Abstract
The utility model provides a mining hole blocking stopper, the device includes the cement cock body, and the outer wall of cock body is equipped with the elasticity sealing washer, and the external diameter of elasticity sealing washer is 1.5-2 times of big gun hole internal diameter, and the internal diameter is 0.8-0.9 times of cock body external diameter. The utility model provides a because the jam quality in cement cock body and pore wall clearance is not good, lead to a large amount of hourglass down of loose sand, the blasting effect receives the problem of influence. The bowl-shaped elastic sealing ring is additionally arranged on the outer wall of the cement plug body, so that the blocking quality of a gap between the cement plug body and a hole wall is improved, the blocking procedure of the gap between the cement plug body and the hole wall is saved, the time is saved, and the blasting effect is optimized.
Description
Technical field
The utility model belongs to the technical field of mine blasting blasthole, and in particular to a kind of mining hole plug.
Background technology
Plug-hole operation is important step in surface mine bench blasting and underground mine VCR mining codes.Traditional plug-hole work
Work will generally be that the prefabricated conical cement cock body for being hung in nylon rope tail end is transferred to hole, then transfer the plastics for being underfilled with river sand
Bag blocks cement cock body and hole wall gap, then blocks up dress loose sand into hole again to predetermined altitude, but in real work,
The method causes loose sand lower leakage in a large number, demolition effect to be affected often because cement cock body is not good with the blocking quality in hole wall gap.
Utility model content
The purpose of this utility model is to provide a kind of mining hole plug, to solve prior art due to cement cock body and hole wall
The blocking quality in gap is not good, causes loose sand lower leakage in a large number, the affected problem of demolition effect.
To solve the above problems, the technical solution adopted in the utility model is：
A kind of mining hole plug, including cement cock body, the outer wall of cock body are provided with elastic seal ring, the external diameter of elastic seal ring
For 1.5-2 times of blasthole internal diameter, internal diameter is 0.8-0.9 times of cock body external diameter.
For the utility model is better achieved, elastic seal ring is bowl-type.
For the utility model is better achieved, the rim of a bowl of elastic seal ring is opening up.
For the utility model is better achieved, the rim of a bowl of elastic seal ring is crenation.
For the utility model is better achieved, elastic seal ring is located at the 1/4-3/4 of cock body.
For the utility model is better achieved, elastic seal ring thickness is not less than 1cm.
The utility model is had the advantages that compared to prior art：The mining hole plug that the utility model is provided
Bowl-type elastic seal ring is set up in the external wall of cement plug, the blocking quality of cement cock body and hole wall gap is not only increased, and
Cement cock body and the stifled operation of the bag in hole wall gap are saved, the time is saved, and is optimized the effect of explosion.
Description of the drawings
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure top view of the present utility model.
Reference implication is as follows：1st, cock body；2nd, elastic seal ring；3rd, blasthole；4th, the rim of a bowl.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of mining hole plug, including cock body 1 as shown in Figure 1-2, is provided with elasticity close at the 1/4-3/4 of the outer wall of cock body 1
Seal 2, elastic seal ring 2 are bowl-type, and the rim of a bowl 4 is opening up, and the rim of a bowl 4 is crenation, and the external diameter of elastic seal ring 2 is blasthole
1.5-2 times of 3 internal diameters, 0.8-0.9 times for 1 external diameter of cock body of internal diameter, thickness is not less than 1cm.
Before plug-hole operation, elastic seal ring 2 is enclosed within 1 outer wall 1/4-3/4 of cement cock body, due to elastic seal ring 2
0.8-0.9 times for 1 external diameter of cement cock body of internal diameter, using elastic 1 outer wall of clamping cement plug body of elastic seal ring.
During plug-hole operation, mining hole plug is hung in blasthole 3 with lifting rope, transferred to the precalculated position of top board aperture
At 30-50cm, as the external diameter of elastic seal ring 2 is 1.5-2 times of 3 internal diameter of blasthole, using elastic seal ring 2 elasticity by its
Great thrust is produced to 3 inwall of blasthole, 2 external diameter of elastic seal ring and the 3 internal diameter clamping of blasthole of mining hole plug, Ran Houshang is made
Hole plug is carried to precalculated position, in drawing process, 2 external diameter of elastic seal ring and 3 wall of blasthole occur friction, as frictional resistance makes
Turn under the rim of a bowl 4, overturn as the rim of a bowl 4 upward down by the rim of a bowl 4, and be close to 3 inwall of blasthole, so as to reach the carrying energy of needs
Power.
After the plug-hole end of job, appropriate river sand is inserted by design requirement on mining hole plug, and carry out bursting work.
