Shamray O. Definition of mountain works' mode at the replaceable parameters and intensity of the sites base service of the iron-ore quarry.

The thesis has been devoted to the development of ways let rise mining efficiency by means of ore flows open-pit formation with the constant quality criterions. Technological diagrams of open-pit ore flows have been systematized for the first time and the yield of capital investments criterion application has been proved with their efficacy evaluation. The method of parameters assessment overload sites for the different ores sort on the operating intervals volume planning of its excavation has been improved. The improvement of ore flows dynamic control method in the open-pit by means of ore transportation separate diagrams from excavator dents have been proved. It lets to reduce the oscillation of the efficient component in ore raw material and ore transportation expenditures. Main research results have been taken into introduction by DPI "Kryvbasproekt" for the further iron ore deposit excavation designing. Estimated economic effect is about 495,6 ths hrv per year.
