This seed, from back in mid 2012, works in MC 1.5.2 and produces a hole that goes all the way to Y=12 directly.
The hole intersects caves and ravines at several levels.
Gold ore can be seen near the bottom.
The seed is "8700829340959843130". No quotes and no extra spaces.
There are no dangerous weapons. There are only dangerous people. R.A. Heinlein
If you aren't part of the solution, then you obviously weren't properly dissolved.
