One of the methods used in blasting operations in open pit mines is air deck method. An air gap in the explosive column known as an air deck has been applied in surface blasting as a means to reduce explosive charge, vibration, fly rock, and improve fragmentation and controlled blasting in some situations. We designed and manufactured AB plug as an Airdeck and Stemming plug. It is used in pen pit and underground blasting operations. AB plug can be used can be used at any depth for multilevel blasting.
Safety, More control of the blast, Less ground vibration, Less airblast, Less fly rock andrifling, Less Backbreak, Increased high wall stability, DRILL & BLAST, Minimization or elimination of sub- &...drilling, Lower explosives consumption
1) Drilling and blasting operations in open pit mines.
2) Underground horizontal hole blasting.
