CRITERIA FOR THE CONTROL OF VIBRATIONS CAUSED BY THE USE OF EXPLOSIVES IN ROCK EXCAVATION

CRITERI DI CONTROLLO DELLE VIBRAZIONI PROVOCATE DALL'USO DI ESPLOSIVI NELLO SCAVO IN ROCCIA

This paper first identifies the characteristics of the vibration phenomena induced by an explosion. It then defines the magnitude of vibrations which a given structure could withstand without risk of damage; the dynamic stress levels of a given structure; the characteristics of the pull, with reference to the type and quantity of explosive and the delay between the various changes of the same pull; and the vibration control systems indispensable to a proper operation. The physical laws controlling the risk of damage (safety index) are analysed, and a numerical evaluation of risk level is presented. Finally, some existing standards in France, Switzerland, East and West Germany, are examined. (TRRL)
