I believe the tunnel is for an unfinished Let's Play, most likely for episode 200. That is why Geoff doesn't want anyone to see what's in it. There is a nether portal somewhere inside that tunnel which is what Jack came out of during Episode 100 and why Geoff instantly said for Jack to close his eyes etc.

or Jack could have exit to the portal in geoff's house
