...压入硬度 压入试验 岩石可钻性 [gap=617]Key words MTS rock mechanics test system, indenter with falt fundus, indentation hardness, rock indentation, rock's drillability ..
It is indicated that there is the best correlation between rock indentationhardness and integrated RMS of AE events.
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。
2
It is possible to use the parameter integrated RMS to assess rock indentationhardness and further to predict rock drillability.
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。
