Abstract

Analysis of scientific fields and practice of optimization of hydraulic mining process shows that, as a rule, there is no estimation of technological risks of usage of various hydromechanization complexes during the development of water-bearing sand deposits. In this case, technological risk means the threat of full or partial loss of hydraulic mining efficiency, as a result of influence of dynamic and static factors (parameters). Modeling of this risk is an event probability forecasting method, taking into account the influence of various factors. Risk estimation is a product of event probability and parameters of possible factors. Risks management reduces to the decision making before the problem rising, on the basis of modeling and estimation of risks. There are shown the researches and scientific and technical developments of methodology of mathematical modeling, estimation and management of technological risks during the water-bearing sands development with application of hydromechanized complexes. Dynamic and static factors, which make an influence on the efficiency of operations, are given along with ranking of these factors, according to criteria and efficiency. There are also given the mathematical model of calculation and estimation of risks, and system of development of possible risks.
