摘　　要：目前电磁辐射法是预测煤与瓦斯突出、冲击地压等煤岩动力灾害的先进技术,能够实现非接触、无损、实时监测,但其准确性和高效性有待提高。通过对国内外专家学者研究的整理,以综述的形式,从电磁辐射研究对象、产生机理、频谱特性等几个方面对煤岩破碎电磁辐射预测技术的研究进展进行分析总结。分析讨论后发现电磁辐射法在产生机理、低频信号、频谱特性及影响因素定量化分析、实验室尺度与工程尺度下电磁辐射变化规律的相关性等方面依旧存在不足,并针对其不足提出电磁辐射技术未来的研究方向。Electromagnetic emission method is an advanced technology to predict coal and gas outburst,rock burst and other dynamic disasters of coal and rock.It can realize non-contact,non-destructive and real-time monitoring,but its accuracy and efficiency need to be improved.Through sorting out the research of domestic and foreign experts and scholars,this paper analyzes and summarizes the research progress of coal and rock crushing electromagnetic radiation prediction technology from the research object of electromagnetic radiation,generation mechanism,spectrum characteristics and other aspects in the form of review.After analysis and discussion,it is found that the electromagnetic radiation method still has shortcomings in the generation mechanism,low-frequency signal,spectrum characteristics and quantitative analysis of influencing factors,and the correlation between the changes of electromagnetic radiation in the laboratory scale and the engineering scale.The future research direction of electromagnetic emission technology is proposed.
