矿井地音监测技术的研究

Research of monitoring technology in mine earch-sourd

本文针对煤岩体声发射信号的特点以及地音监测实时性的要求,提出了一种基于DSP的地音监测系统的设计方案,通过安装在锚杆上的地音传感器,连续监测工作面前方的煤岩体声发射活动的变化规律和特征,实现对矿井动力灾害的预测预报。

Combining with the characteristics of the coal and rock AE signal and the real-time processing request of coal and rock AE monitoring, the thesis presents and realizes a AE monitoring system which is based on DSP. The system continuously monitors the AE signal ahead of the working face by the earchsound sensors attached to bolt. Analyzing the variety and characteristics of the AE signal, the system can predict coal and gas outburst or rockburst.
