Reduction Measures of Blast Vibration on Adit Passes at Lanjian Iron-ore Pit
The influence of blast vibration gives prominence to a safety of adit passes when bench mining is going down. After theoretical analysis and field tests hole-to-hole millisecond (MS) delay blasting, two-in-hole MS delay blasting, two-in-hole and hole-to-hole MS delay combined blasting have been practiced to reduce blast vibration. The effect of reduction measures is obvious and adit passes have been protected efficiently.
