摘要
声发射技术是一项很有发展前景的应用技术.本文报道了岩石力学领域内应用声发射的一般概貌,介绍了其在构造应力场、岩石脆性破坏的理论机制、坚硬岩石中地下采矿及采煤过程中经常发生的冒顶、岩爆的监测预报等研究概况,并简述了声发射技术在地震预报、古构造应力场研究及天然滑坡和露天矿边坡失稳等方面的应用.
The acoustic emission skill of rock is an applied technique with a bright future. This paper presents a general sketch of the use of acoustic emission in the area of rock mechanics. Then it describes the applications of acoustic emission techniques in measurement of tectonic stresses. Special emphasis is given on the research of theoretical mechanism of brittle rock failure. The paper also introduces the applications of acoustic emission techniques to the monitoring and prediction of roof fall, rock bursts in underground hard rock mines and coal mines, the prediction of earthquakes, the sliding of rock slopes in nature or open pits.
