Ten Year US Eleven State Study of Blasting Damage Claims

An engineering study of 2,250 blasting damage claims from 1999 to 2008 in Tennessee, Kentucky, Virginia, Nevada, California, Georgia, South Carolina, North Carolina, Alabama, Arizona and Utah were investigated over the last decade and these investigations determine that blasting ground vibrations damage claims are valid less than 1.3 percent of the time. This study determined that valid blasting damage occurred as a result of impact damage associated with fly rock, air concussion stressing, instantaneous reverse stressing associated with ground vibration and crater zone soil shifting related stressing.
