Abstract
The utility model relates to mine blasting technical field, specifically a kind of airspace structure for mine blasting.Including blasthole, distance bar is provided in blasthole, the upper end of distance bar is evenly arranged with multiple support arms in petal-shaped, explosive bag is provided on support arm, it is provided with the sealing bed of material for sealing blasthole in explosive bag, seals and is provided with explosive layer above the bed of material, be provided with buring layer above explosive layer.When there is a small amount of water in blasthole bottom and when without waterproof explosive, it can play the role of blocking aperture bottom water without influencing demolition effect, when bottom hole there is not water and is directly placed into bottom hole, it plays the role of air-spacer, it saves explosive and does not influence demolition effect, construction is simple facilitates work, construction cost is greatly saved in low manufacture cost.
Description
Technical field
The utility model relates to mine blasting technical field, specifically a kind of airspace structure for mine blasting.
Background technique
At present in bursting work work progress, it is frequently utilized that the airspace that polybag and compressed gas are made
Device, there are the problem of include: since misoperation or product quality problem are easy the position among blasthole and expand, especially
It is difficult to handle if blocking among blasthole when deep hole blasting, that there is also relative costs is higher for the air-spacer in addition sold,
And sale businessman is less, the defects of delivery cycle is longer, and when blasthole bottom hole has a small amount of water and when without waterproof explosive, greatly
Affect demolition effect.
Utility model content
The utility model aims to solve the problem that the above problem, so that air can either be completely cut off, can play waterproof again by providing one kind
The airspace structure for mine blasting of effect.
The utility model solves described problem, the technical solution adopted is that:
A kind of airspace structure for mine blasting, including blasthole, are provided with distance bar in blasthole, distance bar it is upper
End is evenly arranged with multiple support arms in petal-shaped, and explosive bag is provided on support arm, is provided in explosive bag for sealing big gun
The sealing bed of material in hole seals and is provided with explosive layer above the bed of material, is provided with buring layer above explosive layer.
The utility model by adopting the above technical scheme, compared with prior art, the feature protruded is:
When there is a small amount of water in blasthole bottom and when without waterproof explosive, blocking aperture bottom water can be played without influencing demolition effect
Effect, when bottom hole there is not water and is directly placed into bottom hole, it plays the role of air-spacer, that is, saves explosive not shadow again
Demolition effect is rung, construction is simple facilitates work, and structure is simple, and construction cost is greatly saved in low manufacture cost.
Preferably, the further technical solution of the utility model is:
Support arm is arranged four.
The sealing bed of material is sandy and stony soil.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram；
Fig. 2 is the structural schematic diagram of the utility model embodiment distance bar；
Fig. 3 is the overlooking structure diagram of Fig. 2；
In figure: blasthole 1；Explosive bag 2；Support arm 3；Buring layer 4；Explosive layer 5；Seal the bed of material 6；Adhesive tape 7；Distance bar 8；Water
9。
Specific embodiment:
Below with reference to embodiment, the utility model is described in further detail, and purpose, which is only that, more fully understands the utility model
Content, therefore, the cited case are not intended to limit the protection scope of the utility model.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of airspace structure for mine blasting, including blasthole 1, the interior setting of blasthole 1
There is distance bar 8, the upper end of distance bar 8 is in support arm 3 there are four petal-shaped is uniformly arranged, it is provided with explosive bag 2 on support arm 3,
It is provided with the sealing bed of material 6 for sealing blasthole 1 in explosive bag 2, seals and is provided with explosive layer 5 above the bed of material 6, on explosive layer 5
Face is provided with buring layer 4.
Construction method:
(1) one end of distance bar 8 is in petal-shaped as distance bar 8 by the bamboo pole for selecting diameter and 1 aperture of blasthole to be adapted
It is split into pintongs, constitutes four support arms 3；
(2) it is filled in using the explosive bag 2 at scene on four support arms 3 among the distance bar 8 rived, with adhesive tape 7 by four
A 3 lower part of support arm winding, so that distance bar 8 is whole can to transfer to 1 bottom hole of blasthole；
(3) distance bar 8 made is put into 1 bottom hole of blasthole along 1 angle of blasthole, and is checked using gage, such as
Fruit does not reach 1 bottom hole of blasthole, continues to transfer distance bar 8 to 1 bottom hole of blasthole；
(4) sandy and stony soil is put into the explosive bag 2 along 1 inner wall of blasthole on four support arms 3, sandy and stony soil is poly- by self gravity
Collect and form the sealing bed of material 6 on the top of distance bar 8, prevents 8 periphery of distance bar from having gap, explosive is caused to fall into blasthole 1 along gap
In hole bottom water 9, explosive is avoided to waste；
(5) it is put into explosive, detonator on sandy and stony soil along 1 inner wall of blasthole, then carries out the blasting procedure such as filling.
The utility model when there is a small amount of water 9 in 1 bottom of blasthole and when without waterproof explosive, blocking aperture bottom water 9 can be played and
The effect for not influencing demolition effect ensure that water 9 is isolated with the absolute of explosive, be directly placed into blasthole when 1 bottom hole of blasthole there is not water 9
It plays the role of air-spacer again when 1 bottom hole, that is, saves explosive and do not influence demolition effect, using bamboo pole as interval
Bar 8, purchase is convenient, and cheaply, explosive bag 2 is that live residue recycles, low manufacture cost, and flexibility is stronger, construction letter
Folk prescription is just made, and construction cost is greatly saved.
The above is only the preferred feasible embodiment of the utility model, not thereby limits to the power of the utility model
Sharp range, it is all with equivalence changes made by the utility model specification and its accompanying drawing content, it is both contained in the utility model
Within interest field.
