In the heart of Asturias, Spain, lies a fascinating relic of industrial history: Pozo Barredo. This once-thriving coal mine in Mieres offers a glimpse into the region's rich mining heritage, making it a noteworthy destination for history enthusiasts and curious travelers alike. The story of Pozo Barredo is one of perseverance, innovation, and transformation, reflecting the broader narrative of Spain's industrial evolution.
Pozo Barredo's origins date back to the early 20th century when it was developed by the Fábrica de Mieres, a prominent company in the region. The mine was established to exploit the rich coal seams beneath the valley, continuing the work of earlier mines such as Mariana and Corujas. These initial efforts laid the groundwork for what would become one of the most significant mining operations in Asturias.
The mine's construction began in earnest in 1936, during a period of intense industrial activity. Despite the challenges posed by the Spanish Civil War and the subsequent economic difficulties, the project progressed, and by 1941, Pozo Barredo was fully operational. The mine featured a vertical shaft with a headframe, or castillete, which quickly became an iconic symbol of Mieres' industrial landscape.
The engineering feats achieved at Pozo Barredo are truly remarkable. The mine's vertical shaft reached a depth of 355 meters, connecting five levels of underground workings. This intricate network was accessed by two cages, each capable of transporting four wagons of coal at a time. These cages were operated by a double-drum winding engine, powered by an electric motor, showcasing the technological advancements of the era.
One of the most significant engineering projects associated with Pozo Barredo was the construction of a balance shaft, or pozo balanza, which replaced the traditional inclined planes used to transport coal from the upper levels of the Mariana mine. This innovation allowed for more efficient extraction and transport of coal, significantly boosting production levels.

Throughout its operational years, Pozo Barredo was a bustling hub of activity. The mine not only provided employment for hundreds of workers but also played a crucial role in the local economy. The extracted coal was transported via a network of railways and aerial cableways, connecting the mine to processing facilities and markets beyond Mieres.
In addition to coal extraction, the site housed various ancillary facilities, including a washery and an electric power plant. These installations were essential for processing the raw coal and providing the necessary energy to power the mine's operations. The washery, in particular, was a vital component, as it ensured that the coal met the quality standards required for industrial use.
Like many industrial sites, Pozo Barredo experienced its share of struggles and labor disputes. One of the most notable events in the mine's history occurred during the Christmas season of 1991, when 36 union leaders from the SOMA-UGT and the Sindicato Regional de la Minería de CC.OO. de Asturias staged a protest inside the mine. This dramatic action was in response to the proposed Industrial Restructuring Plan for HUNOSA, the state-owned mining company that had taken over Pozo Barredo in 1967.
The protest garnered significant attention and support, highlighting the deep connection between the mine and the local community. The demonstrators were visited by prominent union leaders, and their efforts culminated in a massive rally on January 3, 1992, underscoring the solidarity and resolve of the mining workforce.
By the early 1990s, the decline of the coal industry led to the cessation of extraction activities at Pozo Barredo. The mine officially closed in 1994, marking the end of an era. However, the site's legacy continued through various initiatives aimed at preserving its historical and cultural significance.
One of the most innovative transformations involved the use of the mine's water pumping system for geothermal energy. Today, the water extracted from Pozo Barredo is utilized for heating and cooling several buildings in Mieres, demonstrating a forward-thinking approach to sustainable energy use and the adaptive reuse of industrial heritage sites.
For visitors, Pozo Barredo offers a unique opportunity to explore a pivotal chapter in Asturias' industrial history. The site stands as a testament to the ingenuity and resilience of the mining community, with its towering headframe serving as a poignant reminder of the region's coal mining legacy.
Whether you're a history buff, an engineering enthusiast, or simply curious about the past, a visit to Pozo Barredo provides a fascinating journey through time. As you walk the grounds and learn about the site's storied past, you'll gain a deeper appreciation for the hard work and determination that fueled Asturias' industrial growth.
In conclusion, Pozo Barredo is more than just a former coal mine; it is a symbol of the enduring spirit of Mieres and its people. Its history, marked by innovation, struggle, and transformation, continues to inspire and educate, making it an essential stop for anyone exploring the rich industrial heritage of northern Spain.
