Cluster analysis of fracturing in the deposits of decorative stone for the optimization of the process of quality control of block raw material

Abstract

When developing the deposits of decorative facing stone, the economic efficiency of mining to a large extent will depend on the effectiveness of management of technological processes. According to the results of research into approaches to the process of extraction of blocks of decorative stone [1-8], the efficiency of application of separate 19.

The New Approach of Using Image and Range Based Methods for Quality Control of Dimension Stone

“…Sobolevskyi has investigated relationship between the number of cracks in the rock mass and their spatial orientation for selection the direction of mining development (Sobolevskyi et al, 2016).…”

Exploring the efficiency of applying fractal analysis for the process of decorative stone quality control

“…After summarizing the outcomes of the studies, which were implemented in articles [1][2][3][4][5][6][7][8][9][10][11], it is possible to distinguish the following parameters that can be used for quality control of the blocking products: geostructural (orientation of fracturing, linear dimensions of cracks, depth of cracks location, shape of natural separatenesses, blockiness) and technological (anisotropy of deposit properties, orientation of monoliths in relation to the faces of the natural separatenesses, the speed of drilling and diamond rope cutting of a fractured array).…”

“…The image taking parameters: camera Canon PowerShot G12; focal distance 25 mm; 4.34375 lumens; diaphragm 4.5; shutter speed 1/250 s. In the obtained image, we distinguished cracks by ImageJ 1. 47 v on the basis of using approaches to recognition and identification of cracks, described in papers [1,7]. The section with identified cracks was evenly divided into zones.…”

“…Different methods of mathematical processing are used in studying fracturing, among which the methods of cluster and fractal analysis can currently be considered as the most promising. The methods of cluster analysis, applied in previous studies [1,2], revealed low effectiveness in the cases of generalization of results of fracturing measurements at different structural levels. Results of research of various authors prove the fractal properties of fracturing at different structural levels, which makes exploring the fractal nature of fracturing and using the obtained regularities for controlling the technological processes in mining natural decorative stones a relevant scientific and applied task.…”

“…We live in a period of wide scale implementation of computer systems and intelligent technologies in all spheres of human life, one of which is the Smart City system [1][2][3][4]. Smart City is a complex system designed to provide upto-date quality of life of residents through the use of new technologies, which involve economic and ecological use of the urban subsystems of life activity.…”
