Dahlbusch Bomb

The Dahlbusch bomb (also Dahlbusch bomb or Dahlbusch rescue bomb ) is a 2.5 meter long and 38.5 inches wide, torpedo-shaped rescue capsule that can be used in mining to the rescue of buried miners.

Development

The steel capsule was developed in May out in 1955 on direct cause of an accident at the coal mine Dahlbusch in Gelsenkirchen- Rotthausen within 5 days. Their low diameter of 38.5 centimeters allowed their use as rescue equipment from bore diameters of 40 inches in diameter. The invention was a mining community development at the mine Dahlbusch. It was never applied for a patent.

It was named Dahlbusch bomb by the press in accordance with their bomb- shaped form and at its first use on the mine Dahlbusch.

Inserts

Since its invention, the Dahlbusch bomb and similar rescue capsules at various mine disasters were used:

• Was first used in the Dahlbusch bomb at Zeche Dahlbusch. There were with their help three miners who were trapped in a filling location between the tenth and eleventh sole by means of a collapsed blind shaft, after five days - on 12 May 1955 - by a 42 meter long vertical bore of the eleventh sole upward from 855 rescued meters depth.
• More awareness gained Dahlbusch bomb on 7 November 1963, when she succeeded to the rescue of eleven miners after mine disaster in Dark Places of the iron ore mine Mathilde.
• After the mine disaster of Lassing a miner was pulled out in 1998 after ten days with a capsule from 60 m depth.
• In 2002, nine miners were after a massive flooding in the Quecreek Mine, a coal mine in Lincoln Township, Somerset County, Pennsylvania, USA, included in about 75 m depth below ground. After four days, they were rescued through a hole from the rescue capsule, whose design was derived from the Dahlbusch bomb.
• The rescue capsule used in the 2010 mining accident in San José was significantly roomier than the Dahlbusch bombs with 38.5 cm diameter by 53 cm in diameter. But this goes back to their design.
