Information technologies of geomechanical events integrated simulation

Introduction. Neither national nor foreign practice can guarantee high-quality assessment of enclosing rock mass state and reliable substantiation of rational geomechanical solutions. It is confirmed by actual accident and breakdown rates including catastrophic force majeure. So, current methods of geomechanical analysis need principal improvement. Research aim is to develop information technologies of integrated deterministic stochastic modeling within the system of assessing and ensuring the quality of geomechanical solutions, which is the set of interconnected estimates and indicators, such as efficient, available, reliable and adequate information on enclosing rock mass properties and state, compliance with the requirements of normative documents, geomechanical risks rates by the factors of breakdown, accident and environmental hazard factors, potential damage from risk aftermath, financial receipts and expenses which include dominant functions of potential damage and monitoring effectiveness. Methodology. Research has been carried out based on the simulation builder, basic software aimed at design, checkout and probation of new integrated deterministically stochastic models of geomechanical events. The models fulfill research, training and demonstration functions, reserve modeling process and output, simulation errors and drawbacks elimination by Monte Carlo method. The main feature of the builder is the availability of interconnected components, determination and simulation. Such complex provides the researcher with important complementary information: deterministic method fulfills safety functions and determines analysis results non-contradiction to the requirements of normative documentation; probabilistic method ensures objective evaluation of geomechanical risks or safe features with the possibility to obtain clear effectiveness by the factors of economic and social security, eliminates or significantly reduces the probability of unnecessary expenses. The universality of the approach to creating information technologies of geomechanical solutions simulation which implement the deterministic simulation complex based on the methods of nonparametric statistics is confirmed by the instances of simulation in multivariate statement. The scope of the investigation includes mine engineering structures of construction, open, integrated technologies of mining enterprises and specific underground development targets in various sectors of national economy. Summary. Information technologies of geomechanical events simulation based on the complex of deterministic and simulation methods and the procedures of nonparametric microstatistics make decisive contribution in the system of assessment and ensuring the quality of geomechanical solutions. The universality of IT development is noted together with their availability for a wide range of users, their simplicity and implementation efficiency
