks in mass that formed naturally may range from very small to a few meters with different shapes and orientations. Most trade blocks are chosen and cut from intact rock that bounded discontinuities. Therefore, a discontinuity-based economical analysis should be done in many phases, especially in pre-evaluating deposits and during the cutting operations. There are many modelling methods related to discontinuities. These methods have been used successfully as one of the main tools in many mining and civil engineering applications such as stability, blasting, and fluid flow. Nevertheless, discontinuity-based assessments and economical analyses related to them have not adequately progressed in the natural stone industry. The analyses and assessments in natural stone quarries generally are still done with human perception. Furthermore, it causes the loss of a large amount of natural resources as an inevitable result of low technology. The general aim of this study is to compare the current and optimal conditions of productions in active dimension stone quarries as well as pre-evaluations of natural stone deposits. Therefore, we suggested a new perspective comparing the distribution curves of blocks (polyhedrals and quboits) from in in-situ deposit to the final product. This paper also made several theoretical comments about distribution curves.
