Abstract
Method is blocked the present invention relates to a kind of blasthole open-work, belongs to mining technical field, comprises the following steps：1) selection diameter is more than 100mm Liu Yuanmu；2) Liu Yuanmu is processed and polished to be formed and block round log, the one end for blocking round log is manufactured into pyramidal structure, form tapering point, the other end for blocking round log manufactures cylindrical structural, formation cylindrical end；3) tapering point for blocking round log is filled in the open-work of blasthole, then the cylindrical end for blocking round log is pressed into the open-work of blasthole using weight；4) open-work of blocking round log and blasthole is made to be blocked by being interference fitted；The present invention is easy to use, time saving and energy saving, and blocking effect is good, effectively prevent the generation for sliding phenomenon, and stability is good, practical.
Description
Technical field
Method is blocked the present invention relates to a kind of blasthole open-work, belongs to mining technical field.
Background technology
Mine needs to carry out explosion treatment in recovery process, generally carries out explosion using explosive, when in use, will can fry
Medicine is filled into blasthole, but open-work is offered in blasthole, and when loading explosive, explosive can be escaped to outside blasthole by open-work
Side, not only influences demolition effect, can also cause the waste of explosive, increases blasting cost, in order to solve the above problems, is generally entering
During row explosion, the blocking of open-work can be carried out using carton, woven bag and other items, but fastness is bad, blocking effect is poor, warp
Often slid in blasting process, influence demolition effect.
The content of the invention
According to deficiency of the prior art above, the problem to be solved in the present invention is：A kind of easy to use, time saving province is provided
Power, blocking effect is good, is prevented effectively from generation and slides phenomenon, it is ensured that demolition effect, it is to avoid the blasthole open-work of waste of material blocks method.
The technical solution adopted for the present invention to solve the technical problems is：
Described blasthole open-work blocks method, comprises the following steps：
1) selection diameter is more than 100mm Liu Yuanmu；
2) Liu Yuanmu is processed and polished to be formed and block round log, the tapered knot of one end processing and fabricating of round log will be blocked
Structure, forms tapering point, and the other end for blocking round log manufactures cylindrical structural, forms cylindrical end；
3) tapering point for blocking round log is filled in the open-work of blasthole, the cylindrical end of round log then will be blocked using weight
It is pressed into the open-work of blasthole；
4) open-work of blocking round log and blasthole is made to be blocked by being interference fitted.
Blasthole open-work blocks method and blocked by blocking the interference fit of round log and open-work, fastness and blocking effect
It is good, the leakage of explosive in blasting process can be prevented effectively from, it is to avoid the waste and the increase of cost of material, it is ensured that good
Demolition effect, it is easy to use, it is time saving and energy saving, with stronger practicality.
One end of described blocking round log is set to tapering point, and the other end for blocking round log is set to cylindrical end, taper
End and cylindrical end are structure as a whole.The convenient installation and fixation for blocking round log.
Further preferred, surrounding is that arc seamlessly transits structure at the top of tapering point.
It is further preferred, a diameter of 80mm of tapering point top surface.
It is further preferred, a diameter of 100mm of cylindrical end.
Further preferred, the length for blocking round log is 500mm.
The present invention is had an advantageous effect in that：
Blasthole open-work blocking method of the present invention is easy to use, time saving and energy saving, simple in construction, ensure that the stifled of open-work
Fill in effect good, improve and block fastness, effectively prevent the explosive leakage in blasting process, it is to avoid the waste of material and cost
Increase, good demolition effect is ensure that, with stronger practicality.
Brief description of the drawings
Fig. 1 blocks the structural representation of round log for the present invention；
Fig. 2 is enlarged drawing at Fig. 1 of the present invention A；
In figure, 1, tapering point；2nd, cylindrical end.
Embodiment
Embodiments of the invention are described further below in conjunction with the accompanying drawings：
As shown in Figure 1-2, blasthole open-work of the present invention blocks method, comprises the following steps：
1) selection diameter is more than 100mm Liu Yuanmu；
2) Liu Yuanmu is processed and polished to be formed and block round log, the tapered knot of one end processing and fabricating of round log will be blocked
Structure, forms tapering point 1, and the other end for blocking round log manufactures cylindrical structural, forms cylindrical end 2；
3) tapering point 1 for blocking round log is filled in the open-work of blasthole, the cylinder of round log then will be blocked using weight
End 2 is pressed into the open-work of blasthole；
4) open-work of blocking round log and blasthole is made to be blocked by being interference fitted；
One end of described blocking round log is set to tapering point 1, and the other end for blocking round log is set to cylindrical end 2, bores
Shape end 1 and cylindrical end 2 are structure as a whole.
The described top surrounding of tapering point 1 is that arc seamlessly transits structure, a diameter of 80mm of the top surface of tapering point 1, cylinder
A diameter of 100mm at shape end 2, the length for blocking round log is 500mm.
The present invention is simple in construction, and simple for production, processing cost is low, easy to use, time saving and energy saving, and blocking effect is good, effectively
The generation that tamper in blasting process slides phenomenon is avoided, demolition effect is ensure that, it is to avoid the waste of explosive, saves into
This, with stronger practicality.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the legend with description.
