冲击矿压的声发射监测技术研究
Study of acoustic emission monitoring technology for rockburst
摘要
Abstract
The feasibility of the monitoring technology of acoustic emission (AE) accompanying the fracture of coal and rock mass is discussed based on the analysis of coupling relationship between the damage failure and acoustic emission; and then the expression of rockburst risk assessment using acoustic emission index and its determination methods as well as classification of risk rank are put forward.The acoustic emission characteristics of coal samples under uniaxial compression are tested and obtained in the laboratory in order to provide reference for on-site application.Finally, che effects and limitations of Polish ARES acoustic emission system at rockburst mine hazard are analyzed.关键词
