SEMANTIC INTERPRETATION OF FUNCTIONAL-FACTORY MODELS OF GEOMECHANICAL PHENOMENA

Abstract

The paper concerns the methodology of construction and semantic interpretation of functional-factorial models of experimentally observed geomechanical phenomena in mining. The methodology includes the structure of modeling and methods of semantic interpretation of the two-dimensional models most in demand in scientific research, calculated by the computer program "FSP-1 Trends" and containing one or two power or exponential functions associated with a constant component or an oblique asymptote. In the methods of semantic interpretation of models, the influence of causal factors is taken into account – the influencing circumstances and processes of the geomechanical phenomenon, leading, with the growth of the argument, to the rise or fall of its dependent value. The features of such changes are expressed by the model parameters of the functions, which give a specific idea – how steep or flat and how many times they increase or decrease with the growth of the argument by a specified interval. The description of changes in the dependent value formulated in this way, characterized by the influence of causal factors, functional parameters and coefficients, is the essence of the discovered new knowledge about the phenomenon under study. As an illustration of the semantic interpretation of the models, five practical examples of experimental geomechanical studies are given. The examples show that this methodology achieves their main goal – to establish and explain the patterns of formation and development of the observed phenomenon. The semantic interpretation of the model, formulated by analogy with the examples given, can constitute a defended scientific position in dissertation research.
