| Abstract: | Dagushan's iron mine whose iron ore is in its third fragmentation system is in the construction process,in which the vertical deep-hole blasting technology was adopted to excavate the fragment room.This technology makes the work-time far shorter than before.In the process of blasting design and construction,short delay pre-splitting blasting technology among and inside the holes is used successfully,and a better technique economy effect was obtained.This technology has provieded some valuable references for the domestic similar engineering blasting. |
