The definitive manual for exploring/inventorying abandoned mines comes from the Congressionally decommissioned US Bureau of Mines. In 1994, they released this document, which covers how to inventory and explore mines.

On page 62 of this manual the BLM admits to being in the process of writing guidelines for employees for mine entry. We call upon the BLM to publically release this document as soon as possible.
At the time this handbook was written, the Solid Minerals Division was developing underground site entry guidance. Field personnel should follow the most recent available guidance for underground site entry.
