地音监测在冲击危险性掘进工作面的应用

Application of Acoustic Emission Monitoring at Shock Risk Tunneling Face

以耿村煤矿13230掘进工作面地音监测系统为例,通过对一段时间内地音监测数据的统计分析,确定了13230掘进工作面塑性圈动态演化区的分布范围,得到了矿压显现与地音各参量之间的关系。

Taking acoustic emission monitoring system in Gengcun coal mine 13230 tunneling faces as an example,through statistical analysis of monitoring data for a period of time,got the relationship between mine pressure manifestation and various parameters,as while identified distribution area of plastic ring at 13230 tunneling face.
