[0002] In the process of mining, when encountering hard rock roof or faults, deep hole blasting operations are usually required to meet the on-site operation needs. During deep hole blasting operations, the CO toxic gas produced will also be discharged into the tunnel, which can easily cause the CO concentration in the tunnel after the blast to be too high, which will pose a serious threat to the workers in the tunnel. At present, local ventilation measures are conventional disposal measures for eliminating CO. Local ventilation mainly uses local ventilators and wind pipes to supply air to the working face to achieve the purpose of diluting CO.

At the same time, part of the dust is taken away by the droplets of part of the CO elimination slurry to achieve synchronous dust reduction operation.
[0005] As a preference, the number of the CO elimination slurry rolls in the first CO elimination tube and the second CO elimination tube are both 1 to 3.
[0006] Furthermore, in order to effectively reduce the amount of CO eliminator used, and at the same time, to improve the CO elimination effect and elimination efficiency, and also to enable the formed CO elimination slurry to have a certain dust reduction effect, the CO elimination slurry in the CO elimination slurry roll is composed of a CO eliminator, an adhesive, a surfactant and deionized water; based on the total mass of the CO elimination slurry, the mass concentration of the CO eliminator is 5-20%, the CO eliminator is a transition metal oxide composed of one or more elements of iron, manganese and cerium, and its particle size is 0.01-0.1 mm, the mass concentration of the adhesive is 7-28%, and the mass concentration of the surfactant is 0.0001%-0.04%.
[0007] As a preferred embodiment, the charge tube bodies in the first CO elimination tube and the second CO elimination tube are both made of flame retardant material in one piece; the energy-gathering tube body is made of flame retardant material in one piece; and the anti-impact structure is made of hard metal material with good corrosion resistance and pressure resistance.
[0008] As a preferred embodiment, in step 2 S21, the upward non-return mechanism is made of a hard metal material with good corrosion resistance and pressure resistance.
[0009] As a preference, the charge tube bodies in the first CO elimination tube and the second CO elimination tube are 1 / 6 to 1 / 4 of the length of the energy-focusing tube body. In the present invention, for the CO elimination component used, a plurality of energy-gathering holes are provided on the energy-gathering tube body, which can facilitate the directional blasting operation. Two anti-skid mechanisms are installed at both ends of the energy-gathering tube body, and two limit structures can be formed at the two open ends of the energy-gathering tube body by using the two anti-skid mechanisms, thereby preventing the explosive roll from falling out of any open end. The anti-skid mechanism is composed of a hard skeleton located inside and a flexible layer located outside, and the hard skeleton is an annular hollow skeleton, which can facilitate the smooth passage of the gun line connected to the explosive roll while playing a limiting role, and at the same time, it can also facilitate the impact force after the explosion of the explosive to act on the charge tube smoothly through the anti-skid mechanism. The fastener is composed of a reduced diameter section located in the middle section and a sleeve section located at both ends, which can facilitate the use of the two sleeve ends at both ends to cover the charge tube and the energy-gathering tube, and at the same time, the reduced diameter section can be used to form a limit structure for the ends of the charge tube and the energy-gathering tube. One end of the charge tube body is opened, and a CO elimination slurry roll and an anti-collision structure are loaded therein to form a charge tube. Then, the open end of the charge tube is inserted into the interior of the fastener, so that a CO elimination section can be formed in the lateral direction of the multi-section explosive roll, which can ensure that the CO elimination slurry in the CO elimination slurry roll is eliminated under the high temperature and high pressure conditions generated by the blasting of the explosives. The anti-collision mechanism is composed of a head end support plate, a terminal support plate and a plurality of elastic components, so that the anti-collision mechanism has a good buffering capacity, and then provides a certain buffering capacity for the CO elimination slurry roll in the charge tube during the explosion process, which is conducive to avoiding the situation where the CO elimination slurry roll is pushed away by the impact force at the beginning of the explosion, and is conducive to the CO elimination slurry roll being torn at the moment of the explosion, and further conducive to the high temperature and high pressure conditions generated by the explosion to quickly evaporate the CO elimination slurry, so that it can be in full contact with the generated CO gas in time, and achieve the purpose of efficient CO elimination. By installing two CO elimination components at the two ends of the energy-gathering tube relative to each other through two fasteners, the generated CO can be efficiently eliminated from both sides on the basis of reducing the amount of CO elimination agent used. In this way, the CO elimination effect is greatly improved on the premise of having the ability to eliminate CO in situ. Furthermore, the droplet-shaped CO elimination slurry can also help to take away part of the generated dust, so that the smoke elimination effect is achieved. By installing an upward check mechanism at the end of multiple blasting units, it is convenient to position the multi-section blasting units after loading, so as to avoid the CO elimination component from detaching from the blast hole. The explosive blasting section in the blast hole forms multiple blasting units of the first CO elimination tube-energy-gathering tube-second CO elimination tube. In this way, two CO elimination sections can be formed on both sides of the multi-section explosive roll in each CO elimination component, and then the generated CO can be effectively eliminated in sections during the blasting process, and the generated dust can have a certain smoke elimination effect, achieving the effect of in-situ CO elimination and smoke elimination in the blast hole to a certain extent.
