摘要
在矿山井下巷道中采用静态胀裂剂破裂岩体、检测记录这一过程中的声发射（AE）信号。结果表明,岩体声发射活动峰值宏观裂纹出现,声发射信号频谱分布范围宽广,信号在岩体中传播时衰减十分迅速。
Acoustic Emission (AE) charaters were tested during rockmass was broken artificially by expanding material in an underground mine. It indicated that AE peak value appeared earlier than displacment, AE frequency spectrum was wide and AE parameters declined rapidly in rockmass.
