Die (mining)
In mining, the term `` Gesenk '' refers to a sunken blind shaft made from top to bottom . A die can be created either in the collapse of the passage or in a seiger manner. In the past, dies only had a rectangular cross-section, whereas today, as a rule, round or elliptical dies are created. The opposite of a die is a departure .
A die normally has no direct connection to the surface of the day or to a deeper floor. If the die penetrates with a deeper bottom , it is usually referred to as a blind shaft.
In the uranium ore mining of SDAG Wismut , short blind shafts, which connected a deeper secondary floor to a main floor without a filling point connection to a conveyor shaft, were referred to as dies.
use
The dies are used for conveying, transporting material and driving to and from deeper levels that cannot be reached directly from the main shaft ( substation construction ) or to investigate deeper parts of the deposit .
Dies can range from simple pit construction from old mining with a hand reel or even without conveyance to fully constructed blind shafts with one or two conveying systems.
Exceptions
Smaller day shafts are sometimes referred to as dies. In the course of the rehabilitation of uranium ore mining by Wismut GmbH , some new shafts, including several day shafts, were sunk and referred to as exploration sinks.
