Oriented flexible rock breaking device and method

The invention discloses an oriented flexible rock breaking device and method. The device comprises a high-pressure water injecting pump, a main high-pressure connecting pipe, a connecting tee joint, an expandable high-pressure hose, a digital display pressure gauge, a rigid high-pressure connecting rod, a pushing structure, high-frequency vibration structures and a pressure continuous recorder; the high-frequency vibration structure are fixed on the two sides of the pushing structure to solve the difficulties of treatment of high-crustal stress and large-deformation roadways by a blasting modein coal mine production, rock burst and gas extraction and the difficulties of difficult control of the explosive payload and difficult prevention of blind shells in treatment of ground quarries andcutting mountain bodies by the blasting mode; flexible fracturing pipes are lighter to realize synchronous fracturing of the whole holes; through synchronous row fracturing of multiple holes, the oriented rock rupture can be r
