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

development

The steel capsule was developed in May 1955 within 5 days of an accident at the Dahlbusch colliery in Gelsenkirchen-Rotthausen . Its small diameter of 38.5 centimeters allowed it to be used as a rescue device from drilling diameters of 40 centimeters. The invention was a joint mining development at the Dahlbusch colliery. A patent was never applied for.

The Dahlbusch bomb got its name from the press based on its bomb-shaped shape and its first use at the Dahlbusch colliery.

Calls

Since their invention, the Dahlbusch bomb and similar rescue capsules have been used in various mine accidents:

  • The Dahlbusch bomb was used for the first time at the Dahlbusch colliery. There, with their help, three miners, who were trapped by a collapsed blind shaft in a filling point between the tenth and eleventh levels , were cleared after five days - on May 12, 1955 - through a 42-meter-long vertical bore from the eleventh level upwards from 855 Meters depth saved.
  • In a mine accident in the Gustav mine on November 13, 1957, two miners were also rescued with the Dahlbusch bomb after 121 hours.
  • The Dahlbusch bomb gained further fame on November 7, 1963, when it was used to rescue eleven miners from the Mathilde iron ore mine after the Lengede disaster .
  • After the mining accident in Lassing in 1998, a miner was pulled out with a capsule from a depth of 60 m after ten days.
  • In 2002, nine miners were trapped underground at a depth of approximately 75 m after a massive water ingress in the Quecreek Mine , a coal mine in Lincoln Township , Somerset County , Pennsylvania, USA. After four days they were rescued by drilling a hole using an escape capsule, the design of which was derived from the Dahlbusch bomb.
  • The Phoenix 2 rescue capsule used in the San José mine disaster in 2010 was 53 centimeters in diameter and was significantly more spacious than the Dahlbusch bombs with 38.5 centimeters in diameter.
