An experiment simulating coal seam under forced vibration conditions was conducted.
Acceleration response and microseism signal during the experiment were collected and analyzed.
It is found that, with an increasing amount of vibration, the natural frequency of the specimen decreases, and this phenomenon reflects fractures appearing in the specimen.
Acceleration response signals show that peaks in shock excitation frequency and shock excitation acceleration affect the acceleration response, which reflects damage to the specimen.
When shock excitation frequency nears natural frequency, the acceleration response first decreases and then increases.
When resonance occurs, it reaches its maximum value.
As shock excitation acceleration peaks increase, the acceleration response peak of the specimen also increases.
We conclude that destruction is mainly concentrated in the coal seam evidenced by specimen destruction situation.
Then shock excitation frequency and shock excitation acceleration influence on microseism signals were analyzed by Hilbert-Huang transform.
By receiving these signals and analyzing their characteristics, it is beneficial to develop new methods to predict disasters underground dynamically in the future.
