[0002] With the rapid mechanization of vertical shaft mining, smooth blasting is vigorously promoted in the construction of rock shafts to create more favorable conditions for one-time tunneling. The bedrock section construction method of the vertical shaft adopts a mixed operation method of "one digging and one laying": drilling, charging, and blasting to remove the gangue to the flat bottom, and then pour concrete.
