AVOIDING DAMAGE TO RESIDENCES FROM BLASTING VIBRATIONS

A PARTICLE VELOCITY OF 2 INCHES PER SECOND OF THE GROUND NEAR THE RESIDENCE IS THE MOST SUITABLE CRITERION FOR SAFE VIBRATION TO AVOID DAMAGE TO THE RESIDENCE WHEN BLASTING. A SCALED DISTANCE, WHICH IS DEFINED AS DISTANCE FROM THE BLAST TO THE POINT IN QUESTION IS FEET DIVIDED BY THE SQUARE ROOT OF THE MAXIMUM CHARGE PER DELAY IN POUNDS, CAN BE USED AS A GUIDE FOR DETERMINING THE AMOUNT OF EXPLOSIVES ALLOWABLE PER DELAY, A SCALED DISTANCE OF 50 FT/LB TO THE HALF POWER IS OFFERED AS A SAFE LIMIT IF NO SEISMIC INSTRUMENTATION IS USED TO MEASURE VIBRATION LEVELS FROM THE BLASTS. A SCALED DISTANCE LESS THAN 50 FT/LB TO THE HALF POWER MAY BE A SAFE LIMIT WHEN INSTRUMENTATION HAS BEEN USED TO ESTABLISH VIBRATION LEVELS.
