Abstract
The currently available blast vibration attenuation equations (AEs) usually only accurate for one-location database. The site specific parameters usually changes when the geological condition and blasting pattern changes. This paper is aimed to study the influence of geological condition upon the AE’s parameters K and β in Adaro coal mine, Indonesia. In order to achieve the research objective, blast vibration monitor devices, i.e. BlastMateIII®, were set up with respect to the geological condition and rock properties. During field monitoring, the blasting was not exclusively designed but was conducted along with the normal production blasting. The blasting experiment revealed that the peak particle velocity (PPV) values were in the range of 0.32 to 67.1 mm/s for scaled distance (SD) value 296.39 to 9.82 m/√kg. The frequency corresponding to the PPV values were in the range of 1.7 to 200 Hz, with dominant frequency in the range of 1.7 to 10 Hz. The provided database consisted of 182 data pairs from which PPV and SD values were analyzed and nine different AEs were produced. The experiments suggest that the parameters K and β of AE were strongly influenced by geological condition. Hence, an integrated blast vibration prediction approaches incorporating geological parameter into prediction formulae may produce an AE more adaptable to any changes in geological condition.
