Thyssen Schachtbau GmbH (TS) from Muelheim an der Ruhr (Germany) has been for five years intensively developing its business presence in the Russian Federation in the field of shaft sinking, drilling and freezing. At the moment various shaft sinking and freezing projects can be implemented for complete pleasure of our Customers. There are two especially remarkable projects in the Regions of Perm and Wolgograd, performed by TS under a contract with the Russian chemical and mining corporation “EuroChem”. In the Region of Perm two vertikal surface shafts of Usolski Potash Mine were sunk as frozen shafts. In addition to the shaft sinking technique TS was the first to use the innovative shaft thawing for fast temperature equalizing after shaft lining injection (“tamponage”) and time schedule progress. Three shafts were frozen down to a world record of 820 m deep in the Region of Volgograd, at the potash mine of Gremyachinsky GOK. In the course of past and current projects TS has been successfully and most reliably implementing the wishes of our Customers due to up-to-date techniques of shaft sinking, freezing and thawing. In future TS is planning to go on with technical development of equipment and calculation methods to be capable of realizing most challenging projects.
