摘要
Abstract
The drill bit breaking rock would produce broadband vibration signal, different frequency represents different in-formation.Due to the lower energy and higher attenuation, the high frequency signal is difficult to be detected.In this pa-per, 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 characteris-tics in low frequency.关键词
