... predicts compressional wave velocity better than the HF model. However, for Sv wave and Sh wave, HF model exhibited a better fit to the data at incident angles smaller than 30 degrees, while the LF Model provides better fits for incident angles greater than 70 degrees. Modeling the sample as an effective...

... laboratory corrosion studies have been undertaken to assess the metallurgical influence on SCC, the results do not correlate with field observations. A possible contributor to the enhanced incidence of premature failure in recent years may be due to the increase in extraction width from 250 m to 400m in many...

... mining geometry in terms which are significant to studies of rock failure. In this paper, it is shown empirically that the rate of energy release per unit area increase in the size of an excavation is closely related to seismicity and incidence of damage in the mine. Consequently, it is suggested...
