Company history

Deilmann-Haniel GmbH has always been a pioneer when it comes to new technologies or methodologies. We have played a leading role in the development and introduction of many new technologies.

1884 Development of the German tubbing by Haniel & Lueg Ltd
1913 / 1925 Sinking of the freeze shafts Bohrt 1 & 2 (502m freeze depth) and Wallach 1 & 2 (549m freeze depth) by Gebhardt and König Ltd
1955 / 1960 Freeze shafts Rossanray 1 & 2 with a welded rolled steel tubbing liner and concrete backfill
1956 / 1960 Auguste Victoria 7 freeze shaft with a floated double-walled steel lining and asphalt backfill
1957 / 1961 Freeze shaft Wulfen 1 & 2 using a composite shaft lining with a concrete filling between the inner and outer steel welded cylinders and asphalt backfill
1963 Auguste Viktoria 8: first steel / concrete composite lining with asphalt backfill, temporary support and flexible outer lining made from concrete blocks
1964 Замораживание грунтов до глубины 625 м на стволах Freeze depth of 625m in the Allan Shafts 1 & 2 in Saskatchewan
1976 / 1977 Siegmundshall Shaft: first steel liner tightly welded steel plating with mortar backfill
1981 Sinking and lining of the Y Shaft in Gardanne with 10m inner diameter and 1150m depth
1979 / 1985 Voerde shaft: steel-concrete-steel inner composite lining with an asphalt joint and a supporting flexible outer lining made from concrete blocks (600 m freeze depth)
1979 Worked on the theoretical solution for freeze sinking through the cracked zone in the transition area between the salt strata and bedrock. The practical solution was implemented at the Riedel 2 Ventilation Shaft as treatment of the cracked zone
2001 DIN 21500 shaft lining - concept and design
2009 Development of a shaft lining concept for water pressures up to approximately 10.5 MPa consisting of an outer welded steel liner and inner bolted steel plate liner with concrete fill for Canadian potash mining
