Session Eight: Vibration Considerations for a New Aggregate Operation Next to a Dam (Room Lone Star DEF)

27 Jan 18
4:10 PM - 5:00 PM

Tracks: Blasters Training Seminar

Speaker(s): Geoffrey Rigsby

Technical challenges are often presented when proposing new blasting operations next to unique structures. This presentation will review techniques utilized for securing a new quarry permit next to a roller compacted concrete (RCC) gravity dam. There was a concern that the ground vibrations produced from rock blasting may induce excessive stress on the dam and deep concrete cut off wall. A study was conducted to measure the vibration effects on the structural integrity of these structures.
