What is Controlled Blasting Techniques Overview about?

Controlled blasting techniques aim to reduce adverse impacts of blasting such as overbreak, ground vibrations, noise, and fractures in rock walls. Key techniques include line drilling, trim blasting, smooth blasting, pre-splitting, and using accurate electronic detonator timing systems. Signature hole blasting allows controlling vibration frequencies to minimize structural resonance through destructive waveform interference. Muffle blasting covers blast holes to arrest fly rocks near habitations.
