Shaft sump

from Wikipedia, the free encyclopedia

In mining, the shaft sump is the part of the shaft that lies below the deepest floor . The shaft sump is the deepest point of the shaft.

construction

The so-called Kehrholzstation , also known as Kehrholz or Kehrholz , is located in the shaft sump . The reversal station is required to the twisting of the lower cables to prevent. The required depth of the shaft sump is determined by the height of the conveyor cage or conveyor frame. Some of the pit water accumulates in the shaft sump, which then has to be pumped for water retention . The miner describes the pumping of pit water from a full sump as sumps .

tasks

In addition, the shaft sump is used to take up the waste material from the shaft conveyance , the waste material must be removed regularly if necessary. For this purpose, a vessel ( bucket , trolley ) is attached under the cage by means of a rope construction and driven into the sump. There it is then manually filled by miners and emptied again on a midsole. In some shafts there is a so-called underpass bottom at the lowest point of the shaft sump. The shaft sump can be reached directly from this bottom. In most cases there is a scraper in it , with which the sump can be cleaned, which makes the laborious process of manual removal of the sediment superfluous.
