Nov 30, 2010· The profitable production of dimension stone mainly depends on the extractable block size. The regularity and volume of the blocks are of critical importance, and are controlled by the threedimensional pattern of the discontinuity system. Therefore, optimization of block size has to be the aim when quarrying for natural stone.

Dimension stone can be defined as natural rock material quarried for the purpose of obtaining blocks or slabs that meet specifications as to size (width, length, and thickness) and shape. Color, grain texture and pattern, and surface finish of the stone are normal requirements.
Similarly, mining methods themselves generally have a low impact on the surrounding environment due to the need to carefully extract large blocks or slabs without damage to the stone [1]. Recent advances in dimension stone mining technology have also had the effect of reducing environmental impacts [5].
