Description

Technical Field

[0001] This utility model relates to the field of underground safety protection technology in coal mines, specifically a two-stage carbon monoxide elimination device for underground drilling and blasting in coal mines. Background Technology

[0002] In underground blasting operations in coal mines, the detonation of water-based explosives generates a large amount of carbon monoxide gas. Traditional methods rely on ventilation systems for passive dilution, which suffers from problems such as reaction lag and incomplete treatment of dead zones. Existing devices often employ a design where the reactant container is separate from the blasting unit, resulting in complex installation and difficulty in achieving rapid response. Furthermore, insufficient reliability of the fixed structure can easily lead to device displacement, affecting the efficiency of carbon monoxide removal. Utility Model Content

[0003] The purpose of this invention is to provide a two-stage carbon monoxide elimination device for underground drilling and blasting in coal mines, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a two-stage carbon monoxide reaction elimination device for underground drilling and blasting in coal mines, comprising: a mining water-gel explosive, a carbon monoxide reactant, a primary container, a secondary container, a sealing cap, and a connecting pipe. One end of the primary container is sealed, and the other end has an internal sleeve. The mining water-gel explosive is placed inside the sleeve, and the carbon monoxide reactant is placed outside the sleeve. The lead wire of the mining water-gel explosive is passed through the lead wire opening of the secondary container. The carbon monoxide reactant is placed in the secondary container, and the lead wire of the mining water-gel explosive is passed through the lead wire opening of the sealing cap. The connecting pipe is passed through the secondary container, and the embedded nut is tightened. After the sealing process is completed, the explosive is detonated. After the primary and secondary containers rupture simultaneously, the carbon monoxide reacts actively with the carbon monoxide in both containers.

[0005] Preferably, the primary container, secondary container, sealing cap, and connecting pipe are connected by threads.

[0006] Preferably, the secondary container and the sealing cap have a lead-in port at one end near the connecting pipe.

[0007] Preferably, the built-in sleeve and secondary container contain carbon monoxide reactant.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] After blasting with water-based explosives in the mine, the carbon monoxide reacts with the carbon monoxide in the inner sleeve and secondary container at high temperature, converting it into carbon dioxide. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Please see Figures 1 to 3 This utility model provides a technical solution: a two-stage carbon monoxide reaction elimination device for underground drilling and blasting in coal mines, comprising: a mining water-gel explosive 1, a carbon monoxide reactant 2, a primary container 3, a secondary container 5, and a connecting pipe 9. One end of the primary container 3 is sealed, and the other end has an internal sleeve 4. The mining water-gel explosive 1 is placed inside the internal sleeve 4, and the carbon monoxide reactant 2 is placed outside the internal sleeve 4. The lead wire of the mining water-gel explosive is passed through the lead wire opening 6 of the secondary container 5. The carbon monoxide reactant 2 is placed in the secondary container 6, and the lead wire of the mining water-gel explosive is passed through the lead wire opening 6 of the sealing cover 7. The connecting pipe 9 is passed through the secondary container 5, and the embedded nut 8 is tightened. After the sealing process is completed, the explosive is detonated. After the primary container 3 and the secondary container 5 explode simultaneously, the carbon monoxide reacts actively with the carbon monoxide in both containers.

[0014] When this device is in operation, during mining operations, after deep hole blasting, toxic and harmful gases will enter the working face through the cracks, which will pose a great threat to the life safety of people working in the mine. The harmful gas is mainly carbon monoxide. By placing the assembled device in the rock borehole, after the mine water gel explosive 1 is detonated, the carbon monoxide reactant 2 in the inner sleeve 4 and the secondary container 5 reacts with carbon monoxide at high temperature and is converted into carbon dioxide.
