Abstract:

In view of the technical puzzle of the blast in the solid rock mass and the rock conditions on site,the blast scheme design has been conducted and the preliminary test has been done on the basis of the theoretical calculation.The blast efficiency is raised nearly once and the result which can be adopted in the similar rock mass is idealer.

Key words: Solid rock, Cutting method, Blast2gike ytukuzation ratio
