MEASUREMENT AND EVALUATION OF BLASTING GROUND

ground motions resulting from the blast, and the movement of rock at the bench face. Audible air blast is called noise while air blasts at frequencies below 20 Hz and inaudible to the human ear are called concussions. This is measured and reported as an “overpressure” it means air pressure over and above atmospheric pressure. The noise

Ground vibration: Air blast Introduction On surface mining, blasting technique may be considered as the most economical method used for fragmenting rocks masses. Nonetheless, only 20-30% of the used energy is served for rocks fragmenting and displacing, while the rest is wasted in the form of ground vibration, air blast, noise and fly-rocks [1].

Ground vibration and airblast is noticeable at levels far below those required to produce any cracking. Perceptibility of ground vibrations starts at about 0.06 in/s and is noticeable from house rattling at about 0.03 in/s. An airblast of 110-115 dB will create audible structure response even if the direct airblast (sound) is not noticeable.
