It has many advantages. Firstly, it requires less preparation work and can complete a large amount of rock blasting in a short period. It is suitable for rocks of various hardness, especially in complex terrain areas like dams, where it is not restricted by construction conditions. Moreover, it does not require special drilling equipment; a drilling machine can generally be used for excavation, and anything used for deep-hole blasting can be used in chamber blasting.
Most importantly: the volume of a single blast is large, reducing the number of blasts and the time spent avoiding blasts!
In other words, once the loading is completed, a single successful blast can be carried out, significantly saving operational time.
The more time saved, the more time the reservoir has to release the flood, making the public safer!
