ABSTRACT The invention relates to a new method of using explosives. In the past it was the practise to use the shock wave front or the pressure pulse, or both, generated by a detonated explosive mass to directly affect a target or to deform and drive a solids element against the target. In the method proposed by the present invention the explosive mass (11) and a compressible focussing means (12) are supported in a liquid medium. The focussing means (12) lie between the explosive mass and the target (T) and is spaced therefrom by liquid medium. The compressible focussing means (12) may comprise a compressible solids material or a gas volume. When the explosive mass (11) is detonated the pressure pulse, and the liquid displaced by the gas bubble generated by the detonation, serve to collapse the focussing means (12), generating high pressure liquid flows directed towards the target (T).
