" I'll just signal my location by creating an earthquake - they can trace me by the fallen debris " ;-) |

Normzone...I am thinking more along the lines of tapping on a rock, not earthqauke starting strength |
|
|
Sorry, bad signal-to-noise ratio likely. With the
reverberations a long-wall mine excavator
makes, I don't think the tapping is going to be heard. |

The various veins and impurities would have
different resonant frequencies and therefore make it
very difficult to communicate an intelligible signal
through them. |