[0010] In the present invention, multiple CO elimination components are assembled inside the prefabricated blasting hole, and each CO elimination component is arranged in the manner of a first CO elimination tube-energy-gathering tube (with multiple sections of explosive rolls built in)-second CO elimination tube. This unique structure can be used to synchronously eliminate the CO gas and dust generated during the blasting process. At the same time, the elimination efficiency and elimination effect can be greatly improved by eliminating the CO and dust generated during the operation in sections. The upward check mechanism is loaded at the end of the multiple CO elimination components, so that the upward check mechanism can be used to limit the multiple CO elimination components, and the CO elimination components can be prevented from being separated from the blasthole during the loading process. The implementation process of this method is simple, and it can achieve the purpose of eliminating the toxic and harmful CO gas generated by deep hole blasting operations from the source. At the same time, it can also achieve the purpose of synchronous dust reduction. While improving the operating efficiency, it also effectively ensures the safety of workers' lives and health.

The fastener is composed of a reduced diameter section located in the middle section and a sleeve section located at both ends, which can facilitate the use of the two sleeve ends at both ends to cover the charge tube and the energy-gathering tube, and at the same time, the reduced diameter section can be used to form a limit structure for the ends of the charge tube and the energy-gathering tube. One end of the charge tube body is opened, and a CO elimination slurry roll and an anti-collision structure are loaded therein to form a charge tube. Then, the open end of the charge tube is inserted into the interior of the fastener, so that a CO elimination section can be formed in the lateral direction of the multi-section explosive roll, which can ensure that the CO elimination slurry in the CO elimination slurry roll is eliminated under the high temperature and high pressure conditions generated by the blasting of the explosives. The anti-collision mechanism is composed of a head end support plate, a terminal support plate and a plurality of elastic components, so that the anti-collision mechanism has a good buffering capacity, and then provides a certain buffering capacity for the CO elimination slurry roll in the charge tube during the explosion process, which is conducive to avoiding the situation where the CO elimination slurry roll is pushed away by the impact force at the beginning of the explosion, and is conducive to the CO elimination slurry roll being torn at the moment of the explosion, and further conducive to the high temperature and high pressure conditions generated by the explosion to quickly evaporate the CO elimination slurry, so that it can be in full contact with the generated CO gas in time, and achieve the purpose of efficient CO elimination. By installing two CO elimination components at the two ends of the energy-gathering tube relative to each other through two fasteners, the generated CO can be efficiently eliminated from both sides on the basis of reducing the amount of CO elimination agent used. In this way, the CO elimination effect is greatly improved on the premise of having the ability to eliminate CO in situ. Furthermore, the droplet-shaped CO elimination slurry can also help to take away part of the generated dust, so that the smoke elimination effect is achieved. By installing an upward check mechanism at the end of multiple blasting units, it is convenient to position the multi-section blasting units after loading, so as to avoid the CO elimination component from detaching from the blast hole. The explosive blasting section in the blast hole forms multiple blasting units of the first CO elimination tube-energy-gathering tube-second CO elimination tube. In this way, two CO elimination sections can be formed on both sides of the multi-section explosive roll in each CO elimination component, and then the generated CO can be effectively eliminated in sections during the blasting process, and the generated dust can have a certain smoke elimination effect, achieving the effect of in-situ CO elimination and smoke elimination in the blast hole to a certain extent.
[0022] In the present invention, multiple CO elimination components are assembled inside the prefabricated blasting hole, and each CO elimination component is arranged in the manner of a first CO elimination tube-energy-gathering tube (with multiple sections of explosive rolls built in)-second CO elimination tube. This unique structure can be used to synchronously eliminate the CO gas and dust generated during the blasting process. At the same time, the elimination efficiency and elimination effect can be greatly improved by eliminating the CO and dust generated during the operation in sections. The upward check mechanism is loaded at the end of the multiple CO elimination components, so that the upward check mechanism can be used to limit the multiple CO elimination components, and the CO elimination components can be prevented from being separated from the blasthole during the loading process. The implementation process of this method is simple, and it can achieve the purpose of eliminating the toxic and harmful CO gas generated by deep hole blasting operations from the source. At the same time, it can also achieve the purpose of synchronous dust reduction. While improving the operating efficiency, it also effectively ensures the safety of workers' lives and health.
