Technical Field
[0001] The invention relates to the technical field of charge cartridges, in particular to an open-pit mine blasting charge device and method. Background Art
[0002] In open-pit mine blasting operations, the charging device is a key equipment to ensure blasting effect and operation safety. Traditional charging methods often have problems such as complex operation, easy leakage of explosives, and unstable fixing of charging cartridges, which bring considerable safety hazards to blasting operations. In order to solve these problems, a variety of improved charging devices have appeared on the market, but there are still some shortcomings.

During the charging process, the lid of the charging cartridge needs to be opened and closed frequently, which is cumbersome and easy to cause explosive leakage. In addition, after the charging cartridge is placed in the charge hole, there is often a lack of effective limiting measures, which is easy to be displaced or overturned due to external factors (such as wind, vibration, etc.), thus affecting the blasting effect and operation safety.

Load the explosive: Dial the sleeve and rotate it around the cartridge case as the central axis until the through opening of the sleeve is opposite to the guiding inlet of the cartridge case. Put the emulsion explosive into the cartridge case through the through opening and the guiding inlet. Then rotate the sleeve again to misalign the through opening and the guiding inlet to close the opening of the cartridge case and prevent the explosive from leaking.
