The sleeve other end is connected through a screw thread, and the fixed disc is connected through a screw thread with the outer sleeve, and the chisel nail is bonded in institute
State fixed disc surface, can be fixed on blasthole surrounding rock surface, the stemming fixing device by guide pin, annulus base and
Retainer ring forms, the guide pin and annulus base one-piece casting, the retainer ring with guide pin by being adhesively fixed, the circle
Ring base is threadably secured with the fixed disc,
The telescopic device and stemming fixing device of described device are high-strength light plastic material.
Multiple-row blasting is carried out using above-mentioned multiple-row blasting device, is comprised the following steps：
1) powder charge is carried out after the completion of drilling；
2) detonator is installed, draws detonator lead；
3) stemming is loaded into blasthole fixing device；
4) stemming fixing device is stretched into blasthole, and the fixing device of outer sleeve front end is fixed at aperture；
5) electric rotating machine is opened, observation scale send stemming to precalculated position, and stemming is compacted under thrust；
6) reversion rotation motor, the inner sleeve for stretching into blasthole is taken out；
7) step 3,4,5 and 6 are back and forth completed, until completing the blocking of blasthole.
The beneficial effects of the utility model are：
The utility model is simple in structure, practical and convenient, improves stemming closure homework precision, improves blocking quality, reduce
Hand labor intensity, improves bridging efficiency, stemming accurately can be pushed to precalculated position by graduated scale so as to have
Effect ground control stemming length, makes stemming and hole wall close contact under the action of mechanical driving force, and the sealing performance of blocking improves,
Effectively extend and bombard action time of the gas in blasthole, improve the capacity usage ratio of explosive, improve demolition effect.
