Research of monitoring technology in mine earch-sourd

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 earch-sound sensors attached to bolt. Analyzing the variety and characteristics of the AE signal, the system can predict coal and gas outburst or rockburst.
