Blasting multi-branch network connecting method

Abstract

The invention discloses a blasting multi-branch network connecting method. The connecting method comprises the following steps: averagely dividing a to-be-blast area into a plurality of sub blast areas; arranging multiple groups of detonators at the inner layer of a blasting area of each sub blast area for blasting, wherein each group of detonators comprises electronic detonators and nonel detonators, and the blasting area accounts for 3/5 to 4/5 of the corresponding sub blast area; at a starting point of the blasting area, detonating by the nonel detonators; stimulating the electronic detonator at the starting point by the detonated nonel detonators; and sequentially detonating the rest groups of detonators to blast after the electronic detonator at the starting point is detonated. According to the blasting multi-branch network connecting method provided by the invention, each group of detonators comprises the electronic detonators and the nonel detonators, the electronic detonator blasting network is simple, a buckle only needs to block onto a connecting wire, and the whole network adopts a parallel-connecting way, so that operations are simple. The blasting multi-branch networkconnecting method changes a network way of only using the nonel detonators in the conventional blasting way, adopts a composite network way, is small in control errors, and is simple to operate.

Description

Technical field [0001] The invention relates to the technical field of building blasting and demolition, in particular to a blasting compound network connection method. Background technique [0002] In cities, the blasting demolition of tall buildings (structures) often requires the safe and reliable detonation of thousands of detonators at a time. Electric detonation networks, detonator detonator detonation networks, and electronic detonation networks each have their own advantages. Disadvantages and applicable conditions. 1. From the perspective of network design requirements: a large-scale electric detonator detonation network requires that each electric detonator can obtain sufficient current, and the construction organization and arrangement of the network connection, the distribution and voltage division of the network, etc. have strict requirements ; Nonel detonator detonation network, there is no network shunt, partial pressure and detonation energy design requirements, ...
