Small shrine dedicated to "Tio" (Miners never call him the devil). Since god lives in heaven, they believe that Tio lives underground. Offerings are made to him regularly (Alcohol, soft drinks, cigarettes, coca leaves, etc.). The offerings are made so that miners can take the minerals from him and to keep them safe.

A small museum in the mine

Inside the mine

A miner shows how dynamite is used, a stick is broken up and put together in a bad with the Ammonium Nitrate, a fuse is then added

Complete dynamite package, here a person is holding the bag. Notice that it's lit (It had about 2 minutes left on the fuse though)
