摘　　要：文章通过对室内和现场采集到的岩体声发射信号波形分析,寻找到岩体在外界因素影响下从稳定状态发展变化到破裂阶段的波形变化规律,可用以判断岩体的危险性。该规律为采场、隧道工程的安全施工提供了可靠的预报信息,有一定的实际意义。Through analyzing waveform of rock acoustic emission signal collected in acoustic emission laboratory and on site, the paper found waveform changing rule of rock from stability to fracture under effects of environmental factors, which could judge danger of rock. The rule provided reliable forecasting information for safe construction of stope and tunnel and has certain practical significance.
