Description

Technical Field

[0001] The present invention belongs to the technical field of gas rock breaking, blasting and other equipment, and relates to a porous biomass granular adsorption combustion agent.

Background Art

[0002] Liquid oxygen-biomass green high-energy instantaneous rock-breaking technology is based on the principle of utilizing the chemical reaction of liquid oxygen and carbon-based materials and the phase change expansion of liquid gas. Liquid oxygen and charcoal are put together to explode, releasing carbon dioxide and carbon monoxide, thereby achieving the purpose of killing bombs. Compared with traditional explosive blasting technology, this technology is safe, economical, green and low-carbon, and easy to construct.

[0003] Based on the application principle of this technology, some specific blasting structures have also emerged. For example, the Chinese invention patent with application date of December 16, 2021 and publication number CN114184090A provides an in-hole flexible fracturing device and its use method. This application uses a flexible membrane sleeve to replace the ordinary fracturing outer tube to avoid unsafe phenomena such as flying tubes and unexploded tubes; and the flexible membrane sleeve is not a traditional tubular shape. Before filling the fuel core, its shape can be folded or compressed into any shape. It becomes tubular only after the fuel core is filled. There is no transportation problem at all, and there is no safety hazard.
