Description

technical field [0001] The invention belongs to the technical field of blasting engineering, and in particular relates to a tree root removal device for blasting blastholes in dangerous rock masses. Background technique [0002] Dangerous rock mass means that when the rock mass is suspended and has obvious cracks, there is a risk of collapse at any time, so it has a major safety hazard. Because the terrain of the dangerous rock mass is relatively complicated, most of them are on uneven slopes and cliffs. Therefore, blasting is usually used to remove the dangerous rock mass. Since trees, vines and other plants usually grow around the dangerous rock mass and on the body, the roots of the plants will drill into the cracks of the dangerous rock mass, and the tree roots will affect the drilling. , and when the emulsion explosive is loaded into the blasthole, it will be stuck, and the explosive will not be filled at the bottom of the hole, which will seriously affect the blasting ...

[0002] Dangerous rock mass means that when the rock mass is suspended and has obvious cracks, there is a risk of collapse at any time, so it has a major safety hazard. Because the terrain of the dangerous rock mass is relatively complicated, most of them are on uneven slopes and cliffs. Therefore, blasting is usually used to remove the dangerous rock mass. Since trees, vines and other plants usually grow around the dangerous rock mass and on the body, the roots of the plants will drill into the cracks of the dangerous rock mass, and the tree roots will affect the drilling. , and when the emulsion explosive is loaded into the blast hole, it will be stuck, and the explosive will not be filled at the bottom of the hole, which will seriously affect the blasting effect. Therefore, we propose a device for removing tree roots in the blast hole of dangerous rock
