[0016] A deep hole blasting device suitable for eliminating carbon monoxide according to the utility model will be described below in conjunction with the accompanying drawings.

[0017] In the first embodiment of the present application, Figures 1 to 3As shown, a deep hole blasting device suitable for eliminating carbon monoxide comprises a coal wall 1, a carbon monoxide elimination component 2, an external elimination agent diffusion part 2-1, an elimination agent 2-11, a limiting plate 2-12, an explosive column 2-13, a detonating wire 2-14, a detonator 2-15, an elimination agent diffusion part 2-2 in the hole, an elimination agent shell 2-21, an elimination agent 2-22, a connecting screw hole 2-23, an initiating part 2-3, an initiating explosive 2-31, a detonator 2-32, an explosive column 3 and a blasting hole 4. The blasting hole 4 is opened on the coal wall 1, and the explosive column 3 is inserted into the inner side of the blasting hole 4 and then blocked with the carbon monoxide elimination component 2. The explosive column 3 can be adjusted according to the filling quantity as needed. The carbon monoxide elimination component 2 also includes an external eliminator diffusion part 2-1, an in-hole eliminator diffusion part 2-2 and an initiating part 2-3. The two ends of the in-hole eliminator diffusion part 2-2 are respectively screwed to the external eliminator diffusion part 2-1 and the initiating part 2-3 through connecting screw holes 2-23. The cylindrical eliminator shell 2-21 wraps the eliminator 2-22; the initiating part 2-3 has built-in detonating explosive 2-31 and detonator 1 2-32. The disc-shaped external eliminator diffusion part 2-1 shell is filled with eliminator 1 2-11. The explosive column 2-13 is installed at the central axis of the round cake-shaped eliminator 1 2-11. The explosive column 2-13 is equipped with a detonator 2-15. The initiating wire 2-14 is respectively connected to the detonator 1 2-32 and the detonator 2-15 through wires.

[0018] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 4 As shown, the external eliminator diffusion part 2-1 is fixedly installed with a limit plate 2-12 on the opposite side of the eliminator diffusion part 2-2 in the hole. The limit plate 2-12 can further shape the cloud of the eliminator 1 2-11 into a disc shape after the detonator 2-15 detonates the explosive column 2-13, so as to more effectively absorb the carbon monoxide in the coal seam.

[0019] In order to further optimize the working efficiency of the present application and prevent the second eliminater 2-22 from getting damp, the described eliminater housing 2-21 is made of oil paper and lined with nylon mesh. In order to achieve a better CO elimination effect, the eliminaters in the described eliminater 2-22 and the eliminater 1 2-11 are prepared from low-cost metal oxides, with a particle size of 120 meshes, and the amount of the eliminater in the eliminater 2-22 is 60g, and the amount of the eliminater in the eliminater 1 2-11 is 25g. In order to reduce production costs, the described limit plate 2-12 is made of engineering plastics.

[0020] When in use, the utility model is installed with the explosive column 3 into the pre-set deep hole, and finally connected with the corresponding detonation circuit.

[0021] When the utility model is in use, the specific operations are as follows:

[0022] During detonation, the explosive column 2-13, the explosive column 3 and the detonating part 2-3 are detonated simultaneously. The explosive column 3 and the detonating part 2-3 will flush out the eliminator 2-22, mix it with the blasted coal wall, and eliminate the carbon monoxide produced deep in the coal wall during blasting. The explosive column 2-13 will spread the eliminator 2-11 in a disc shape, covering the surface of the coal wall, and effectively eliminating the carbon monoxide produced on the surface and deep in the coal wall.

[0023] In summary, the deep hole blasting device suitable for eliminating carbon monoxide in the embodiment of the utility model can directly eliminate carbon monoxide during blasting by arranging the eliminator 2-22 and the eliminator 2-11 at the outer end and the opening of the blasting hole and through the umbrella-shaped eliminator cloud after blasting, thereby effectively improving the safety of the working surface.

[0024] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
