Before this thread now promptly dies, I want to recall for you a little 
power boat model I was given as a child. This has only a tenuous relation 
to a blowing mine shaft.   Now if it had been a panting mine shaft!

 The propulsion was straight forward. A loop of small bore copper tube
was heated by an alcohol burner, and the two ends of the tubing were led
 out of the transom.  With no other mechanical parts, it would put-put-put 
through the water quite convincingly.
 It seems the two water columns exited more promptly to the rear than they 
reentered.
