An adit is a near-horizontal entrance or tunnel driven into a hillside or mountain for underground operations featuring only one opening to the surface. Adits offer a cost-effective safer alternative to vertical shafts. An adit allows workers to walk into a mine unlike vertical shafts to reach areas of interest directly. Because they are driven at a slight upward angle they allow water to drain out naturally removing the need for pumps. Adits also provide natural airflow for underground operations. Project 816 in Chongqing China is a massive decommissioned underground nuclear plant often cited as the world's largest artificial cave featuring over 20 kilometers of tunnels and 13 levels. Built in the 1960s to produce atomic bomb fuel it was designed to withstand nuclear hits with 18000 workers creating a facility that is now a tourist attraction. Key Details of Project 816:Structure: The complex contains 18 major caves over 130 tunnels and 80 roads.<br /> Design & Safety: It was built inside a mountain to resist a 1-megaton hydrogen bomb airburst and a magnitude-8 earthquake. Scale: The reactor hall is massive measuring 79.6 meters in height. Status: Construction was halted in 1984 85% complete due to shifting geopolitics.
