As shown in Figure 1, embodiment 1: Large diameter deep-hole blasting charge constitution, it include blasthole 9, oil emulsion pack 4, lead it is quick-fried
Rope 6, detonator 7 and detonator 8, the blasthole is interior to be connected with hole plug 1 compatible with blasthole internal diameter by steel wire 2, described stifled
Bottom fine sand layer 3, the bottom fine sand layer top are filled in blasthole of the stopple above the bottom of blasthole, the hole plug
Pack and bamboo 5 are intervally distributed with to blasthole top-direction, and the mode that is spaced apart of pack and bamboo is every two layers of pack interval
One layer of bamboo, the length of bamboo are 0.7m.Top fine sand layer 10 is filled at the top of the blasthole, above the top fine sand layer
Detonator 7 is laid in blasthole, the blasthole top is externally provided with detonator 8, and the detonator is connect with detonator, and the detonator connects
It is connected to the primacord 6 for extending downwardly across top fine sand layer and connecting with each pack, one end of primacord 6 is tied up into a medicine
It is a big gun head on packet 4.Primacord has two, is passed down through top fine sand layer from detonator extraction and connects with every pack,
Pack above the fine sand layer of bottom can be referred to as bottom pack, which has two layers, be located under the fine sand layer of top
The pack of side can be referred to as top pack, remaining pack can be referred to as middle part pack, and top pack has two layers, middle part medicine
Packet is two layers, and top pack can be referred to as cut spreader hole from 2m at the top of blasthole, the blasthole of this structure.
As shown in Fig. 2, embodiment 2: the difference from embodiment 1 is that the mode that is spaced apart of pack and bamboo is bottom medicine
It is surrounded by two layers, top pack and middle part pack are one layer, and the length of the bamboo is 0.7m, near the pack of top fine sand layer
Apart from 1.5m at the top of blasthole, the blasthole of this structure can be referred to as interstitial hole.As shown in figure 3, embodiment 3: with embodiment 1
Difference is that the mode that is spaced apart of pack and bamboo is that bottom pack has two layers, and top pack and middle part pack are one layer, institute
The length for stating bamboo is 1m, and apart from 2m at the top of blasthole, the blasthole of this structure can be referred to as the pack near top fine sand layer
For periphery hole.
The medicine layer in blasthole 9 in the utility model is ignited by double primacords 6 and double detonator 7.With intermediate pore structure
For blasthole, the installation process of the utility model is as follows: first transferring at away from bottom hole 0.5m hole plug 1 with iron wire 2, is used in combination
Iron wire 2 is fixed by hole plug 1, and bottom fine sand layer 0.5m is then filled out in blasthole 9；One end of primacord 6 is tied up into a pack 4
Upper is a big gun head, two big gun heads is continuously transferred in hole to bottom hole, at aperture that primacord 6 is fixed, primacord 6 has
The effect of primer 4 is avoided that the defect that every layer of pack 4 is ignited with detonator 7, such as powder charge using 6 primer 4 of primacord
Structure is cumbersome, charging quality requires high, detonation stability difference etc.；The bamboo 5 of a 0.7m long is transferred with the rope with hook,
