Abstract
A method and system for neutralizing mines has a vehicle carrying fluid connected to a pump and cavitation pressure vessel that creates high pressure fluid. An actuator valve modifies the flow characteristics of the high pressure fluid to be pulsating at selectively different frequencies, pressures, and flow rate. Nozzles on the vehicle jet high pressure fluid therethrough and a framework on the vehicle orients the nozzles to direct the jetted flow of high pressure fluid downward and into ground under a roadway. An abrasive and/or explosive can be added to the high pressure fluid before it reaches the nozzles. The jetted flow from the nozzles can displace ground and exert pressure to detonate and cut mines and neutralize them on and under the roadway. Cavitation can be created in the jetted flow to increase the dynamic force of the jetted flow.
