Background
The surface mining operation mainly comprises the processes of perforation, blasting, loading, transportation, dumping and the like, and the blasting is a technology for achieving the expected purpose by utilizing the compression, loosening, destruction, throwing and killing effects generated by the explosion of explosives in air, water, earth and stone media or objects. When the explosive package or explosive charge explodes in the earth and stone medium or the structure, the earth and stone medium or the structure generates the phenomena of compression, deformation, damage, loosening and throwing, and the explosive package or explosive charge is mainly used for earth and stone engineering, the demolition of metal buildings and structures and the like; the blast hole is filled with mixed explosives, and the detonating bombs are simultaneously fed into the hole to perform reverse detonating at the bottom of the blast hole; the mixed explosive is required to resist the self weight of the explosive and the driving force of the explosive after foaming in the hole by depending on the viscosity of the explosive and the internal friction force of the hole wall. And gravitational potential energy exists at the bottom of the hole for arranging the detonating bullet; when the mixed charge is conveyed in the hole by the charge pipe, the mixed charge which is not foamed completely can not be completely bonded with the hole wall, and the mixed charge is totally returned out of the hole under the influence of the dead weight of the detonation bomb. It is more difficult to reload the mixed explosive.
Therefore, a filling method for mixing explosives and initiating explosive in an upward blasting hole is provided.
