The grooves, which are connected to those in the Jekerdal at Beurs, Glaaien and Sluizen, have probably already been used in the pre-Roman times. In addition to marl, silex was also won.
Originally they worked in pits, and only later in the process were horizontal corridors carved out: The marl is close to the surface here.
There are three corridors, also called caves. The entrance to the largest is in a grove, which gives access to the Great Cave. From the Roman era, marlstone blocks were carved out which served as substructure for buildings. Marel from this quarry was also used for the construction of the Basilica of Tongeren. The marl was also used as a fertilizer on the fields. Until 1835 marl was extracted here.
The erratic relief created by human activity with scrub. In the Middle Ages, these slopes were used for viticulture. The underground corridors, sometimes with ventilation ducts in the field, continue into the neighboring municipalities.
From about 1930 onwards, the corridors were used for mushroom cultivation. The collapse at Zichen in 1958, in which 18 people fell, also meant the end of mushroom cultivation in the caves of Henisdaal.
