Discovered in 1843, the first excavations were undertaken by the mining engineer
Alphonse Briart Alphonse Briart (1825–1898) was supervisor of the coal mines at Bascoup and Mariemont near Morlanwelz in the Hainaut province of Belgium, and a geologist who studied that region. During the period 1863–1896 he and Francois Cornet published a ...

Polishing strengthens the final product, making the axe- or adze-head last longer. The smooth surface also aids the cutting action by lowering friction with the wood. The axes were used initially for forest clearance during the

Conservation and access

An interpretative centre called ''SILEX'S'' opened in spring 2015. There is a museum on the surface and it is normally possible to descend into a mine.
