A giant open-pit coal mine in Spain's Galicia region, which had been used for years, has been transformed into a completely different place after operations ceased. Located in As Pontes in the A Coruña province, the mine cavity has been filled with approximately 547 billion liters of water, becoming one of the country's largest artificial lakes.
In 2008, Spain began filling a 300-metre-deep coal mine with 547 billion litres of water; four years later, it became one of the country’s largest artificial lakes
A vast Spanish coal mine pit was transformed into a large artificial lake. Engineers filled the enormous hole with approximately 547 billion litres of water. This process took over four years to complete, creating a new natural habitat. The lake now features a sandy beach and nature trails, earning eco-label certification. This successful rehabilitation offers a model for other former mining sites globally.
In 2008, Spain began to fill a decades-old coal mine, dug 300 metres deep near As Pontes, Galicia. The aim was to drown a huge hole left by years of lignite extraction to make it a lake. The pumping was completed on 18 April 2012, just over four years after its launch. In total, about 547 billion litres were poured into the pit, according to an engineering study of 2023 published in the journal Boletín Geológico y Minero and conducted by researc…
In Spain, a massive open-pit coal mine, closed after 60 years of devastation, has been transformed into one of the country's largest lakes through an engineering feat. The 865-hectare site, filled with 547 billion liters of water, has been awarded the Blue Flag and become a tourist destination.
Spain Turned a 300-Metre-Deep Coal Mine Into A Massive Artificial Lake. Here’s How
Imagine a hole nearly as deep as the Eiffel Tower is tall and spread across an area equal to around 1,600 American football fields. That was the scale of the As Pontes coal mine in Galicia, northwest Spain. For nearly 60 years, the mine was used to extract lignite, a type of brown coal. Over time, mining created a huge pit more than 300 metres deep. But the giant hole did not remain empty. After the mine was closed, engineers began an ambitious …
