[0002] Deep hole blasting is a blasting technology with a borehole diameter greater than 50mm and a hole depth greater than 5m. This technology is widely used in open-pit and underground excavation projects, and has achieved good technical and economic results. The drilling forms of deep hole blasting are mainly divided into vertical deep holes and inclined deep holes. When installing explosives, the explosives are installed on protective covers and then installed on bamboo at a fixed distance. However, this installation method requires carrying a large amount of auxiliary construction materials. For example, if more than 100 blasting holes are required, 100 bamboos are required, plus at least 300 protective covers, which requires dump trucks to transport more than ten times and the construction area is relatively complex, resulting in very high labor intensity for blasting workers.
