Kalinichenko O. Estimation of economic results of iron-ore production taking into account influence of geomechanical risks.

Dissertation is devoted to the development of tools and practical recommendations in relation to the complex estimation of economic results of iron-ore production taking into account influence of geomechanical risks at development of iron-stones by open-pit method. In the dissertation the essence of concept of complex estimation of economic results of iron-ore production taking into account influence of geomechanical risks and present economic methods of their influence is specified by efficiency of production. The economic mechanism of analysis, estimation, optimization and management present risks is developed. Investigational scientific directions of estimation of economic results of iron-ore production on the basis of application of complex criterion of the forecast probability of obtaining of a maximum income, which is determined as a difference between an economic effect, received due to diminishing of charges of mining at the increase of slope angle of a wall of iron-ore pit and by the forecast size of possible economic losses taking into account probability of origin of geomechanical risks. An actual economic effect from introduction of dissertation results on OJSC "Ingulets mining and concentrating complex" performance made 105,86 thousand UAH. Sector - the economy (mining).
