Description

Technical Field

[0001] This utility model relates to open-pit blasting technology, specifically an auxiliary device for filling explosives into blast holes in open-pit blasting. Background Technology

[0002] Chinese patent document CN116839436A discloses a device for fixing and filling blast holes in open-pit blasting. It addresses the issue that in existing open-pit blasting, blast holes are opened on the mountain surface. After explosives are filled into the holes, they are typically sealed with multiple layers of stones taken from the site. A baffle is then placed at the blast hole opening to complete the open-pit blast. However, during open-pit blasting operations, improper baffle placement can cause the sealing stones to splatter out of the blast hole after the explosives detonate, posing safety hazards around the blast hole. Furthermore, damage to the baffle hinders its reuse and increases the cost of open-pit blasting. The solution proposed is to easily install and remove the baffle and baffle posts from the fixing device. When the baffle and baffle posts are damaged, they can be easily replaced promptly, improving the efficiency of the fixing device. The combination of the baffle and spring allows the baffle to limit the stones during sealing, ensuring a tighter seal. When stones splatter, the spring effectively cushions the baffle, further improving its efficiency.

[0003] When the above-mentioned schemes and existing technologies are used to fill explosives into open-pit blasting holes, which are generally several meters to more than ten meters deep, the explosive charge is prone to collision with the hole wall due to the roughness of the hole wall when it is placed in the hole by its own weight. This can cause the packaging film to break and block the hole. During use, this will lead to discontinuous loading of explosives into the blasting hole, affecting the construction progress and blasting effect. In severe cases, it may even cause misfires, which cannot meet the actual use requirements.

[0004] Therefore, this utility model proposes an auxiliary device for filling explosives into open-pit blasting boreholes to solve the above-mentioned problems. Utility Model Content
