Local authorities disclosed that the mine had operated under a governmental permit aimed at extracting minerals for graphite production. Previously, the site was a significant mining operation until its closure in 2018, serving intermittently for anthracite extraction by private firms thereafter. The exact number of miners present during the explosion remains unclear. In light of this tragedy, Asturias President Adrián Barbón has declared two days of mourning in honor of the deceased. The regional civil protection plan was activated at a minimal level, indicating that local resources were being utilized to manage the situation. Prime Minister Pedro Sánchez extended his sympathies through social media, sending condolences to victims' families and wishing for the quick recovery of the injured.
