摘要
根据煤岩破裂产生的冲击破坏机理,提出了煤岩冲击破坏的弹塑脆性模型,并利用该模型分析如何进行冲击矿压危险性预测;介绍了声发射以及电磁辐射技术的机理和监测原理。
Based on coal and rock burst failure mechanism,the elastic-plasticbrittle model of coal and rock burst failure was presented and taken advantage of to analyse how to carry out the danger of rock burst prediction,acoustic emission and electromagnetic radiation mechanism and monitoring technologies was introduced.
