Background

In mining, blasting technology is the main mining technology, and the function of blasting technology is extremely key. In the prior open-pit mining, a deep hole blasting method is generally adopted. In deep hole blasting, in order to ensure the blasting effect, a large amount of explosive is generally buried. When the amount of explosive to be buried is large, it is common to fill the explosive layer by layer using spacers. The layered filling of the explosive needs layered detonation, and each layer needs to be provided with an initiating explosive bag. In a common explosive filling technology, an initiating explosive charge provided with a detonator is usually thrown into a blast hole, and the detonator is easy to fall off by adopting the method, so that detonation is influenced, and safety accidents occur in subsequent processes. In addition, by adopting the operation method, the explosive falls too fast and impacts the bottom explosive, so that the density of the bottom explosive is too high, the blasting impact distribution is not uniform, and the blasting effect is influenced.
