中文摘要:钻头破碎岩石时会产生宽频的振动信号，不同频段的信号蕴含了不同的信息，由于高频段信号能量低、衰减大，不易检测，因此，就钻头破岩信号在低频段特征进行了研究，通过不同岩性岩样的微钻实验数据分析，发现破碎不同岩性的岩石产生的信号在低频段具有固定的频率特征。

Indoor Experimental Study on Low Frequency Vibration Characteristics of Bit Breaking Rock
Abstract:The drill bit breaking rock would produce broadband vibration signal, different frequency represents different information. Due to the lower energy and higher attenuation, the high frequency signal is difficult to be detected. In this paper, the low frequency signal characteristics in the bit breaking rock are studied. By the analysis on micro-drill experiment data of different rocks, it is shown that the signals produced by bit breaking different rocks have fixed frequency characteristics in low frequency.
