Description
Technical field
The present invention relates to a kind of blast hole projectile filling and obstruction method, especially surface mining has ground after blasthole is drilled in hole
Lower water is drilled behind hole because of the blast hole projectile filling and obstruction method that are full of in hole of raining during water, belongs to blasting engineering technical field.
Background technology
Blasthole has underground water or is drilled hole rains later, and blasthole easily occurs collapse hole or leads to hole depth not by chip ballast plug-hole
The problem of enough.Blasthole has underground water or is drilled after hole full of water in hole of raining, in the strip emulsion for filling waterproof simultaneously
When, explosive, which can swim in the water surface and not sink under water, causes that explosion generates foundation, blasting flyrock and strip emulsion swim in water
In excessive lead to the problem of of spacing between explosive is made to miss-fire.
When common plugging material such as stemming blocks blasting hole with water, stemming can loosely fall in water, lose the effect of blocking.
Invention content
It is an object of the invention to overcome the deficiencies in the prior art, and a kind of blasting hole with water powder charge and obstruction method are provided,
It solves to have underground water in hole or be drilled behind hole in hole of raining to be full of water, explosive, which swims in the water surface and do not sink under water, causes explosion to produce
Take root bottom, blasting flyrock and strip emulsion floating excessive lead to the problem of of spacing between explosive is made to miss-fire in water.
Technical solution is a kind of blasting hole with water powder charge and obstruction method, including as follows used by realizing the object of the invention
Step：
(1) weight is bound in one end of lining rope with a scale, the lining rope for being banded with weight is put into blasthole, detect blasthole
Depth and pore-forming effect；
(2) strip emulsion is tied up on support bar, support bar is put into blasthole, will by the lining rope for being banded with weight
Support bar is pressed into set depth；
(3) diameter 1cm~1.5cm blindings covering support bar of 0.8kg~1.2kg and strip emulsification are put into blasthole
Explosive then extracts lining rope and weight；
(4) step (2) and/or step (3) are repeated, dynamite charge is completed by the charge constitution of setting；
(5) blasthole is blocked up completely with diameter 1cm~1.5cm blindings after completing dynamite charge.
If it is detected that collapse hole occurs for blasthole or blast hole depth is below standard in step (1), perforations adding is needed so that drilling effect
Fruit meets design requirement.
The weight used in step (1) is cylindrical metal block；Or weight is conical metal block, lining rope is bound in circular cone
The tip of shape metal derby.

If continuous charging structure, then more support bars are connected to total length by adhesive tape in step (2) and are equal to setting
Shot depth, strip emulsion is bound as required on the support bar, by being banded with the lining rope of weight by support bar pressure
Enter set depth, followed by step (3).
If decking, will be supported by being banded with the lining rope of weight after one section of support bar is often placed in step (4)
Item is pressed into set depth, and lining rope is required to be put into diameter 1cm~1.5cm rubbles of 0.8kg~1.2kg in blasthole before extracting
Son.
Compared with prior art, beneficial effects of the present invention are as follows：
1st, blast hole projectile filling and obstruction method provided by the invention tie up strip emulsion is reloaded into blasthole on support bar,
Using support bar as the carrier of strip emulsion, support bar uses pvc pipe piece of the arc length for 1/2~1/8 circumference, will
Pvc pipe is cut into 2~8 pvc pipe pieces, you can meet powder charge demand, pvc pipe surface is smooth and tube wall is thin, and its own
With radian can with blasthole and the shape perfect matching of strip emulsion, convenient for explosive decentralization simultaneously will not blasthole with
Gap is formed between strip emulsion, it is ensured that effect during coupling charging, pvc pipe price is low and is easily obtained in demolition site
, use cost is extremely low, groove is opened up on the side of pvc pipe piece before emulsion binding, for binding strip emulsion
Binding strap card in a groove, it is ensured that strip emulsion lashing location is fixed, and will not be floated up and down with flow, ensure explosion
Effect.
2nd, blast hole projectile filling and obstruction method provided by the invention can be set charge constitution by changing the length of pvc pipe piece
It is set to continuous charging structure, decking structure or multicharge structure；It can be by powder charge knot by the radius for changing pvc pipe piece
Structure is set as coupling charging or Uncoincided charge.
3rd, blast hole projectile filling and obstruction method provided by the invention before dynamite charge in advance using the lining rope for being banded with weight
Blast hole depth and pore-forming effect are detected, if it is detected that collapse hole occurs for blasthole or blast hole depth is below standard, needs perforations adding so that
Drilling effect meets the explosion requirement of setting, and the explosion caused by collapse hole leads to dynamite charge position inaccuracy can be avoided to fail,
Lining rope is with a scale, the practical hole depth of blasthole can be directly acquired by scale, and height of water level in blasthole can be judged according to washmarking,
To formulate best blasting scheme, ensure demolition effect.
4th, blast hole projectile filling and obstruction method provided by the invention it is every placement one section of support bar after by being banded with weight
Lining rope support bar is pressed into set depth, on the one hand play the role of be compacted support bar, on the other hand can be pressed in support bar
It is fixed in fact to obtain the placement depth and real time water level for being compacted support bar in real time by lining rope in the process；Lining rope is equal before extracting
Support bar is covered by diameter 1cm~1.5cm blindings of 0.8kg~1.2kg, is first compacted strip emulsion using blinding
And support bar, then weight is proposed again, avoids proposing that strip emulsion and support bar float again during weight, weight is selected
There is bottom surface to be tied up for plane convenient for compacting strip emulsion and support bar, lining rope for cylindrical metal block or conical metal block
The tip of conical metal block is tied in, convenient for above carrying for weight.
5th, blast hole projectile filling and obstruction method provided by the invention use diameter 1cm~1.5cm blindings as explosive interval
Material and multiple-row blasting material, blinding will not float in water, and in water will not be loose, ensure to block effect.
6th, blast hole projectile filling and obstruction method provided by the invention are easy to operate, and use cost is low, and demolition effect is good；It can solve
Certainly there is underground water in hole or be drilled after hole in hole of raining full of water, explosive swims in the water surface and do not sink during dress strip emulsion
Enter the bottom, and between explosion is caused to generate foundation, blasting flyrock and make in water between explosive because of the floating of strip emulsion
It miss-fires away from excessive lead to the problem of.
