Blasting techniques used in Tunnels
The engineering concept behind Tunneling is always a matter of interest for Civil Engineering individuals. One of the most fascinating thought in general is the procedure of Blasting used for Tunneling. For some, it's just a regular practice however, in reality, it is as complex job in it's own. Today we will learn about Blasting techniques commonly followed during Tunneling works as well as in Mining activities depending upon various Engineering parameters. Blasting is an engineering practices used in mining and civil works for production of ores, surface, semi-surface, subsurface, and underground excavations, and demolishing of structures. It comes in several forms of blasting engineering as follows: - ResiBlast: Residential blasting with PPV = 2 - 9 mm/sec - CommBlast: Commercial blasting with PPV = 10 - 24 mm/sec - ...
