Abstract
The present invention aims at estimating a residual life of a blasting vessel. For the estimation, a strain gauge 30 is attached to a blasting vessel 10. The strain gauge 30 measures high-frequency repetitive strain caused in the blasting chamber 10 in each explosion. Strain waveform data obtained with the strain gauge 30 is analyzed to calculate the cumulative degree of fatigue damage due to a high-frequency repetitive load applied to the blasting vessel 10 in each explosion. A residual life of the blasting vessel 10 is estimated on the basis of a cumulative value of the cumulative degrees of fatigue damage.
