Special Methods For Shaft Sinking. In the process of shaft sinking, it becomes necessary to adopt a special method if the ground through which the shaft is sunk is loose or unstable such as in sand, mud, gravel, or alluvium, or when an excessive amount of water is encountered, which cannot be dealt with by sinking some situations, both sets of these conditions may be encountered.   (shaft) sinking by freezing, shafting by freezing, (shaft) deepening by freezing, shaft working by freezing, (shaft) putting down by freezing Gefrier(schacht)abteufen n, Gefrier(schacht)abteufung f.   The special construction technology mainly would include ground freezing methods, full diameter shaft drilling methods, caisson methods, grouting technology and concrete curtain methods as well as other methods. The paper summarizes the shaft sinking numbers and effects by the special construction methods during different periods. rate of shaft-sinking advance in hard rock since Except at great depth, shafts sunk in hard rock mines do not normally require special considerations to maintain wall stability. A few shafts require the ground freezing method to traverse a waterbearing horizon.

Conventional mine shaft sinking methods involve the performance of a cycle of different operations—drilling and blasting, removal of smoke and cleaning of fly-rock lodged on overhead timbers, mucking and hoisting of the broken rock, and timbering. The latter (a) may be the last operation of the cycle, (b) may be carried on during drilling and mucking, provided it is done from a substantial. Shaft sinking Fig 3 The inclined shaft Freezing The freezing method in vertical shaft drilling has become a mature technique. When it is applied to inclined shaft construction, the inclined shaft freezing drilling method can be adopted as shown in Fig. 3. Tunnels and subways. The Thyssen Group has used this ground stabilization method for over years with the first artificial ground freeze project having been completed in In , Thyssen Mining introduced artificial ground freezing to the Canadian mining industry when the first potash shaft in Saskatchewan was successfully sunk to depth.   Groundwater Control Techniques for Tunnelling and Shaft Sinking Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

""Abstract: Khalashpir coal field is the 3rd largest coal field in Bangladesh, where coal occurs at depths of m to m below the surface. Considering the Geological, Geo-environment and other related geoengineering information. Thyssen Mining | Shaft Sinking. Thyssen Mining has been sinking shafts worldwide for over years. Whether it’s using conventional drill and blast methods or innovative mechanized systems, Thyssen Mining’s techniques continue to excel and grow as technology advances and safety standards increase. As removing heat from the ground is the main feature of the method, an efficient thermal design of the freezing process is mandatory to ensure success of the shaft sinking operation.   Shaft sinking 1.
