Article Preview

Blasting vibration damage is a major factor in mine safety. Millisecond blasting is an effective means to reduce blasting vibration damage. Taking field test method to study high slope deformation in open pit mines a little bit difference of each quick-fried bore blows up’s blasting vibration damage. Research found that, taking a little bit difference of each quick-fried bore blows up, Slope’s vibration velocity is 0.6cm/s, Compared to initiation by row’s theoretical value reduced by 58.33% , a little bit difference of each quick-fried bore blows up is an effective means to reduce blasting vibration damage, it is great significance for improving the slope stability.
