Sobko B. Scientific a substantiation of technology of open-cast mining of the titanium-zirconium alluvial deposits of Ukraine

Thesis is devoted to a scientific substantiation and creation of effective tech-nology of open-cast mining of the titanium-zirconium alluvial deposits. In work the dissect of a modern condition and prospect of open-cast mining of the titanium-zirconium alluvial deposits of Ukraine. The developed classification alluvial deposits of Ukraine. The developed concept and scientific principles of open-cast mining of the titanium-zirconium alluvial deposits are offered. Use of a parameter of concentration of mining works in quarry which is recommended for applying to an estimation and a choice of effective systems of development alluvial horizontal deposits is proved. The mathematical model of process of formation of a working zone quarry is developed at development of horizontal deposits which allows to consider parameters of system of development of a deposit in view of parameters of a working zone quarry, its capacity, and also productivity of the basic mining-transport the equipment. Techniques of a choice of the rational technological scheme exposure and produce works, mine technical parameters of selective development of alluvial are developed. Modern methods of increase of efficiency of open-cast mining alluvial deposits are offered by application of digital plans of district and three-dimensional geological models for the decision of mining-technological problems, satellite radionavigating systems for increase of an overall performance mining-transport the equipment in the quarry.
