Abrégé

The present invention refers to an improved invention that is foldable, antistatic with partial compressibility, semi-flexible, thin-walled, with components, which can serve as water insulation, soil stabilizer, continuous extension regardless of the length and even in cases of caverns and/or geological faults, which allows for cushioned blasting by decoupling the hole and which is used in blasting processes in the extraction of minerals, by placing a container in a natural borehole. The improved invention allows containers as long as required, facilitating transport, providing continuity, the main feature is that it is folded and unfolded, without affecting the shape or functionality of the same when used in drilling and for long containers facilitates transport, storage and handling. In addition, it allows easy loading of the explosive despite the presence of water, cracks, geological faults, previous mining and/or loose ground; it also avoids obstructions or “falls” caused by vibrations during the drilling process or by ground movements caused by nearby blasting, obtaining a clean, continuous, dry and stable borehole, which guarantees maximum advance and avoids costly rework; allowing the explosive to be dosed using a smaller diameter container and a spacer and anchor ring to form an air chamber between the wall to be protected and to generate a mitigated blast between the wall to be protected, obtaining firm ceilings and/or walls. In addition, in long downward holes, the explosive can remain self-supporting by means of a crossbar or shutter, which protects it from being blocked by transit of people or vehicles; In addition, in long ascending boreholes, they can provide continuity and allow to carry any explosive, stopping it even when loaded for more than 8 weeks, finally eliminating the risk of accumulation of static charges and avoiding the possibility of accidents since these charges can activate the explosives.

Abrégé

The present invention relates to a semi-flexible, anti-static, folding container which can be partially compressed, said container having accessories and comprising a thin wall allowing buffer blasting operations, decoupling the bore hole, suitable for use in mineral extraction processes. As a result of the invention, containers can be as long as required, since transport, storage and handling are facilitated owing to the fact that the container can be folded and unfolded without its form or function being impacted. In addition, the explosive can be easily loaded and dosed using a container of smaller diameter and an anchoring spacer ring in order to form an air chamber and generate buffer blasting. The container of the invention can also be self-supported by means of a crossbar or a closure member.
