The invention relates to the field of ammunition manufacturing and engineering blasting. An integrated scattering type oriented explosion cylinder is composed of a cylinder body, an end cover and an ignition device, wherein a cavity of the cylinder body is filled with explosives, and the ignition device is led out of a hole in the end cover. Conical or semicircular pits which are formed in rows and in lines and distributed in a regular or irregular mode are formed in the outer circumferential face of the tubular cylinder body, wherein the central axes of the pits are perpendicular to the longitudinal axis of the tubular cylinder body, the distance, along the longitudinal axis of the cylinder body, between the central axes of every two adjacent pits ranges from 1 cm to 50 cm, and protrusions in the corresponding shapes are formed in the inner wall face of the cylinder body through the pits. The cone vertex angle of the conical pits ranges from 30 degrees to 160 degrees, the length of the generatrix of the conical pits ranges from 0.5 cm to 20 cm, and the diameter of the bottom face of the conical pits is 2 to 50 times of the thickness of the wall of the cylinder body. The radius of the semicircular pits is 2 to 50 times of the thickness of the wall of the cylinder body. After the explosives are blasted, high-temperature and high-pressure detonation waves act on the pits, and high-speed jet flow is formed through extrusion drive. The integrated scattering type oriented explosion cylinder is simple in manufacturing process, low in cost and capable of being applied to the tunnel cutting blasting occasion, the presplitting blasting occasion and other occasions.
