Description

Technical Field

[0001] The invention relates to the technical field of mine blasting, and in particular to a charging device for underground mine blasting. Background Art

[0002] Mine blasting is a key technology in the mining process. It uses the huge energy released by explosives in an instant to generate high-temperature, high-pressure and high-speed shock waves in the medium around the explosives, thereby destroying the structure of rocks or ore, breaking and loosening them to facilitate subsequent excavation, transportation and other operations. In open-pit mining, various engineering construction, underground deep hole mining, large-scale industrial site leveling and other projects, medium-deep hole blasting has an irreplaceable position and very high technical and economic effects in its application process.

[0003] Ore blasting generally requires charging the blastholes, but the existing charging methods basically use manual plugging to stuff explosives and various auxiliary supplies into the blastholes. The blastholes generally have a certain height. Manual operation is not only time-consuming and labor-intensive, but also because the inner diameter of the blasthole is fixed, smaller explosives cannot fill the entire blasthole, affecting the effect of mine blasting.
