You must establish either a vertical shaft or a horizontal shaft into the side of a hill. Dig it so that you have approximately twice as much earth above the tunnel as the height of the tunnel itself. Example: a 3-foot high tunnel will need 6 feet of earth above it. This will help avoid collapse.

Geologists use the term “massive” to describe rock that is uniform without layers or joints. Unfortunately, not all rock is massive.
