Is anyone experienced in roman tunnels/chambers? Last month I went to check up on a location where we used to clear out a cave a couple of years ago and i heard about 8 loud bangs coming from deep underground about 5 minuetes apart.(i was standing outside) Yesterday I went there again and I heard it again,only this time it was 3 successive bangs like a large piece of rock falling & rolling. I've heard rumors that at some places people have heard the booby traps working underground and figured this is the only possible explanation. Strange thing is that we did'nt hear anything when we used to work on the cave, and we were there for 3 weeks.
