The document discusses blasting operations carried out at the Ramagundam Thermal Power Station in India to excavate rock as part of an expansion project. Blasting was required near sensitive existing infrastructure like generators and transformers. Careful planning was needed to limit ground vibrations and prevent flyrock. Through trial blasts, parameters were established for burden, spacing, stemming, and initiation timing. Blasting progressed from areas farther from critical infrastructure toward them. Methods like changing blast direction and using soil and covering mats helped restrict flyrock and vibrations near the edge of blasts closest to generators. Blasting for footings also required high stemming and covering density to minimize flyrock risks to nearby structures. The successful blasts achieved required
