摘要：
The article presents the results of industrial-experimental tests of technology for extraction of open-pit border and bottom reserves of copper sulphide ores under different conditions at ore mines of OJSC "Uchalinsk MDK". Description is given to the technology of extraction of border reserves at the Sibay underground ore mine with the use of the open chamber with ore discharge through underground workings, as well as to the order of ore reserves extraction at the Uchalinsk underground ore mine.
