Shaft Sinking Methods: Caisson Method and Cementation ...
The progress available with shaft sinking machines may be appreciated from the following performance of a machine manufactured by WIRTH, a leading manufacturer in West Germany. In early 1983, one 7 m diam. shaft was sunk in Alabama, U.S.A., completing the sinking of the shaft, 650 m depth, in 6 weeks. Sinking rate at one stage was 35 m/day.
In practice, at the bottom of shaft is usually full of water during sinking. therefore, high density, water-resistant explosives are used. Lashing and mucking. Lashing is made for the loading of muck into a conveyance for its disposal. This activity is a time consuming activity due to Presence of water, limited space. Support or shaft lining
