Abstract
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.
Highlights
Development of coal deposits often takes place in extreme climatic and geological conditions [1, 2]
The analysis shows that the theory and practice of prospecting, simulation, estimating and refining reserves generally do not fully take into account all the important and minor features of the mineral raw material base, the ever-increasing potential of digital technologies for comprehensive assessment and rapid reassessment [3, 5,6,7,8]
Detail, the preparation of a number of decisions aimed at increasing the level of realization of the potential of the coal reserves of a number of coal deposits laid down by nature
Summary
Development of coal deposits often takes place in extreme climatic and geological conditions [1, 2]. Capacities and angles of incidence, the presence of different brands and grades of coal within the same seam, block; high variability and non-additivity of consumables of raw materials in reserves; cluster distribution of useful and harmful components; other natural and technological factors The consequence of this situation is the inevitable complication and rise in cost of all processes of long-term and multi-stage development of deposits. An increase in the level of scientific and practical substantiation of the opinions and conclusions of experts can be achieved on the basis of the maximum possible understanding in terms of completeness and accuracy at the current time of all visible and hidden features and capabilities of the fields themselves, as well as various business initiatives implemented during their development In such a situation, the improvement of work on a technologically efficient, economically viable and environmentally acceptable level of development of coal deposits should be carried out taking into account the following approaches [4]. This, in turn, necessitates a more detailed consideration of the situation described
