The digital electronic detonator hole-by-hole detonating network comprises 4-8 rows of blast holes arranged in parallel, according to the arrangement of each row of blast holes, the row distance is 3.3-3.8 m, the hole distance of each row of blast holes is 4.8-5.5 m, the number of the blast holes in the first row is 10-25, the number of the blast holes in each rear row is one less than that of the blast holes in the front row, and the total number of the blast holes is 34-172; the diameter of the blast hole is 90-100 mm, the inclination angle is 70-80 degrees, and the depth is 12-17 m; and each blast hole is internally provided with a millisecond delay electric detonator. According to the digital electronic detonator hole-by-hole detonating network and the blasting delay scheme thereof, in actual use, the material pile throwing distance can be increased in the blasting operation process, the boulder rate is reduced, the foundation rate is reduced, the production cost is reduced, and meanwhile the blasting effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of blasting, in particular to a hole-by-hole initiation network of digital electronic detonators and a blasting delay scheme thereof. Background technique [0002] The detonator is the main detonating material in blasting engineering. Its function is to generate detonating energy to detonate various explosives, detonating cords and detonating tubes. Electronic detonators, also known as digital electronic detonators, digital detonators or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process. With the development of blasting technology, high-precision digital electronic detonators have been effectively applied. Digital electronic detonators are mainly used for hole-by-hole detonation in mine blasting. Through different delay settings, each digital electronic detonator in the blast hole is set, and then the sequence between the ...
