Description

Technical Field

[0001] This utility model relates to the field of blasting technology in mining, specifically a high-precision directional blasting device for mining. Background Technology

[0002] The main purpose of mine blasting is to blast ore and rock to ensure the normal progress of ore mining. In the process of the development of mine blasting technology, the explosives used in mine blasting are also constantly evolving, such as black powder, nitroglycerin explosives, ammonium nitrate powder explosives, ammonium nitrate explosives, slurry explosives, and emulsion explosives.

[0003] However, existing blasting devices involve simply drilling holes and then inserting explosives, which is unsafe and can easily cause injuries.

[0004] To address the aforementioned deficiencies, Chinese Patent No. CN219572845U discloses a blasting positioning device for mining operations. This device includes a support block, a first arc-shaped clamping plate fixedly connected to the upper surface of the support block, a first fixing block fixedly connected to the side surface of the first arc-shaped clamping plate, a bolt threaded into the inner part of the first fixing block, a second fixing block threaded into the outer surface of the bolt and located above the first fixing block, a second arc-shaped clamping plate fixedly connected to the side surface of the second fixing block, a first spring fixedly connected inside the second arc-shaped clamping plate, and an upper inner layer fixedly connected to the end of the first spring away from the second arc-shaped clamping plate. An inner layer is provided between the upper and lower arc-shaped clamping plates to hold and protect explosives. The design of the spring and the upper inner layer allows it to accommodate explosives of different sizes. Simultaneously, the combination of the spring, limiting pin, and movable column on the base increases the stability of the blasting device in the soil, preventing displacement or falling.

[0005] The aforementioned device utilizes upper and lower arc-shaped clamps to enhance the protection of the equipment during use. However, in some inclined or vertical blast holes, the blasting tube itself may shift or even slip during the explosion, making it difficult to fix. Therefore, in actual use, the blasting tube may shift, leading to a decrease in accuracy. Summary of the Invention
