| Abstract: | In stripping work in Daxigou Iron Ore Mine, the conditions for blasting are unfavorable. Under these conditions, the work of optimizing explosive chamber, selection of blasting parameters and determining of detonation sequence of multi-stages short delay blasting has been done. Thus, an 1.22 Mm^1 volume blasting with a throwing rate of 57% is successfully realized by which the flying stones, vibration harm and impacting area are well limited. |
