[0036] Example 1
[0037] like Figures 1-3 As shown, a medium-deep hole blasting test device includes a stand 1 and a blasting hole 2, etc.
[0038] The test platform 1 includes a frame structure 10, a first-level platform 11, a second-level platform 12, and a top platform 13. The frame structure 10 serves as the main load-bearing component and can be a steel frame or similar structure. The first-level platform 11, the second-level platform 12, and the top platform 13 are all fixedly connected to the frame structure 10. Each of these platforms is scalable, allowing personnel to climb onto them using ladders or similar structures to perform operations such as loading and detonating explosives. The first-level platform 11, the second-level platform 12, and the top platform 13 are arranged sequentially from bottom to top, making it suitable for loading and detonating explosives in different areas of the blasting holes 2, facilitating the testing of different blasting schemes.
[0039] In an optional embodiment, the first platform 11, the second platform 12, and the top platform 13 are welded to the frame structure 10, thereby ensuring that each platform has sufficient structural stability and is conducive to the safety of the operator.
[0040] The blasting holes 2 include a central blasting hole 20, a first-zone blasting hole 21, a second-zone blasting hole 22, a top blasting hole 23, and an outer contour blasting hole 24. By setting the central blasting hole 20, the first-zone blasting hole 21, the second-zone blasting hole 22, the top blasting hole 23, and the outer contour blasting hole 24, multiple blasting zones at different locations can be formed, facilitating zoned blasting and enabling testing of various blasting schemes. The central blasting hole 20 is located at the central axis 3 of the tunnel face, and is situated in the middle of either the first-zone blasting hole 21 or the second-zone blasting hole 22. The first-zone blasting hole 21, the second-zone blasting hole 22, and the top blasting hole 23 are arranged sequentially from bottom to top. The first zone blasting hole 21 includes a first left-side blasting hole 211 and a first right-side blasting hole 212, which are symmetrically arranged on both sides of the central axis 3 of the tunnel face. The second zone blasting hole 22 includes a second left-side blasting hole 221 and a second right-side blasting hole 222, which are also symmetrically arranged on both sides of the central axis 3 of the tunnel face. The top blasting hole 23 includes at least two groups of holes spaced apart, each group of holes being arranged in an arc shape. The outer contour blasting hole 24 is located at the outer contour line 4 of the tunnel face.
[0041] In an optional embodiment, the height of the first platform 11 is located between the first zone blast hole 21 and the second zone blast hole 22, that is, the second zone blast hole 22 is located above the first platform 11, and the first zone blast hole 21 is located below the first platform 11. Therefore, workers can stand on the ground to perform operations such as loading and detonating explosives at the first zone blast hole 21, and can stand on the first platform 11 to perform operations such as loading and detonating explosives at the second zone blast hole 22.
[0042] In a further preferred embodiment, the first layer platform 11 includes a first left platform 111 and a first right platform 112 symmetrically arranged along the center line axis of the platform 1. The first left platform 111 and the first right platform 112 are fixedly connected to the frame structure 10, thereby facilitating the loading and detonation of the first left blasting hole 211 through the first left platform 111, and the loading and detonation of the first right blasting hole 212 through the first right platform 112.
[0043] In an optional embodiment, the top blast hole 23 is located above the top platform 13 and the second-layer platform 12, and the second-zone blast hole 22 is located below the second-layer platform 12. Therefore, workers can stand on the top platform 13 and the second-layer platform 12 to perform operations such as loading and detonating explosives through the top blast hole 23.
[0044] In a further preferred embodiment, the second-layer platform 12 includes a second left-side platform 121 and a second right-side platform 122 symmetrically arranged along the centerline of the platform 1. The second left-side platform 121 and the second right-side platform 122 are fixedly connected to the frame structure 10, thereby facilitating the loading and detonation of explosives at both sides of the top blasting hole 23 through the second left-side platform 121 and the second right-side platform 122.
[0045] In an optional embodiment, the top blasting holes 23 include a first group of holes 231 and a second group of holes 232 arranged concentrically, both of which are arc-shaped. The arc shape of the first group of holes 231 and the second group of holes 232 matches the arc shape of the top of the tunnel face. This enables precise testing of blasting at the tunnel face, improving the blasting effect and the accuracy of the test.
[0046] In optional implementations, such as Figure 6 As shown, the first zone blasting hole 21 and the second zone blasting hole 22 can be cut holes. The schematic diagram of the cross-sectional layout of the angled cut holes is shown below. Figure 6As shown. During detonation, the first zone blast hole 21 can be detonated first. After the free surface is formed, the second zone blast hole 22 can be detonated, and then the central blast hole 20 can be detonated.
[0047] like Figure 4 As shown, each blast hole can be continuously loaded with explosives for detonation. Figure 5 As shown, each blasting hole can be blasted in sections, with the explosives at the hole opening detonated first and the explosives at the bottom of the hole detonated later, thus reducing the resistance line at the bottom of the hole.
[0048] This utility model provides a medium-deep hole blasting test device. By setting up a first-level platform 11, a second-level platform 12, and a top platform 13, operators can stand on the first-level platform 11, the second-level platform 12, and the top platform 13 to operate, thereby facilitating the loading and detonation of explosives in various areas of the blasting holes. By setting up a central blasting hole 20, a first-zone blasting hole 21, a second-zone blasting hole 22, a top blasting hole 23, and an outer contour blasting hole 24, multiple blasting zones at different locations can be formed, facilitating zoned blasting and thus enabling the testing of various blasting schemes. The top blasting hole 23 includes at least two groups of holes arranged in an arc shape, and the outer contour blasting hole 24 is set at the outer contour line of the tunnel face, enabling precise testing of tunnel face blasting and improving the blasting effect and the accuracy of the test.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
