- Note
- "A Dahlbusch Bomb is an emergency evacuation device for use in mining. In its original form it is a torpedo-shaped cylinder with a length of 2.5 metres (8.2 ft), developed to transport trapped miners through boreholes after mining accidents. It does not contain explosive: it was called a "bomb" because of its shape.
The Dahlbusch Bomb was developed in May 1955 at the Zeche Dahlbusch coal mine in Gelsenkirchen in Germany´s Ruhr area to rescue three miners. Thirty-four-year-old engineer Eberhard Au sketched it on a leaflet. Au, who never applied for a patent, was quoted as saying "the main thing is, the lads get out". Its distinguishing feature was the small diameter of only 38.5 centimetres (15.2 in), which allows miners to be evacuated through significantly smaller boreholes than using other evacuation devices, and whose shape also helps in raising and lowering the device across long distances. At Zeche Dahlbusch, the device was successfully used to rescue three miners, trapped at a depth of 855 metres (2,805 ft) after a mine collapse, through a vertical borehole drilled 42 metres (138 ft) from the next-higher mine level." - (en.wikipedia.org 14.07.2021)
