A NEW APPROACH TO THE DYNAMIC BREAKAGE OF ROCK

A NEW METHOD OF DYNAMIC BREAKAGE OF ROCK HAS BEEN DEVELOPED UTILIZING THE SECONDARY BREAKAGE EFFECT FROM AN ELECTRICAL PULSE PASSED THROUGH ELECTRODES INTO ROCK SPECIMENS. BREAKAGE WAS ACHIEVED FOR THE THREE ROCK TYPES TESTED. THE AMOUNT OF BREAKAGE WAS ANALYZED IN TERMS OF INCREASED SURFACE AREA USING A COMPUTERIZED STATISTICAL METHOD. FROM EXPERIMENTAL RESULTS AND A REVIEW OF AVAILABLE LITERATURE, IT SEEMS THAT THIS METHOD OF DYNAMIC BREAKAGE IS AT LEAST AS EFFICIENT AS CONVENTIONAL CHEMICAL BLASTING. /AUTHOR/
