Abstract: This disclosure concerns an explosive device, such as a mine, which comprises a flexible enclosure having a pair of separate chambers formed therein. Substantially non-explosive liquids, which when mixed form a liquid explosive material, are respectively disposed in the chambers in separated relation to each other. A closure member is initially disposed so as to block an opening which provides communication between the chambers. Upon removing a latch mechanism holding the closure member in place,the closure member is moved away from the opening to permit mixing of the non-explosive liquids, thereby forming the liquid explosive material and arming the explosive device. A pressure-responsive igniter mechanism is disposed within the enclosure so as to be subject to the pressure condition of the liquid explosive material.
