摘　　要：通过分析声发射技术的原理及特点,探讨其在煤矿瓦斯异常监测、岩层稳定性监测及机械设备监测中的应用流程。以某煤矿采煤工作面为例,开展为期30 d的声发射监测实验。实验结果表明,随着时间推移,岩层声发射活动呈现明显增强趋势,稳定性逐步降低,存在失稳风险。By analyzing the principles and characteristics of acoustic emission technology,this paper explores its application process in monitoring gas anomalies,rock stability,and mechanical equipment in coal mines.Taking a coal mining face as an example,a 30 day acoustic emission monitoring experiment was conducted.The experimental results indicate that with the passage of time,the acoustic emission activity of rock layers shows a significant increasing trend,and the stability gradually decreases,indicating the risk of instability.
