Abstract

The invention discloses a non-primary hole-by-hole blasting surface detonator and a mounting and using method thereof, and relates to the technical field of engineering blasting. The non-primary hole-by-hole blasting surface detonator comprises a tube body, an inner cape, low-energy explosives, a delay element, a plastic connecting stopper and detonating tubes, wherein the inner cap, the low-energy explosives, the delay element and the plastic connecting stopper are arranged into the inner part of the tube body in sequence; and the detonating tubes are arranged into the plastic connecting stopper. According to the detonator, the delay element is ignited by two detonating tubes to stimulate the low-energy explosives in the inner cap to blast so as to detonate four detonating tubes which are inserted into the bottom of the inner cap of the tube body from the outlet of the tube body; two shock tube detonators in blast holes are detonated by two detonating tubes, and a hole-by-hole blasting surface detonator in a next blast hole is detonated by another two detonating tubes, thereby realizing hole-by-hole blasting in this way. The detonator is simple in structure, free of primary explosive, low in explosive amount, low in cost, safe to produce and use, and reliable to detonate and transfer detonation, so that the problems that a surface detonator in the prior art is high in cost and dangerous to produce and use are solved.

Description

Technical field: [0001] The invention relates to the technical field of engineering blasting, in particular to a hole-by-hole priming surface detonator without priming charge and an installation and use method thereof. Background technique: [0002] With the continuous development of engineering blasting technology and the continuous improvement of blasting technology, the amount of one-time blasting increases, and the requirements for the performance, accuracy, and energy consumption of blasting products are also getting higher and higher, especially with the modernization of drilling machinery , the diameter of each blast hole is large, generally Φ70-140mm, and the drilling depth is also deep, generally more than 15m. The charge of a single blast hole is large. The amount of blasting is very large, and even the total amount of explosives in one blast can reach tens of tons to thousands of tons. Such blasting produces large vibrations, which will have a greater impact or da...
