| 摘 要： | 煤岩体的破坏伴随着声发射现象,通过分析煤岩体损伤破坏与声发射之间的耦合关系,论述了利用声发射评价冲击矿压危险的可行性,提出了冲击矿压危险性评价的声发射指标的表达方式、临界指标的确定以及危险等级的划分。实验室测试了某冲击矿压矿井煤样破坏过程的声发射特征,为现场应用提供参照。最后分析了波兰ARES声发射系统在冲击矿压矿井中的应用效果与存在的问题。

| 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, the effects and limitations of Polish ARES acoustic emission system at rockburst mine hazard are analyzed. |
