Typical Blasting Methods for Structural Engineering

Blasting technology is an essential part of the construction process to perform structural engineering activities. Blasting is the process of cracking rock material by using a small amount of explosive substance so that the rock is destroyed into several pieces. In the past, black powder and dynamite were used for the explosive process.
