Description

Technical Field

[0001] This utility model belongs to the field of directional blasting devices for mine blasting, specifically, it relates to a directional blasting device for mine blasting. Background Technology

[0002] Directional blasting devices play a crucial role in mine blasting. They significantly improve mining efficiency by allowing blasting energy to break rocks in a predetermined direction and range. For example, in open-pit mines, they can guide ore to a planned location for convenient transportation, reducing secondary handling, saving costs, and ensuring mining safety. They limit the direction of blasting energy diffusion, reducing the risk of damage to surrounding facilities (such as supports and tracks), and minimizing injuries to personnel and equipment caused by blasting vibrations and flying debris. In underground mines, they can also control the stability of the roof and surrounding rock, preventing collapses and optimizing resource utilization. Precise control reduces excessive ore crushing, ensuring ore quality, improving recovery rates, and facilitating subsequent mineral processing. Traditional methods control direction by strategically arranging the position and quantity of explosives and detonators in the blast holes, such as using decoupled charges. Other techniques utilize the shaped charge effect, incorporating shaped charge troughs in the charge structure to concentrate explosive energy in a specific direction. However, these technologies have certain limitations. For example, under complex geological conditions, precise control of the blasting direction remains difficult. It may be affected by rock hardness and joint fissures, causing the blasting effect to deviate from expectations. Moreover, some technologies are costly.

[0003] Existing directional blasting devices used in mine blasting have several problems, such as difficulty in connecting the devices and poor energy focusing performance, which affect blasting efficiency. Therefore, developing a connectable directional blasting device with good energy focusing performance for mine blasting is of significant practical importance. Utility Model Content
