FIELD: mining industry.
SUBSTANCE: method includes performing preparatory mining, preparation of extracting column, driving of mounting chamber and mounting of mechanized system. During planning of shaft area extracting column is placed in such a way that geological disruption present on deposit was located near middle of extracting column. First, mounting chamber is driven near geological disruption on the side of lying side, disruption is opened and portion of column is extracted by mechanized system by straight drive. During these extracting operations and after primary caving of ceiling second mounting chamber is driven near geological disruption on the side of hanging side. After mounting of mechanized system in it and extraction of column by straight drive, disruption is opened and other portion of column is extracted by backward drive.
EFFECT: higher safety of primary ceiling caving.
