Fire pots
As fire buckets , even boilers or fire hook is called in mining an old method that was used to create an artificial Wetterzug in the mine workings. Boiling is the oldest method of creating an artificial weather train .
execution
A vessel made of iron rods assembled in a grid-like manner was required to carry this out. This vessel, known as a fire basin or fire bucket , had a bracket at the upper open end to which a chain or wire rope was attached to fasten the fire bucket. Subsequently, the vessel was filled with burning coals above ground and hung in the weather shaft by means of a reel and lowered to the lowest level. Instead of the coals, charcoal or coke was also used. The miners kept the fire burning underground . The heat of the fire warmed the weather in the shaft and rose to the top, creating a current of air. As a result, the weather was sucked out of the mine workings and also weathered, the fresh weather flowed in through the other openings, and artificial ventilation was created . However, the method could not be carried out in shafts in which there was a shaft separator to separate the weather .
hazards
Because of the open fire, this method was dangerous in shafts with wooden joists . It was also dangerous to use in mines with bad weather and was often prohibited. Attempts were made to reduce these dangers by covering the fire cauldrons with a metal gauze, which was also common on miner's lamps . Due to the dangers involved, this type of ventilation has been banned over time.
