The present invention relates to mine blasting technical field, specifically a kind of airspace structure and method 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
It is specifically a kind of for the airspace structure of mine blasting and side the present invention relates to mine blasting technical field
Method.
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.
Summary of the invention
Present invention seek to address that the above problem, so that air can either be completely cut off, can play waterproof action again by providing one kind
The airspace structure and method for mine blasting.
The present invention 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, and the upper end of distance bar is in
Petal-shaped is evenly arranged with multiple support arms, and explosive bag is provided on support arm, is provided in explosive bag for sealing blasthole
The bed of material is sealed, seals and is provided with explosive layer above the bed of material, be provided with buring layer above explosive layer.
Preferably, support arm is arranged four.
Preferably, the sealing bed of material is sandy and stony soil.
A kind of airspace method for mine blasting, includes the following steps:
(1) one end of distance bar is split by the bamboo pole for selecting diameter and blasthole aperture to be adapted as distance bar in petal-shaped
Pintongs constitutes four support arms；
(2) it is filled on four among the distance bar rived support arms using the explosive bag at scene, with adhesive tape by four support arms
Lower part winding, so that distance bar can integrally transfer to blasthole bottom hole；
(3) distance bar made is put into blasthole bottom hole along blasthole angle, and is checked using gage, if do not reached
Blasthole bottom hole continues to transfer distance bar to blasthole bottom hole；
(4) sandy and stony soil is put into the explosive bag along blasthole inner wall on four support arms, between sandy and stony soil is gathered in by self gravity
The sealing bed of material is formed at the top of spacer bar, prevents distance bar periphery from having gap, causes explosive to fall into the bottom water of blasthole hole along gap, keep away
Exempt from explosive waste；
(5) it is put into explosive, detonator on sandy and stony soil along blasthole inner wall, then carries out the blasting procedure such as filling.
The present invention 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, work of the blocking aperture bottom water without influencing demolition effect can be played
With 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 and do not influence quick-fried
Broken effect, construction is simple facilitate work, and construction cost is greatly saved in low manufacture cost.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the embodiment of the present invention；
Fig. 2 is the structural schematic diagram of distance bar of the embodiment of the present invention；
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 invention will be further described, and purpose, which is only that, more fully understands the content of present invention, therefore, institute
The example of act is not intended to limit protection scope of the present invention.
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.
A kind of airspace method for mine blasting, includes the following steps:
(1) bamboo pole for selecting diameter and 1 aperture of blasthole to be adapted rives one end of distance bar 8 in petal-shaped as distance bar 8
At pintongs, four support arms 3 are constituted；
(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 branch
3 lower part of brace 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, if not
1 bottom hole of blasthole is reached, continues to transfer distance bar 8 to 1 bottom hole of blasthole；
(4) it is put into sandy and stony soil in the explosive bag 2 along 1 inner wall of blasthole on four support arms 3, sandy and stony soil is gathered in by self gravity
The sealing bed of material 6 is formed at the top of distance bar 8, prevents 8 periphery of distance bar from having gap, explosive is caused to fall into 1 bottom hole of blasthole along gap
In 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 present invention can play blocking aperture bottom water 9 without shadow when there is a small amount of water 9 in 1 bottom of blasthole and when without waterproof explosive
The effect for ringing demolition effect, ensure that water 9 is isolated with the absolute of explosive, is directly placed into 1 hole of blasthole when 1 bottom hole of blasthole there is not water 9
It plays the role of air-spacer again when bottom, that is, saves explosive and do not influence demolition effect, using bamboo pole as distance bar
8, purchase is convenient, and cheaply, explosive bag 2 is that live residue recycles, low manufacture cost, and flexibility is stronger, construction is simple
Facilitate work, construction cost is greatly saved.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to use equivalence changes made by description of the invention and its accompanying drawing content, it is intended to be included within the scope of the present invention.
