Despite considerable advancement of information technologies in the area of mining, the attempts of the modern researchers to create a single universal mathematical model to describe geomechanical processes in rock mass have failed to produce any notable result. It is found that a mathematical model capable to solve wider class of problems exhibits limited abilities in solving individual applied problems. The causes of that are, on the on hand, insolvability of a problem within a universal model endeavoring to cover all characteristics of rocks, and, on the other hand, aliasing of objectives of the modeling (for instance, some problems require stability of preset rock mass areas, while the other problems assign failure in these areas). For this reason, the prevailing trend of mathematical modeling in geomechanics is solution of individual applied problems. Under such circumstances, many theories on mathematical modeling of geomechanical processes in rock mass have appeared. Currently, the researchers have accumulated ample knowledge on the efficiency of such problems in different problem solving. Unfortunately, the knowledge is disembodied, inexplicit and unformalized. At the same time, the use of such knowledge will allow researchers to greatly reduce labor content of mathematical modeling. Aimed at fixing this problem of current concern, this article describes an expert system for selecting a theory to be most suitable for development of an adequate mathematical model of geomechanical processes in rock mass with regard for the applied problem to be solved. The architecture of the expert system consists of the graphical user interface and two subsystems. The first subsystem of the intelligent database control is for editing, addition and elimination of production rules. The second subsystem realizes the inferential mechanism to administer progress of the problem solution on selection of a desired theory to construct an adequate mathematical model of geomechanical processes in rock mass.
