Weather sole
The weather bed is the floor through which the downpour in a mine is led to the extending weather shaft. As a rule, it is not intended for extraction, but exclusively for ventilation.
Counting method
During the transition from tunnel construction to civil engineering , the uppermost sole was used as a weather sole. In most mines, this sole was not taken into account in the numbering of the soles. Only the soles below the weather bed were numbered consecutively as civil engineering soles. This counting method was used until the end of the 19th century. From around 1895, a new mining authority regulation came into force, which said that when numbering the soles, the weather sole had to be included. From then on, the top sole, even if it was used as a weather sole, was the first sole.
Use of the weather sole
Which of the soles is used as a weather sole depends on whether the weather is sloping or rising. With sloping ventilation (downward ventilation ) the bottom floor is used as the weather floor, the fresh weather is led down from the top floor. In the case of ascending ventilation (upward ventilation), the uppermost level is the weather sole, the fresh weather is first directed to the lowest level and then upwards. In the case of downward ventilation, the weather flow and flow have the same direction; in the case of upward ventilation, they have opposite directions.
During the Second World War, mines where the weather bed could be reached via a tunnel were used by the population as an air raid shelter.
