Ontology of calculating the availability of mineral resources for solid minerals
Abstract. In modern conditions, the performance of prospectingand geological exploration becomes possible only after a thorough economic assessment. The ontology of a subject area is considered from the perspective of numerous researchers as a way of formally describing a given subject area, designed for an unambiguous interpretation of terms within its limits. In relation to the sphere of subsurface use, the creation of an ontology is especially relevant due to the significant amount of accumulated information resources. When conducting geological exploration, prospectingand exploration of the subsurface, it is necessary to rely on the existing basis of geological knowledge of a territory. In the process of performing an economic assessment on solid minerals, it is necessary to take into account the indicators of annual productivity in extraction and processing, losses, dilution, etc. These indicators affect both the current state of reserves in terms of the dynamics of their repayment, and the need for geological exploration in terms of the prompt elimination of the resultingshortage. At the same time, some indicators, such as the dimension of the object, the complexity of its development, the consumer properties of raw materials, and its natural quality, have a pronounced qualitative component in the evaluation process, which determines the need to involve experts. That is why the construction of an ontological model will make it possible to consolidate both quantitative and qualitative characteristics of the research object within a single structure. In this paper, an attempt is made to determine the availability of exploited raw materials using an abstract array of data on the available geological study of the territory using an ontological model.
Keywords: ontology, mineral resource complex, solid minerals, economic efficiency assessment.
Highlights:
- the economic assessment of mineral resources for solid minerals includes a number of quantitative and qualitative indicators that are quite difficult to combine into a single system, consolidate in calculations, and then compare several promising objects with each other;
- consolidation of clear (quantitative) and fuzzy (qualitative, expert) assessments is necessary in the field of subsurface use due to the need to dynamically assess the availability of reserves by types of raw materials and by certain taxonomic units (from the territory of a locality to the territory of an entire region);
- for the purposes of calculating the availability of raw materials, quantitative indicators include indicators of annual productivity in extraction and processing, losses, dilution, etc., qualitative indicators include, in relation to the object of research, the dimension of the object, the complexity of its development, the consumer properties of raw materials, and its natural quality.
