Problems solved by technology

Since the rock-breaking effect is the best when detonating from the bottom of the hole, the plastic detonating tube is used to insert the emulsion explosive roll to detonate the explosive, and the plastic detonating tube is directly used to transfer the explosive into the bottom of the blast hole. At this time, the plastic detonating tube is easy to mix with the emulsion explosive The roll falls off, and even the plastic detonating tube is thinned or even broken, causing the detonating tube to fail, and the explosive cannot be detonated normally

Abstract

The invention discloses a device and a method for filling an open-air large-diameter blast hole with emulsion explosive, and belongs to the field of blasting. The device for filling the open-air large-diameter blast hole with emulsion explosive comprises a telescopic rod which is at least partially hollow and is provided with a round hole; a circular ring is fixed at one end of the telescopic rod; a plurality of claws are used for clamping the explosive and are rotationally connected to the circular ring; and a pull rope penetrates into the round hole, and a plurality of branches which are fixedly connected with the claws respectively are formed at the tail end of the pull rope.

Description

technical field [0001] The invention relates to the field of blasting, in particular to a device and method for filling emulsion explosives in large-diameter blastholes in the open air. Background technique [0002] When charging the blast hole with a deep open air and a relatively large diameter, the emulsion explosive loaded has a larger diameter and a heavier weight of the emulsion explosive. Since the rock-breaking effect is the best by blasting from the bottom of the hole, insert the emulsion explosive roll to detonate the explosive with a plastic detonator, and directly transfer the explosive to the bottom of the blast hole with the plastic detonator. At this time, the plastic detonator is easy to mix with the emulsion explosive The roll falls off, and even the plastic detonating tube is thinned or even broken, causing the detonating tube to fail, and the explosive cannot be detonated normally. In order to pack the emulsified explosive with larger diameter and heavier...
