Technical Field
[0001] The invention relates to the technical field of open-air blasting charging, and in particular to an open-air blasting deep-water hole charging device and a use method thereof. Background Art
[0002] Existing open-pit mining mostly uses perforation blasting to loosen steps. During the step blasting process, deep water holes appear due to groundwater or weather. There are many ways to deal with deep water holes, such as pumping water, or using mixed emulsions and finished emulsion explosives for blasting. Finished emulsions are widely used in deep water hole treatment. Now, two direct methods are used: directly throwing finished emulsion explosives into the blasthole and using hooks for lifting. However, when the finished emulsion explosives are loaded into the deep water hole, their density is similar to or even smaller than that of water, so they are not easy to sink. The explosives are easy to float in the water. Therefore, the loading process is slow and it is easy to cause blockage of the hole, and the discontinuity of the explosives causes blind shots and other problems. Summary of the invention
