Friends:
can i get sound levels from open site blasting in mines, at different
distances, for example, in the web?
Thanks

Yes. The Bureau of Mines and Office of Surface Mining have a lot of
reports available for free download. I don't have a URL handy, but I
recall it was not hard to locate with a google search.

Blast noise from mines is fairly situation dependent, so don't look
for simple relations based on only the charge. There can also be
significant seismic propagation.

Weather conditions are also important. A temperature inversion will bend
sound back to ground level while the same sound will get bent into the sky
if the temperature of the air decreases rapidly with amplitude. This effect
is very obvious where I live, about a mile or two from a jet airport.
