In the article, the author presents his findings on improving the tested and well-proven in practice information system used for calculating stress-strain state of rocks and assessing stability of workings. This digital system is used as one of the main elements for forecasting risks and ensuring safety of the mining operations. Purpose of the research: to improve methods for organizing computational processes and to build software models of the initial data automated preparation and analysis of the results of solving the complex problems on the rock massif and mine working stability. The research showed that in this program, calculation time became shorter with increase of centripetal chaining of interconnected groups of classes and became longer with increase of their abstractness. This effect allowed obtaining a well-balanced software package through the minimization of total deviations of the Martin metrics instability and abstractness for all groups of the information system classes. These new solutions laid the basis for the information system developed for supporting making of the decisions on the mine safety. A new system was developed for inputting initial information and for displaying and analyzing results of solving the complex problems of geomechanical stability. The designed digital system for the rock massif stress-strain state forecasting features some advantages and is distinguished by the following functions: interactive control of the design schemes; ability to automatically split domains under the study; differentiated separation of value ranges; editor of physical and mechanical properties of rocks; functions for calculation of basic and integral parameters for the medium, as well as ability to compare of the control object states. Besides, algorithms for calculating 16 types of automatic model discretization, given forces and displacements, node coordinates, angles of bed dip were built and implemented. This digital system for the rock massif stress-strain state forecasting is used for supporting making of decisions by assessing stability of the rock massif and mine workings.
