摘　　要：岩体声发射监测是矿山岩体灾害监测预警的重要手段,目前国内在矿山岩体声发射监测方面都开发出了相应的监控系统产品,但大都采用有线的方式。为使研究设计中减少系统现场安装和维护的工作量,避免监控盲区,设计了一种无线的岩体声发射监测系统,即系统由多个平行的检测通道构成,能实时采集和显示声发射波形信号,准确分析、研究监测部位岩体形状,提高预警的准确性,有广阔的应用前景。It is an important method to monitor the AE （ acoustic emission） for the rock mass disaster prediction. At present, there are several research departments that have done some good work on these. Some AE monitoring system have been designed and applied. But most of them communicate by electric cable. In order to decrease the work of installation and maintenance and avoid the dead zone of monitoring, designs one wireless signal monitoring system for rock acoustic emission. This system is made up of multi-parallel test channels, which can real-time collect and display the wave signal from AE, correctly analyzes and research the monitored rock shape, improve the efficiency of forecasting and has a wide application prospect.
