Abstract

The invention discloses a solid carbon dioxide fracturing device and method; the device is used for being mounted in a blast hole to blast a substratum to be blasted; the device comprises a solid carbon dioxide storage tube, two ends of the solid carbon dioxide storage tube are sealed, a heating tube is passed through the solid carbon dioxide storage tube and is filled with a heating agent, a cavity between the heating tube and the solid carbon dioxide storage tube is used for filling with solid carbon dioxide, the heating tube is also connected to a detonating device through a detonating circuit, and allowable pressure of material for the solid carbon dioxide storage tube is less than 10 Mpa. Small tensile strength of the solid carbon dioxide storage tube can be provided, most low-price materials in the market, such as plastic or paperboard, can be adapted to, and the fracturing device is greatly lower in device cost and usage cost than a fracturing device prepared with high-pressure-tolerant metal material; since these low-price materials are light in weight, it is convenient for workers to move or assemble the fracturing device and labor generation efficiency is improved accordingly.

Description

technical field

[0001] The invention relates to the technical field of mine blasting, and more specifically relates to a dry ice carbon dioxide cracking device and a cracking method. Background technique

[0002] refer to figure 1 As shown, the existing carbon dioxide explosion / explosion system is composed of a carbon dioxide cracker 201 (with a safety heating tube inside), a carbon dioxide inflation workstation 202, and a liquid carbon dioxide 203. Specifically, liquid carbon dioxide is compressed and charged into the carbon dioxide cracker by using a carbon dioxide inflating workstation at the construction site, and then the carbon dioxide cracker 201 is loaded into the blast hole, and the detonator 204 is used for detonation.

[0003] When detonating at the construction site, the detonator quickly ignites the heating tube in the carbon dioxide cracker, and the heating tube generates heat, which provides heat to quickly heat the liquid carbon dioxide with a pressure of 10...
