Overview
- The explosion that hit a legal coal mine in Sutatausa on Monday left nine workers dead and six hurt, according to the National Mining Agency.
- Fifteen miners were underground at the time; three got out on their own and rescuers brought three more to the surface, with all six survivors treated at a local hospital.
- Officials said a buildup of gases caused the blast, and rescue teams first checked gas levels in the shafts before entering the site.
- The agency had inspected the operation on April 9 and urged steps such as sealing unused work areas and controlling coal dust because of methane risks, and authorities are now reviewing compliance.
- Local reports identify the operator as Carbonera Los Pinos in a zone where accidents are common due to poor ventilation, with crews working roughly 600 meters below ground.
