The invention provides a system for breaching a lane in a minefield containing pressure sensitive mines. A mobile carrier mounts fuel, nitrogen and water tanks, a hose magazine and a launch rail. A flexible hose is folded into the magazine for rapid deployment therefrom and carries a detonating cord therein. A tow vehicle, such as a rocket, is connected to the free end of the hose so that when it is launched it will pull the hose across the minefield. Thereafter, pressurized nitrogen is used to drive liquid fuel into the hose, followed by a slug of water between the fuel-containing section and the carrier. Detonation of the cord creates a fuel droplets-in-air-cloud above the hose, which cloud is subsequently detonated to create a pressure wave which, in turn, detonates or neutralizes the mines along the desired lane, allowing vehicles and personnel to travel therealong. Means are provided to space the detonating cord from the inner wall of the hose so as to prevent the formation of hot spots as the cord detonates, which hot spots could result in premature local deflagration of the fuel droplet-air cloud.

A method of breaching a safe lane through a minefield containing pressure sensitive mines comprising the steps of: (a) deploying a length of flexible hose across the minefield, said hose carrying a small diameter cord of explosive material therein and therealong; (b) filling a substantial portion of said hose laying on the minefield with a liquid fuel; (c) detonating said cord to create a cloud of fuel droplets-in-air above said minefield along a line defined by said hose portion; and (d) thereafter detonating said cloud to create a pressure wave which detonates or neutralizes the mines along said lane.
