In Mengzi beltway freeway blasting earthwork construction,through the use of hole- by- hole blastinginitiation technique it controlled block-degree at 10%,the maximum blasting vibration velocity at 0.2 cm/s or less,blasting clocked at 10-50 Hz. And it successfully solved the problems such as serious vibration,blasting flyingstone and big block in the complex environment when using the traditional method of blasting. The hole-by-holeblasting technique in our study achieved good blasting effect.
