Method of mine geometry for evaluation of separate block categories reserves on decorative stone deposits and its application in the field ?Syuskyuyansaari?

摘要

On a natural stone quarry both reserves evaluation and planning are closely connected with the identification of the open-pit field partition into blocks by natural cracks because the value of its production depends on the size of the blocks. The distribution of natural units by categories, so-called "blockness", is the most important characteristic of reserves.
