Non-explosive (spare) technology of charoit extraction on the base of usage the special composition of powder and wedgedestroying device for charoit block separation from massif has been developed, tested and recommended in order to preserve new semi-precious stone — charoit. Deposit of charoit was founded at the border of Yakutia and the Irkutsk Region. Great advantages of proposal technology have been substantiated in comparison with conventional borer-wedge method.
