The invention relates to an extremely short-range blasting construction vibration absorbing method and a vibration absorbing and energy gathering lancing cartridge. During the construction of a tunnel and a vertical shaft, a blasthole is drilled in a working face and filled with an explosive, and blasting is carried out near the existing building at an extremely short-range. One group of large hollow holes are drilled at one side, close to the existing building, of the working face, a vibration absorbing blasthole is drilled between every two adjacent large hollow holes, the vibration absorbing blastholes are charged with vibration absorbing and energy gathering lancing cartridges, and the vibration absorbing and energy gathering lancing cartridges are lancing cartridges concentrating explosion energy in the directions of the large hollow holes on the two sides. Millisecond detonator tubes are connected with the charged blastholes. Blasting is carried out in several times, the vibration absorbing blastholes are blast first, and then, other blastholes are blast. The extremely short-range blasting construction vibration absorbing method has the advantages that when the blasting construction of an urban subway is carried out extremely close to the existing line or building, the blasting vibration velocity can be effectively controlled, the influence of blasting vibration on the existing tunnel is reduced, and the maximum blasting vibration velocity is reduced by as high as 60% in comparison with that of the traditional blasting technical solution.
