摘　　要：针对矿山开采受煤岩动力灾害威胁的增加而引发对动力灾害监测技术及准确度提高的需要,综合利用电磁辐射测试和声发射监测机理,设计了电磁辐射与声发射矿井综合信息采集系统,实现了对电磁辐射和声发射信号的同步采集。该技术可有效提高采集系统的准确性和抗干扰能力,实现对煤岩动力灾害的准确监测和灾害评估分析。According to the increased coal and rock dynamic disaster threatening to the mining operation, induced the requirement to improve the monitoring and measurement technology and the accuracy of the dynamic disaster, with the application of the electromagnetic radiation measurement and test as well as the acoustic emission monitoring and measurement mechanism, the mine comprehensive information acquisition system of the electromagnetic radiation and the acoustic emission was designed and the signals of the electromagnetic radiation and the acoustic emission could be synchronously picked up. The technology could effectively improve the accuracy and anti - interference capacity of the information acquisition system and could have an accurate monitoring and measurement of the coal and rock dynamic disaster and the analysis on the disaster evaluation.
