The water was drained (20 m3 per hour) using a ten-horsepower steam engine consisting of a horizontal cylinder and gears.

In September 1856, a 12-horsepower direct-drive steam engine accompanied by pumps was ordered from Le Creusot for dewatering; this equipment was operational in June 1857 and sinking resumed.

[2] In May 1858, the installation of the dodecagonal casing, made up of sides 94 centimetres wide and a total height of 98.50 metres, was completed.

[3] However, the casing was fragile and eventually began to leak, so a small pump driven by a four-horsepower steam engine was installed 104 metres above the surface in June 1873.

[5] The 60 hp motor[6] driving the winding engine came from the cleat machine at Saint-Charles, and drove the coils via gears.

The Sainte-Barbe shaft was used as an air outlet, and its opening was closed by mobile flaps that were raised by the extraction cages when they reached the surface revenue.

At the beginning of the 21st century, the well was located in a clearing near the Champagney ballastières, on the edge of the Bois des Époisses.

A sign explaining the history of the Sainte-Pauline and Sainte-Barbe wells was installed at the start of the trail in the autumn of 2017.

After the well was abandoned, the slag heap was gradually overgrown by woodland, before a sand pit was built between the late 1960s and early 1990s, which radically altered and leveled the site.
