Working in mines is really dangerous. Even though the miners have the needed equipment, they work underground where the visibility can be limited but also the supply of oxygen is another risky thing. Accidents happen all the time, but many families find mine digging as a way to get a better existence.

Things to be more intriguing, the miners who lost their lives, dug 10 precious diamonds before the accident happened. Now no one knows where are those diamonds.
