Abstract

See full text

The present invention discloses a charging device and method for open pit mine rock perforation blasting within the mining technology domain. The charging device includes a charging barrel with a detachable cover plate at the top and a bottom opening, housing a tray for explosive material. A jacking mechanism on the tray's side surface aids in positioning. A flexible interval gasbag separates the explosive and tray, with a wire passing hole at its center connected to an air pump via an inflation tube. A pressing plate and lifting mechanism in the cover plate facilitate lifting within the barrel. Additionally, a moving mechanism on the blast hole's top relocates the charging barrel. This innovation addresses challenges related to the cumbersome positioning and filling of existing powder explosives in open pit mine rock perforation blasting.
