Development of methods and software algorithms for state forecast of the ultimate stressed rock massif

Abstract

Abstract The article covers a live scientific problem consisting in development of new and improving of existing digital technologies for forecasting a stress-strain state of ultimate stressed rock massif. The analysis of the researches has shown that the approaches based on the synthesis of mine monitoring methods and analytical forecasting methods are promising for assessing the state of ultimate stressed rocks. The existing hazard indicators can be beaded by the integral indicators of the stress-strain state of the rock massif determined with the help of geo-information systems. However, there are no methods, algorithms and software for figuring these indications. As a result of the research, methods of implementation and functions of software elements have been developed for determining integral indicators characterizing the state of an ultimate stressed rock massif. The “Methodological recommendations …” have been developed, which describes specificity of using the information system for forecast integral parameters of the rock massif stress-strain state and assessing the conditions for the rock destruction. The use of the designed methods, algorithms and software decreases geomechanical risks of gas-dynamic phenomenon occurrence, reduces cost of breakdown elimination and increases economical efficiency of the mining enterprises.
