摘要
在广泛参阅前人研究成果的基础上,阐述了煤岩破裂及其动力灾害的机理,介绍了声波、声发射、电磁辐射、地电和红外温度等技术在煤岩破裂探测方面的基本原理。总结了煤岩破裂探测技术在实验室及实际生产中的应用,分析了它们的优缺点以及需要改进或完善的方面。
After seeing previous articles in a wide range of basic research results, this text expatiates the mechanisms of coal rock fracture and its dynamic disasters, and introduces the basic principles of sound wave, acoustic emission, electromagnetic radiation, geoelectric and infrared temperature in detecting coal rock fracture, then summarizes the detection techniques of coal rock fracture＇s application in laboratory and actual production, and analyses their strengths and weaknesses as well as the need to improve or perfect.
