Medullary sheath (mining)
The term Markscheide comes from the medieval mining of Tyrol ( Schwaz ), Saxony ( Schneeberg ) and Bohemia ( Joachimsthal ). It refers to the boundary of a mining area , the area where a mine removal must operate. Mark is the old German word for border.
In the Middle Ages , the sometimes complicated ownership structure led to the construction of the step , and border symbols were carved into the rock in tunnels and stretches of neighboring pits. The medullary sheaths were marketed above ground with perforated stones .
Analogous to this, the office of the mark separator developed in the Middle Ages , a mining official who measured the markings and pits. The term Markscheidewesen called today for the surveying in mining.
