Disclosed is an emergency rescue shaped charge cutting device with life detection function including a life detection device and a shaped charge cutting device body. The life detection device body is arranged on the inner or outer side of the shaped charge cutting device body. The shaped charge cutting device body includes a protective cover, a shaped charge cutting rope and a fuze system. The shaped charge cutting rope is embedded in the front side of the protective cover, and the detonating end of the fuze system penetrates into the interior of the protective cover from the rear side of the protective cover to be connected to the shaped charge cutting rope. Accordingly, the life detection device may be combined with the shaped charge cutting device to detect living beings and achieve precise blasting, thereby coordinating operation of the two devices and improving rescue efficiency.

The disclosure relates to a shaped charge assembly including a casing and a liner, the liner being a hollow dome forming a hollow space, coaxially arranged around a longitudinal central axis (x) of the shaped charge assembly. The casing and the liner together defines a volume including an explosive. The liner includes an internal surface facing the hollow space and an external surface facing the volume including the explosive. A tangent of the internal surface and a base plane (y) formed at a base end of the liner, the base plane being perpendicular to the longitudinal central axis (x), forms an angle (α) of at least 100°.

The present disclosure relates to a shaped charge. The shaped charge includes an explosive component and a liner member coupled to the explosive component. The explosive component and the liner member emit a perforating jet based on ignition of the explosive component. The liner member has a planar symmetric portion that is planar symmetric along an axial length of the planar symmetric portion relative to planes perpendicular to a direction of the emitted perforating jet.

The present disclosure relates to a shaped charge liner. The shaped charge liner includes a first liner portion formed a first material. The first liner portion has an apex and a skirt section that define an interior volume of the first liner portion. The shaped charge liner also includes a second liner portion formed of a second material. The second liner portion is coupled to the first liner portion such that the second liner portion is an edge of the interior volume.
