Our expert has also adv <br /> us that vibrations from our steady state operation will nor be perce <br /> at property boundaries. <br /> In order to assure that vibrations from blasting <br /> exceed ordinance levels, a variety of blasting techniques are custow <br /> utilized. Depending on the location of the shot within the pit and d <br /> ing on weather conditions, we can vary the number of holes shot, the <br /> of holes per delay, and the amount of powder per hole. <br /> Frequently we solicit the help and advice of other <br /> side explosive experts to guide us in loading and shooting in the saf( <br /> manner possible, and in a manner likely to restrict the noise and vib) <br /> to the lowest levels, possible. All state and federal blasting guideli <br /> are followed. <br /> 8.
