Application Research of Acoustic Emission Technology in Coal Mine Safety Management
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.
