I worked as a Hard Rock Miner for over 2years in N.Ontario Canada back in 1977-80, a "Shockwave" is a deadly component of an explosion...buddy and I were in a drift preparing to load holes at the stope edge when a production crew set off an undercut blast without yelling "fire in the hole clear for blast", the 4 protocols of descent failed (4 safety stops before descending by a skip hoist cage into a mile deep hole in the Cambrian Shield) nobody knew buddy and I were at that level in an actively charged stope...the shock wave hit us with a white hot flash and then tossed us (luckily) 30ft over freshly blasted muck (hard rock), it was like we were picked up and floated over the muck and I'm looking down watching the jagged muck pass under me then we were dropped...ANYWAYS...I've been around a lot of these blasts and loaded a lot of Tovex, Nilite and AMEX.
MEANINGLESS FYI...A SHOCK WAVE IS A DISTURBANCE IN THE ATMOSPHERE CAUSED BY A SUPERSONIC PROJECTILE, THE PROJECTILE IN THIS CASE IS THE CAMBRIAN SHIELD.

cool, pressure waves like that build up in musical instruments. This is just on another scale, to the point you can actually see the pressure waves in the air.

I see what you did there.

Is a pressure wave bouncing off either end of the tunnel?

Yep. It's how wind instruments work except that's such a deep bass no human ear could perceive it.

HOLY BUCKETS

IT TRAVELS 7-8 TIMES FASTER THAN SOUND…

Apprx. 14,400 mph

That’s awesome.

We called detonation chord "B LINE"...it was yellow with a red lay the length of the chord...the stuff is amazingly powerful, if we had to shorten the length of a steel ductile water pipe we would wrap the circumference with a strand of chord and charge it...nice clean cut. I've worked with explosives most of my life (now part time)...physics is fun...the key to a good blast is pressure retention, the key to proper blast design is in the ignition delay of the caps. Implosions are delay sensitive.

It was a tunnel, now technically it's a flute.

Technically I guess it would be a Helmholtz resonator.

It looks like the beam in the death star.

Any back story on why they fired a small shot in a finished tunnel?

Bowing things up is good and Godly.

Moral of the story: be careful where you light your farts.
