Abstract
The author addresses a method of creating directional conjugated fractures in a solid medium, integrating features of interaction of fractures and holes, specifics of fracturing by plastic materials and the use of holes as the front guides and limiters of created fractures. This method can be used to enhance efficiency of open pit and underground mining, as well as for creation of closed impermeable envelopes for advancement of slot mining technologies without construction of underground mines.
