| description | The invention discloses a directional hydraulic type rock breaking device and method. The rock breaking device comprises an ultrahigh pressure pump station, an ultrahigh pressure liquid inlet pipe, anultrahigh pressure liquid return pipe, a fracturing jack assembly, a jack push rod, an instrument panel, an instrument panel connecting pipe and an oil filter assembly, wherein the ultrahigh pressureliquid inlet pipe and the ultrahigh pressure liquid return pipe are connected to the outer side of the ultrahigh pressure pump station. The directional hydraulic type rock breaking device and methodcan solve the problems that coal mine production needs to adopt the way of blasting to deal with high ground stress and large deformation roadways, rock burst and gas extraction, and some difficult problems such as difficult control of charge quantity and difficult avoidance of blind gun are also solved when the ground quarry and cutting mountain are treated by blasting; the hydraulic rock breaking device can realize that d |
