Abstract
The scientific article gives an investigation of technological solutions for intensity the ore drawing, which will improve the completeness of extraction of freed ore and the quality of ore mass. As a result, it has been established that one of the key solutions to this problem is the use of a combined method for the delivery of ore and ore mass with the help of the “multi-bucket scraper winches – self-propelled loading and unloading machine” complex. Since the application of this complex is most adapted to the complex geomechanical conditions of the deep horizons of the Kryvbas mines. Research and technological solutions for decreasing the amount of localization of ore mass hanging in the draw-points upto 1,4–2,2% are presented, which will allow increasing the operational productivity of the scraper winch up to 600–700 tons/shift. And it will also make it possible to increase the intensity of the technological process of ore drawing from 1,5 to 5,5–6,2 tons/m2 per day and the extraction of clean ore to 10,5%.
