Abstract
The utility model relates to a paper plug for borehole belongs to explosive materials technical field, the cylindrical plug for borehole of plug for borehole for curling and constitute by corrugated container board, the outside circumference curved surface of plug for borehole is provided with a plurality of fasteners that are used for blocking the big gun hole, the utility model discloses utilize the dumped corrugated box preparation that holds detonator or explosive, reduced the blasting cost, simultaneously, the utility model discloses a plug for borehole intensity is big, can be effectively fixes heavier explosive in the big gun hole to can fix positions different in the big gun hole with the explosive.
Description
Technical field
The utility model belongs to explosive technical field, is specifically related to a kind of papery plug for borehole.
Background technology
When on ore deposit, down-hole or subway tunnel carry out blast working, when aperture, big gun hole is downward, adopt the explosive of coupled mode filling very easily to drop out big gun hole, cause big gun hole can not effective fragmentation, cause and owe to dig or other adverse consequences, therefore measure must be adopted effectively to be got lodged in by explosive in big gun hole; Meanwhile, for the big gun hole of Discontinuous charge, need explosive to be fixed on different position, big gun hole; Existing technology is sponge plug for borehole, is made up of high strength sponge, but in engineering reality, on the one hand because sponge plug for borehole needs to prepare in addition, adds blasting cost; On the other hand, because sponge plug for borehole intensity is low, when powder stick is heavier, cannot be fixed on preferably in big gun hole, therefore applies less.
Utility model content
For the deficiencies in the prior art, the utility model proposes a kind of papery plug for borehole, to reach effectively fixing explosive, object that cost is cheaper.
A kind of papery plug for borehole, described plug for borehole is that the outer circumference curved surface of plug for borehole is provided with multiple fastener for blocking big gun hole by the corrugated board curling cylindrical plug for borehole formed.
Described fastener is fish scale-shaped fastener.
The cross section of described plug for borehole is the telescopic spirality of diameter.
The diameter of described plug for borehole is greater than blasthole diameter.
Advantage of the present utility model:
The utility model proposes a kind of papery plug for borehole, the discarded corrugated case holding detonator or explosive is utilized to make, reduce blasting cost, simultaneously, plug for borehole intensity of the present utility model is large, effectively heavier explosive can be fixed in big gun hole, and explosive can be fixed on positions different in big gun hole.
Accompanying drawing explanation
Fig. 1 is the papery plug for borehole structural representation of a kind of embodiment of the utility model;
Fig. 2 is the corrugated board structure schematic diagram of a kind of embodiment of the utility model;
In figure, 1 is fish scale-shaped fastener.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of embodiment of the utility model is described further.
In the present embodiment, employing blasthole diameter is the explosion big gun of 42mm, and explosive need be fixed on bottom big gun hole by explosion;
In the present embodiment, as shown in Figure 1, a kind of papery plug for borehole, described plug for borehole is by the curling cylindrical plug for borehole formed of corrugated board, as shown in Figure 2, the outer circumference curved surface of plug for borehole is provided with multiple fish scale-shaped fastener 1 for blocking big gun hole to the structural representation of described corrugated board; The cross section of described plug for borehole is the telescopic spirality of diameter, and the diameter of plug for borehole is greater than blasthole diameter;
In the present embodiment, tear from the discarded corrugated case holding detonator or explosive and get long 150mm, the corrugated board of wide 100mm rolls into the plug for borehole that diameter is 50mm, and cut out multiple fish scale-shaped fastener 1 for blocking big gun hole at the outer circumference curved surface of plug for borehole, put into explosive in big gun hole after, be 35mm by papery plug for borehole diameter, after putting into big gun hole, the diameter of papery plug for borehole automatically restores to 42mm, with big gun hole interference fit, promoting papery plug for borehole with tamper is fixed to bottom big gun hole by explosive, the fish scale-shaped fastener of papery plug for borehole makes papery plug for borehole and big gun hole inwall fix more firm,
In the present embodiment, the length of papery plug for borehole can be determined according to the actual set position of explosive in big gun hole.
