The beneficial effects of the utility model are：
1. using pack diameter be less than blasthole diameter, make to form cavity between pack and blasthole, at the same use two with
Upper pack realizes the Discontinuous charge mode in blasthole, and when explosion, the shock wave that pack generates passes through the air borne in cavity
Into hole wall concrete, the air gap effect is similar to air cushion, and the gas energy buffer storage of explosion starting stage is got up, is cut
The release of the gas energy of storage is done in the weak initial pressure peak for acting on blasthole, then be further the hit impact of wave of gas
Work(extends the time of detonation gas product effect, buffers the pressure that simultaneously balanced explosion generates, improves demolition effect.
2. fixing pack in advance using bamboo chip, pack neglected loading, few dress or more dresses are prevented, bamboo chip, blasthole and big gun are utilized
The cooperation of mud realizes the fixed point installation of pack, realizes being precisely controlled for fire point.
3. pack is equally distributed in bamboo chip surface, being uniformly distributed for fire point is realized, ensure shock wave energy in blown-out shot
Equiblibrium mass distribution in hole avoids same blasthole shock wave from being unevenly distributed, influences the collapse direction of shear wall.
4. the distance of two adjacent shot hole central axes is equal to the thickness of shear wall, the same blasthole four sides up and down
The detonation energy that position generates is uniformly distributed.
