Abstract (en)
A break point (3) is located above a safety valve (2) in a pipe leading to the cave. Preferably the break point is surrounded by a frame construction and marked by a snap-off collar. A master valve located beneath the top of the cave is used as a safety valve, protected by an apron (4). A hydraulic line (7) connecting the valve to a pump (8) becomes damaged when the gas pipe head (1) is snapped off and the resulting pressure loss forces the valve to close.
