    摘要: An annular shaped-charge and blasting housing and a use method thereof are provided. The annular shaped-charge and blasting housing includes a PVC segment and multiple notch grooves. Grooves are notched on a W-shaped PVC segment formed by machining. The notching angle of the groove and the spacing distance between the grooves can be adjusted according to use requirements. And, the W-shaped PVC segment after being cut may not be limited to have eight notch grooves, and the number of the notch grooves of a single one PVC segment can be adjusted according to actual working conditions. The PVC segment can be folded and closed to form the annular shaped-charge and blasting housing. Therefore, the housing of the embodiments is simple in production, the linear segment can be bended and folded by utilizing the plasticity of the PVC material. The manufacturing process of the housing is simple and feasible. The housing of the embodiments is convenient to use and can meet the requirements of the annular shaped-charge cutting in blasting engineering. Meanwhile, the housing of the embodiments are widely applied. Further, the housing is not only applicable to annular shaped-charge cutting for the bottoms of holes to improve the planeness of the tunnel faces or the berm for the bench blasting, but also applicable to the cut blasting to improve the cut effect.

    摘要: What is presented is a combustible pellet for creating heated gas. The combustible pellet is insertable into a cutting apparatus or a high power igniter or both. The combustible pellet is compacted to be resistant to mechanical damage and is resistant to unintentional ignition. The combustible pellet is ignitable without a loose powdered form of combustible material when the combustible pellet is in the cutting apparatus or the high power igniter.

    摘要: This invention is a shaped explosive device with a liner that has a parabolic apex, which can produce a purely planar symmetric jet. The half pipe liner in the present invention has a parabolic apex or pole toward the aft end, a “V” notch on each side of the concave wings toward the fore end, and liner base end on each wing. Liner resembles two angled half sections of thin walled pipe butted together at the apex or pole, and when properly driven by a high explosive will produce a spade shaped stretching Munroe jet that erodes a deep elongated hole in a target. Alternatively, this invention is a shaped explosive device with a liner that produces a single combination jet consisting of a forward rod portion and rearward flattened spade shaped portion, this jet has a velocity gradient form tip to tail. When applied in a circular or other polygonal shaped array the Axilinear shaped charges will produce extremely large diameter holes greater than the overall diameter of the array.

    摘要: This invention is a shaped explosive device with a liner that produces a single combination jet consisting of a forward rod portion and rearward flattened spade shaped portion, this jet has a velocity gradient form tip to tail. The jet produced by the shaped charge is axisymmetric for the forward rod portion and planar symmetric for the aft wide spade portion somewhat like linear shaped charge, thusly termed the “Axi-Linear” shaped charge. The forward rod portion of each jet erodes a round hole in the target followed by the aft flattened spade portion of the jet creating a long slotted deep cavity centered on the round hole and in the lateral direction of the spade jet.

    摘要: A method for generating a projectile using an explosive device that can generate a projectile from the opposite side of a wall from the side where the explosive device is detonated. The projectile can be generated without breaching the wall of the structure or container. The device can optionally open an aperture in a solid wall of a structure or a container and form a high-kinetic-energy projectile from the portion of the wall removed to create the aperture.
