Blasthole directional fracture apparatus

The utility model discloses a blasthole directional fracture apparatus. The apparatus comprises a first side pipe wall and a second side pipe wall, wherein groove connecting clamp blocks are arranged on the surfaces of the first side pipe wall and the second side pipe wall, a detonating cord is arranged in the center of the first side pipe wall and the second side pipe wall, and both two ends of the detonating cord are provided with energy concentrating grooves. According to the abovementioned technical scheme, V-shaped grooves are formed at two sides of an explosive contained in the blasthole direction fracture apparatus when the apparatus is placed in a blasthole, the central detonating cord simultaneously makes the explosive contained in the apparatus be detonated from the center, the explosion is then transferred to two sides, the explosion transferring direction is altered locally at the energy concentrating grooves, and energy concentrating faces are formed, thus to form huge detonation energies on the planes of the grooves, achieve direction cutting, and reduce damages to preserved rock mass parts; and the apparatus is two meters long, so directional cutting holes of different lengths can be formed through free combination of the apparatuses, and the blasthole directional fracture apparatus is superior in practical performance, flexible in usage and novel in design, is an excellent innovation scheme, and has a good market promotion prospect.
