“…The proposed approach to the differentiation of ash of the coal in complex structural deposit (like the Elginskiy) and the developed methodology for the assessment of natural and technological dilution take into account the characteristics of coal formation, structure and forms of the inorganic substance found in coal, increased understanding of the mechanisms of fuel quality change from reserves to coal mining and coal enrichment flows [15]. The resulting estimates of the differences in the ash content of coal in the surface and subsurface parts of a number of seams provided the basis for justifying the need for their gross or selective processing to produce more homogeneous coal flows.…”

The article addresses the increasing complexity of mined or prospective coal deposits. The paper analyses the role of digital simulation in operation assessment and reassessment of the potential of complex in structure coal deposits for more accurate understanding their investment attractiveness, reliability of knowledge on quantity and quality of the reserves. The article stresses the objective need to take into account the realities of the VUKA-world, when companies have to react rapidly to changing of external conditions by adapting organizational and technological measures as much as possible to the constantly overestimated potential of the raw material base. It is of note that reserves should be assessed in accordance with international requirements in the light of the increasing number of parameters for management. The complexity of the structure, the geomechanical heterogeneity of the rock mass, the mineral content of the impurities in the coal, its caking capacity, oxidation and enrichment are taken into account in the estimation. The paper presents the measures to increase the level of utilization of geological potential through the application of selective mining and the control of different quality coal streams in preparation for enrichment and during primary processing.

“…On this basis, improvability of production-marketing chain from a mine to a consumer was revised. The approaches applied, results obtained and solutions proposed [10,16,17] are well embedded in the Digital Field concept and enhance efficiency of production and sales of coal additionally differentiated by the consumer properties. These are achieved by means of selective mining of coal in longwalls and extraction from coal pillars, separate dressing of coal with refined grade composition, reduction of coal loss in production and supply chains, as well as sound managerial and economic efforts aimed at cost saving.…”

Increasingly high uncertainty, complexity and variability of the mineral mining sector performance necessitates integration of digital technologies to improve business. Coal mines use DT much more less than the oil and gas industry. It seems a promising way to make use of the experience gained in the oil and gas industry to advance the Digital Field concept and Industry 4.0 as a basis for the sustainable tactical and strategic operation of business in coal mining. Digitalization of mineral resources and mineral reserves, geotechnologies and control provides a real-time picture of production and marketing. Furthermore, efficiency of coal exploration, mining, dressing and consumption is increased. It is expedient to use 3D modeling in evaluation of coal reserves, qualities and occurrence conditions to adapt mines to better and rival scenarios of development of structurally complex coal fields.

“…Most of the active sensing applications, infrared light sources are preferred for noncontact measuring duties in many studies [12][13][14]. There are also ultrasonic approaches for active sensing NDE methods using sound-based devices for quality control applications [15][16][17][18][19]. In one example, ultrasonic sources are used as sound-based devices for quality control applications [19].…”

Quality control is extremely important for manufacturing compatible parts to supply products that meet production requirements. It provides to track and control the stages of the process and minimizes waste by supporting high levels of productivity. Most of the manufacturers prefer a video measurement system (VMS), which offers non-contact high accurate measurement devices, for evaluating machined parts and products. However, due to the advanced technology and low competition the cost of the non-contact measurement devices is high. Besides some facilities and some research laboratories couldn’t reach these high-cost devices. Today, with the help of evolving technology and open-source image processing libraries, it is possible to offer cost-effective and accurate non-contact measurement systems. This study aims to put forward a VMS to measure parts/products in two dimensions with swift and accurate results. The proposed system has an error below 1% and the linear regression coefficient (r2) was found over 0.95. It works in real-time and minimum frequency was found 10 Hz for repetitive measurements, real-time measurement applications. The proposed cost-effective device can be adapted into various quality control applications in industrial manufacturing.
