Description

Explosive cartridge filling structure, explosive method and explosive device Technical Field The invention belongs to the technical field of smooth blasting, and particularly relates to a blasting cartridge filling structure, a blasting method and a blasting device. Background At present, the explosive used for smooth blasting is usually a colloidal emulsion explosive with small diameter, discontinuous charge is adopted in a blast hole, the explosive support and the explosive support are connected by bamboo chips, and the explosive support is bound on the bamboo chips. In order to stabilize detonation, detonating cords are used for detonating between the medicine branches. In the blasting process, the explosive branch, the bamboo chips, the detonating cord and the detonator are required to be combined on the blasting site, and if the blasting engineering quantity is large, a large amount of time is consumed in the combination process, so that the engineering progress is influenced. In addition, the detonating cord is high in price, so that the light explosion cost is high. In smooth blasting, an energy collecting tube is often used, and the energy collecting tube is a core charging and energy collecting device for realizing accurate directional blasting and contour forming control by peripheral holes (contour holes). Particularly, when the uncoupled charging structure is adopted, the risk of decentration and direction disorder of the charging can be reduced by combining the energy collecting tube. After the energy collecting pipe is placed in the blast hole, the orientation of the energy collecting groove of the energy collecting pipe needs to be accurately fixed, so that the concentrated release of blasting energy along the design direction is ensured. The existing common practice is to wind a plastic foam tape on the outer wall of the energy collecting pipe, and fill a gap between the energy collecting pipe and the inner wall of the blast hole by using the foam tape, so that the positioning and the posture fixing of the energy collecting pipe in the blast hole are realized. However, the mode has the obvious defects that in the process of inserting the energy collecting pipe into the blast hole, the plastic foam adhesive tape is easy to rub and pull with the hole wall to be damaged and fall off, the gap is difficult to continuously and stably fill, and finally the position of the energy collecting pipe and the orientation of the energy collecting groove cannot be reliably fixed, so that the smooth blasting effect is affected. Disclosure of Invention Based on the problems in the prior art, the invention aims to provide a explosive cartridge loading structure, a blasting method and a blasting device, so as to reduce the blasting cost and improve the blasting effect.
