Abstract

The invention discloses an on-site mixed emulsion explosive charging device and method for tunnel peripheral holes. The charging device comprises a charging sleeve, a sleeve sealing piece and an elastic fixing ring. The charging sleeve extends from the bottom of the blast hole to the opening of the blast hole, the sleeve sealing piece seals the opening, located at the bottom of the blast hole, of the charging sleeve, the elastic fixing ring is arranged at the opening of the blast hole and clamped between the periphery of the charging sleeve and the wall of the blast hole, and the charging sleeve is used for containing a detonator, a detonating charge and on-site mixed emulsion explosives. The charging method is implemented on the basis of on-site mixed charging equipment and the device, and low-density explosives are filled. The device has the beneficial effects that the charging device is simple in structure, convenient to manufacture and mount on site, capable of forming non-coupling charging, labor-saving, low in labor intensity and high in construction efficiency, and hole net parameter optimization for enlarging the hole diameter of a blast hole is facilitated. The charging method is implemented on the basis of on-site mixed charging equipment and the charging device, and the smooth blasting effect is ensured through combination of the low-density explosive and the non-coupling charging structure.

Description

technical field [0001] The invention relates to engineering blasting technology, in particular to a device and a method for on-site mixed-packed emulsion explosives for tunnel peripheral holes. Background technique [0002] Most of the procedures in tunnel construction projects have been mechanized, but the blasting operation still mainly adopts manual loading and packaging of explosives. The manual charge blasting method of traditional packaged explosives is mainly manifested in that the packaging of packaged explosives and the loading of blastholes are mostly done manually, resulting in high labor intensity, high operating intensity and low construction efficiency, which seriously restricts the smooth progress of large-scale tunnel construction. Compared with the traditional blasting operation method of packaged explosives, the new technology of on-site mixed explosives adopts mixed vehicles to mix on-site and directly output them into the blasthole, which has the advantag...
