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. Source

The construction of vertical shafts for accessing the potash deposits is a highly challenging engineering task and an essential element in the success of the overall mining project. The operation essentially involves the safe and efficient sinking and construction of the shafts and the installation of an effective water seal to protect the salt and potash strata from hydrolysis and flooding - an event that would result in the total or partial loss of the deposit. This report describes the technical procedures employed during the sinking and construction of two vertical mine shafts designed to provide access to the potash deposits of OAO 'MHK EuroChem' in the Perm region of Russia and to develop the Palasherski potash deposit being mined by EuroChem in the Russian Federation. As well as outlining the planning and project development requirements the paper presents the technical aspects of the freeze-hole drilling and ground freezing operations and the installation of the tubbing lining and goes on to describe some features of the mechanised shaft sinking system. It also presents the technology employed for installing the wedge ring ("Keilkranz)", that is used as sealing elements for the shaft lining. Source

The 'three-bunker project' described in this paper comprised the excavation and fitting-out of three gravity-fed coal bunkers at Prosper-Haniel and Auguste-Victoria collieries. The three installations were to be constructed one immediately after the other in order to save time and money. One major advantage of this approach was that the engineering could be carried out as part of a concentrated effort. The engineering services undertaken at one project site could then be adopted - either completely or with some slight modification - at the next bunker. Another huge benefit was in the provision of logistics: after working on one bunker the mechanised equipment could immediately be deployed to the next site. RAG Deutsche Steinkohle AG (now RAG Aktiengesellschaft) put the three-bunker project out to tender in the summer of 2009 (see Table 1). The mining division of Thyssen Schachtbau GmbH (TS) submitted a bid for the contract and was given the go-ahead in the winter of 2009/2010. The projects were to be completed between late 2009 and the end of 2012. ©2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

The sinking and lining of shafts at mines to access mineral deposits and shafts for civil engineering works has always been a great challenge for clients, designers and contractors. The article deals with the drilling and pipe casing of freezing holes up to 820 m deep to construct shafts in potash and salt mines with a permissible vertical deviation of less than 0.6 m radius, the managing of the associated ground freezing with freezing plant up to 10 MW freezing capacity and conventional full shaft sinking of so-called ultra-deep mine shafts with final depths of more than 2,000 m using drill and blast. Drilling and specialised aspects of shaft construction are described, for example directional drilling for ground freezing, temperature monitoring for safe control of shaft sinking work in frozen ground, the working platform system as the central shaft equipment of the shaft builder for the efficient performance of sinking stages like the drilling of blast holes, loading muck, support against rock mass impacts and shaft lining. In addition to the technical challenges, the article also discusses specific construction management and logistical tasks, which can occur in mine projects in distant regions with weak infrastructure. An important part of the work of Thyssen Schachtbau GmbH is the sinking of shafts for potash mines. More than 60 mine shafts have been sunk for potash mines. Thyssen Schachtbau GmbH is currently involved in ten potash mine shaft projects in Russia. In addition to shafts for potash mining, shafts for access to non-ferrous metal deposits are also significant: two shafts more than 2,000 m deep are currently being sunk for a nickel mine north of the Arctic Circle. © 2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.
