“…Frequency is used as a variable for geostatistical analysis; the fractal method has been applied for studying the fracture network [49,50]. Many studies focused on optimizing the exploitation planning based on multivariate geostatistical methods [51][52][53][54][55][56]. The results are used to generate a realistic 3D rock mass model which can be used in different applications, such as rock mass stability analysis, planning the exploitation system, or for sizing the exploitable blocks depending on the project goals [50,57].…”

The use of natural stone has historical and environmental value that makes it strategically valuable for landscape conservation in Europe. Marble, among others, is widely spread on Earth, and it offers high-performance features in architectural applications. However, the complexity of these formations and the rock variability in different ore bodies require detailed studies of the natural and induced stress state, the fracturing degree, and the influence of external factor (such as temperature and/or chemical agents) on the mechanical properties in order to optimize the exploitation processes by reducing extractive waste. This article shows a series of studies conducted by the authors over the last 20 years aimed at making the exploitation of marble blocks in the Carrara basin safer, more efficient, and, therefore, more sustainable. In particular, studies for increasing our knowledge of the natural and the induced stress state through on-site measurements and numerical modeling, studies to improve the quality of the exploited material through improvements of cutting technologies, studies to improve the knowledge of the mechanical behavior of the material under varying loads and temperature conditions, and studies to improve the reuse of water materials and their reduction are reported.

“…Paper [3] examined influence of natural fracturing on the productivity of technological complexes. It is worthwhile emphasizing a group of articles [4][5][6][7][8][9][10][11], the basic task of which was to assess blockiness of decorative stone deposits. This group of publications is characterized by the diversity of approaches to the definition of blockiness, in part due to different types of rocks that were examined.…”

“…Thus, papers [4,5] pay much attention to evaluation of blockiness based on the analysis of geometric ratios between the systems of cracks. The study of effect of fracturing on the quality of decorative stone deposit was the subject of articles [6][7][8][9][10][11]. Paper [6] examined the method of assessment of decorative stone deposit for obtaining block products based on results of fracturing measurement.…”

“…[8], based on the simulation of systems of cracks and splits, assessed deposit blockiness, the peculiarity being the use of cubes instead of the classic parallelepipeds for the model of an artificial block. The authors in [9] conducted geostatic simulation of the efficiency of extracting block stone at cutting, which substantially narrows the scope of application of results of this research, and requires further comprehensive consideration of influence of other technologies when planning development of mining. In paper [10], the estimation of economic efficiency of extracting blocks at different approaches to orientation of the front of work was performed.…”
