After the Second World War, the Belgian authorities and those responsible for the coal industry strove to restore annual coal production to its 1938 level. Factories were outdated and severely affected by the lack of maintenance during the conflict. At the same time, competition from foreign coal became palpable. To survive, the Belgian coal industry had to undergo major restructuring. Few coal companies were aware of this necessity. One of these companies decided to concentrate its production at two of its sites, including this small, rather dilapidated colliery, which had the advantage of being situated in a key location within the concession. It was decided to build an extraction tower, as space was too limited for a conventional shaft frame with a ground-based machine. The company was able to rely on Marshall Plan funds to carry out modernizations, ranging from the complete renovation of its headquarters to the construction of a new sorting and washing facility.

The new pit was commissioned in 1954. Its daily production capacity was 3,000 tons per day. The shaft had a diameter of 5 meters and was equipped with an extraction machine jointly built by the Alsthom factory in Belfort, France, and the Ateliers du Thiriau in La Louvière. This machine had a power output of 3,300 horsepower and moved both four-story cages, each capable of transporting a 2.5-cubic-meter sedan, at a speed of 23 meters per second. The new installations remained in operation for only fifteen years and were closed in 1969.
