Review of Blasting Operations of Summit Brick <br />2.0 ANALYSES of BLASTING IMPACTS <br />During detonation of explosive charges in rock, the available chemical energy is primarily used in <br />breaking and displacing the rockmass. However, some of the kinetic energy is released in the form <br />of vibration causing airborne noise, some concussion and strain waves, and possibly flying rock. <br />Injury to humans and animals or property damage may happen if uncontrolled. <br />In this section, AG evaluates all the potentially damaging e#fects that blasting might have on <br />people, animals and property on and near the Fox, Stocks, 8-MileClav, Beaver Creek, <br />Patton, Cedarwood, and Edmondson Mines. Also in this section, AG recommends specific <br />measures that can be employed to mitigate reviewed blasting impacts. <br />2.1 Impacts of Blast-Induced Ground Motion and Fracturing: <br />This purpose of this section is to evaluate the relative potential for all forms of damage that might <br />occur due to blast-induced ground motion or radial cracking. This section examines their effects on <br />neighboring property and utility lines and pipes. A short review of blast vibration dynamics is also <br />included at the beginning of the section to acquaint the reader with various ground motion <br />measures that are used in structural damage evaluations. <br />The following subsections analyze blast-motion impacts: <br />Section : ............................ Damage Concern <br />2.1-1 Structural Damage <br />2.1-2 Water-well Damage <br />2.1-3 Buried Utility Line Damage <br />Review and comments on the proposed blast control measures has been included. AG <br />recommends additional controls in some areas. <br />
