| 摘 要： | 为了查明岩石压入硬度与声发射参数如累计信号数、总能量、峰值RMS(信号均方根值)、积分RMS等之间的关系,在9种不同的岩石中进行了压入试验。结果表明:岩石压入硬度与声发射信号的积分RMS有最好的相关关系。有可能利用积分RMS这一参数来估价岩石压入硬度,并进一步预报岩石可钻性。

| Abstract: | In order to explore the correlation of rock indentation hardness with acoustic emission parameters such as accumulated number of events, total energy, peak RMS and integrated RMS. nine different types of rocks were tested. It is indicated that there is the best correlation between rock indentation hardness and integrated RMS of AE events. It is possible to use the parameter integrated RMS to assess rock indentation hardness and further to predict rock drillability. |

| Keywords: | rock indentation hardness acoustic emission AE RMS (root of mean square of acoustic emission) |
