Explosive charging structure for ultra-deep hole blasting

The utility model provides an ultra-deep hole blasting charging structure, which belongs to the technical field of ground ultra-deep hole blasting equipment and comprises a multi-section charging mechanism, and the multi-section charging mechanism comprises a plurality of hoses, charging column barrels and detonating cords penetrating through the charging column barrels and the hoses. A first sealing block and a second sealing block are arranged at the upper end opening position and the lower end opening position of each charging column barrel respectively, and annular connecting pieces are arranged at the two ends of a hose matched with each charging column barrel. According to the invention, all the cartridges are mutually restrained and connected in the process of putting the cartridges, so that the situation that the subsequent charging is influenced due to the fact that a certain cartridge is clamped in a certain place in a hole is effectively avoided, the cartridges are ensured to fall at a pre-planned
