At present, in open-pit mining operations, due to environmental climate or geological conditions, after the drilling rig drills, there is often serious water accumulation in the blasthole. The occurrence of water accumulation makes the rock emulsion explosive unable to sink to the bottom of the hole or the specific position required by the technical requirements due to the buoyancy of the water in the hole, which affects the subsequent charge amount, charge length and packing length, and finally affects the blasting effect or causes. Blasting accident. In the prior art, bamboo poles or wooden sticks are usually used in mines to press the emulsion explosive into the bottom of the hole in sections or in multiple sections, and then quickly fill the hole; Although this method can solve the problem of water accumulation in the hole to a certain extent, it requires a lot of labor, and the charging efficiency is low, and there is a safety risk.

Move to the set position. During the movement of the explosive, the traction rope reliably exerts force and effectively overcomes the buoyancy, so that the explosive can be moved in place conveniently, quickly and accurately, reducing the difficulty of charging and ensuring the accuracy of blasting in the later stage. When charging, loosen the fixing screw 3, and adjust the position of the telescopic link 2 relative to the outer rod 1 according to the diameter of the gun hole 12, so that the outer part of the weight head rubber 4 of the deep water gun hole charging device reaches the buoyant tail rubber 6. The length between the outer parts is larger than the diameter of the blasthole 12. After determining the length, tighten the fixing screw 3, and the traction rope 9 goes around the pulley 8; the operator holds the ends of the traction rope 9 and charges the deep water blasthole Put it into the blasting hole 12, do not pull the ends of the two ends of the traction rope 9 when the charging device of the deep water blasting hole has not reached the designated position; The weight is greater than that of the buoyant tail rubber 6, so the deep-water blasting charge device is always inclined during the descending process. When the deep-water blasting device reaches the designated position, pull both ends of the traction rope 9 upwards at the same time, and pull it slowly and forcefully.

Finally, the charging efficiency is high, the labor intensity of the construction personnel is significantly degraded, and the blasting is accurate in the later stage. meet demand.

The telescopic link 2 is configured to be able to expand and contract relative to the outer rod 1 , and the fixing screw 3 is configured to be able to penetrate the outer rod 1 and contact the telescopic link 2 . The above structure can change the overall length of the deep-water blasthole charging device by adjusting the relative positions of the telescopic link and the outer rod, so that it is suitable for blasting holes of different diameters, and the versatility of the device is improved.

A plurality of protruding counterweight rubber tentacles 10 are arranged on the outside of the weight rubber 4 ; and a plurality of protruding tail rubber tentacles 11 are arranged on the outside of the buoyancy tail rubber 6 . With the above structure, the rubber tentacles can be used in a variety of different types of hole walls and water environments, and can ensure that when the device reliably reaches the designated position, it can be firmly stressed and ensure that the device can play its role normally.

When the deep-water blasting charging device is placed in the blasting hole 12 to install explosives, both ends of the traction rope 9 are set to a structure that can extend to the outside of the blasting hole 12 .

When the counterweight rubber 4 and the buoyancy tail rubber 6 of the described deep-water blasting device are clamped on the inner wall of the blasting hole 12, the outer rod 1 and the telescopic connecting rod 2 of the deep-water blasting charging device are all set to be in an inclined state. structure. In the above structure, in the process of placing the deep-water blasting charging device, since the traction rope itself is eccentrically connected, and the weight of the matching head is greater than that of the buoyant tail rubber 6, the deep-water blasting charging device is always in the descending process. tilted state. When the deep-water blasting device reaches the designated position, pull both ends of the traction rope 9 upward at the same time, and pull slowly and forcefully. The size is larger than the diameter of the blasthole. Therefore, after applying upward pulling force, the deep-water blasting charging device will abut on the inner wall of the blasting hole, so that the counterweight rubber 4 of the deep-water blasting charging device can be easily clamped. On the inner wall of one side of the blast hole 12, the buoyancy tail rubber 6 is clamped on the inner wall of the other side of the blast hole 12, so that the deep water blast hole charging device is positioned with the blast hole 12 and will not be easily separated. With the above structure, after the explosives are loaded in place, the deep-water blasthole charging device does not need to be recovered. Therefore, in use, each deepwater blasthole charge placement is a one-time use. The devices are mostly degradable materials. In this way, it does not affect the work and is easily degraded.
