Author: Miguel Menegusto, December 2016

From pickaxes and manual classifiers to automatised extractors, with pressure washers and conveyor belts, the modern gold underground mining exploration has one more precious element to preserve:lives.
Miners are in constant risk with:
- Galleries kilometers deep underground
- Daily dynamite explosions
- Instable walls and tunnels
