Abstract:
      The blasting into joint principle of presplit blasting technology and application in the engineering construction are discussed briefly in this paper, and taking the open-pit mine as an example, and the paper expounds the pre-splitting blasting technology which play an important role in protecting slopeSstability, at the same time the representative of the problems which often occur in the process of Pre-splitting blasting construction have been discussed, then the corresponding solution method is put forward. The study will play a role of guidance and reference for similar construction.
