Former hard coal mine shaft in Heusweiler-Dilsburg, operated 1845–1931 then reactivated, whose 1977/78 concrete Förderturm — the only surviving tower-type headframe in the Saarland — is a listed monument in a commercial park.
Schacht Dilsburg is the sole surviving above-ground monument of the Grube Dilsburg, a small hard coal mine worked in the Köllertal at Heusweiler from 1845 until its definitive closure in 1931. Coal was extracted from Stollen from 1845 and from 1917 by Tiefbau under Heusweiler. In total, from 1845 to 1931, approximately 3.74 million tonnes of Steinkohle were extracted from the Grube Dilsburg.
Following closure in 1931, the Grubenfelder were worked from neighbouring mines, principally Ensdorf and Göttelborn. The Schacht Dilsburg was reactivated from 1965 by the Grube Ensdorf as a Wetterschacht, when the Ensdorf Westfeld workings reached beneath Heusweiler. Later, Grube Ensdorf constructed its own Anlage nearby at Niedersalbach — the Südschacht.
The Göttelborn mine also used the Schacht Dilsburg site when its workings extended north-west as far as Heusweiler. The 1977/78 concrete Förderturm, erected to replace the previous headframe structures when the shaft was serving as a Wetterschacht, is the only surviving Förderturm of tower construction in the Saarland. It was placed under Denkmalschutz in 2002.
The remaining Stollenmundlöcher on the site also survive.
The Grube Dilsburg lies in the Köllertal in the Gemeinde Heusweiler, south of Saarbrücken. The mine is documented from 1845 when Stollenbetrieb began; Tiefbau under Heusweiler commenced in 1917. Between 1845 and the closure of the mine in 1931 a total of approximately 3.74 million tonnes of hard coal (Steinkohle) were extracted.
Following the Stilllegung of the Grube Dilsburg in 1931, the underground Grubenfelder were subsequently worked from neighbouring collieries. The Grubenfeld Dilsburg was taken over in part by the Bergwerke Ensdorf and Göttelborn and mined from those surface complexes. From 1965 the Schacht Dilsburg was reaktiviert by the Grube Ensdorf to serve as a Wetterschacht, as the Ensdorf Westfeld workings advanced westward and reached beneath Heusweiler. In 1994 the shaft was used again for Seilfahrt to allow the extraction of coal from the Göttelborn connection. With the closure of the Grube Göttelborn on 1 September 2000, the Schacht Dilsburg was definitively closed and placed out of service.
The present headframe over Schacht Dilsburg was erected in 1977/78. It is a Förderturm in Betonbauweise — a concrete tower-type headframe — and is the only surviving Förderturm of this construction type in the entire Saarland coal district. The Saarland Landesdenkmalamt survey describes the Dilsburg headframe as serving as an Identifikationspunkt in the Gewerbegebiet that developed around the former mine site. The headframe was listed under Denkmalschutz in 2002. The surviving Stollenmundlöcher on the former Grube Dilsburg site document the earlier Stollenbetrieb tradition at the location and are visible in the Gewerbegebiet.
