Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts all belongs to
In the scope of protection of the utility model.
Fig. 1 to Fig. 3 shows the structural schematic diagram of one preferred embodiment of the utility model, a kind of deep hole in Fig. 1
Standing device, including demolition set, explosion propagation device and hole sealing device, explosion propagation device one end connect demolition set, the other end
Even initiator 8, hole sealing device to drilling orifice block (such as shown in Figure 1, the hole sealing device can be use water filling
Pouch 6, by water filling port 7 in water filling pouch 6 water filling pressurization carry out sealing of hole) and middle part pass through explosion propagation device.As shown in Figure 1,
The demolition set is mainly made of big gun head 1, powder chamber 2 and energy-gathering ring 3, big gun head 1 make destructor coal wall drilling in more
Good advance, for being filled with explosive, install energy-gathering ring 3 in 2 bottom of powder chamber prevents outside explosion energy the inner cavity in the middle part of powder chamber
It lets out, big gun head 1 is connected to the front end of powder chamber 2, and there is diameter contraction mouth, energy-gathering ring 3 to be mounted on diameter for the rear end inner cavity of powder chamber 2
At the step formed between 2 inner cavity of contraction mouth and powder chamber, the copper of energy-gathering ring 3, iron or aluminium are made in oblate cylindricality, and middle part is provided with
Aperture is passed through for big gun line 5；As shown in Fig. 2, the explosion propagation device includes the drug delivery detonator 4 and big gun of antiknock high temperature resistant material
The antiknock high temperature resistant material of line 5, drug delivery detonator 4 can select PPA plastics (also referred to as high temperature resistant nylon, heat distortion temperature
Up to 300 DEG C or more, continuous use temperature up to 170 DEG C can meet needed for short-term and long-term hot property) or metal and
The mixture etc. of plastics makes drug delivery detonator 4 have certain tension resistance, can be wound in a ring when drug delivery detonator 4 is flat,
It can be stretched when work and send demolition set to pre- quick-fried place, 4 one end of drug delivery detonator is installed by the way of being threadedly coupled
At the diameter contraction mouth of powder chamber 2, the other end is located at drilling orifice or drilling orifice outside, the connection detonation of 5 one end of big gun line
