The analysis of factors is fulfilled, which determine degradation of rock massifs breaking process with the cutters of heading machines and winning machines. It is indicated that the most frequent reason for rock-breaking tool of continuous miners’ failure is abrasive wear of the holder’s head and the loss of the hard alloy insert as the result of the action of significant side loads on the cutters holders. The construction and the principle of action are described for the cutter mounting device in the executive device of a continuous miner, which provides automated self-adjustment of the
cutter support body with the cutter in the process of rock massif breaking; this allows cutting without deviation along all the lines of the designed breaking scheme. Suggested engineering solutions provide the decline in the massif breaking process energy capacity and heading and winning machines cutters service life increase.

Key words: cutter; cutter holder; automated self-adjustment; continuous miner; executive device; cutting efficiency improvement; operating hours increase.
