| 摘 要： | 这项研究探讨了岩石在0～500Hz范围内的声学振动频谱,在不稳定顶板岩层中,这种声功率谱在频率为200～1000Hz范围内有特征性的增高,而这种效应在3000～5000z频带范围内则没有,这种特性为测量岩层稳定性提供了一种有效的方法.

| Abstract: | This study examines the acoustic vibration spectra of rocks in the range of 0 to 5. 000 Hz. This power spectra of socalled drummy rocks were found to be diagnosti-cally enhanced in the range of 200 to 1,000 Hz. Comparison of the power in this band with that in a band from 3, 000 to 5,000 Hz. provides a quantitative measure of rock stability. |
