As tonnlägig be mine workings , including shafts in mining , referred that do not cowardly , that extend perpendicularly but obliquely. The miner calls this lateral inclination of the shaft flattening. Further spellings for tonnlägig are donlägig , donnlägig or also dohnlägig .

Word origin

The term tonnlägig is derived from Tonnlege. Depending on the region, there were different spellings for barrel laying. Tonnlage , buoy position , buoy laying , Donläg , Donleger , Donlage , Donlege or Dohnlege . The term barrel laying is ambiguous. On the one hand, the term barrel laying describes a line that deviates from the Seiger line and goes down at an angle. If one imagines these lines in a right-angled triangle, then the hypotenuse is the pitch. On the other hand, the miner used to refer to an area in the shaft as a barrel, on which a bucket rests when it is pulled out of the pit. The term tonnlägig was initially only used for inclined shafts, in which the container (barrel) used for conveying was not suspended as in seigeren shafts, but rested on the wall of the shaft while it was moved in the shaft. Today in mining, the barrel laying is defined as an area on which a bucket still rests when it is pulled in the shaft on wheels. The miner speaks of tons when the incline to the horizontal is between 75 ° (83.33  g ) and 45 ° (50  g ). With larger angles of fall , the miner speaks of steep or seiger, while smaller angles of fall are referred to as flat.

application

Shafts with tonnages follow the collapse of the mineral dikes ( dike deposit ). This routing of the shafts was common in earlier centuries, as long crosscuts were avoided in this way . In addition, you could right the sinking of mine ore and thus generate revenue. The creation of a sloping shaft is also known as sinkhole sinking.
