Between 1917 and 1922, in order to ensure and adequately develop its coal supply, the Sociedad Metalúrgica Duro-Felguera endeavoured to deepen this historic shaft, which was to be a pioneer due to its vertical mining system, and which is now one of the emblematic shafts - now in the hands of Hunosa - which continues to write historic pages of the many vicissitudes of Asturian mining.
In Sotón, in those first decades of the 20th century, Duro-Felguera tried out everything it had learnt in previous deepening operations, building a shaft with a spongy internal structure that was more efficient technologically and architecturally.
On the outside, the shaft sits on a wide esplanade reclaimed from the river Nalón, which has allowed it to develop a series of auxiliary installations in complete freedom, one of the most striking elements being its spectacular derrick.
