[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 4 As shown, the explosive installation device 100 for mine blasting in an embodiment of the present invention includes a mounting seat 10, and the mounting seat 10 includes a plurality of arc-shaped pieces 1. The plurality of arc-shaped pieces 1 form a mounting cavity 101 for installing an explosive roll, and the arc-shaped pieces 1 have a accommodating cavity for accommodating a carbon monoxide catalyst, and the cavity wall of the accommodating cavity includes a base area and a weak area 1121, and the thickness of the weak area 1121 is less than the thickness of the base area.

[0035] The explosive installation device 100 for mine blasting according to the embodiment of the present invention comprises a plurality of arc-shaped sheets 1 filled with carbon monoxide catalyst wrapped around an explosive roll, and the explosive roll is placed in a blasting hole. After the explosive explodes, a high-pressure shock wave is generated which diffuses in all directions, so that the cavity wall of the accommodating cavity is first ruptured from the weak area 1121, and the carbon monoxide catalyst is ejected from the weak area 1121. The entire blasting hole is filled with the carbon monoxide catalyst, and the carbon monoxide generated after the explosion of the explosive is largely eliminated. At the same time, the carbon monoxide catalyst is sprayed into the cracks of the coal body and chemically reacts with the carbon monoxide in the coal seam voids, thereby reducing the carbon monoxide in the coal seam cracks.

[0036] The explosives installation device 100 for mine blasting in the embodiment of the present invention can react quickly with carbon monoxide after the explosion of the explosives, quickly reduce the carbon monoxide content in the mine, reduce the risk of excessive carbon monoxide in the mine, and improve the safety of deep hole blasting in the mine. It has a high efficiency in treating carbon monoxide and does not need to suspend production, thereby ensuring production efficiency.

[0037] Optionally, the carbon monoxide catalyst is hopcalite.

[0038] Hopcalite has the characteristics of high activity, high stability and wide applicability. It can catalytically oxidize harmful gases such as carbon monoxide under normal pressure, thereby significantly eliminating carbon monoxide in mines.

[0039] Optionally, the explosive roll is cylindrical, and the shape of the installation cavity 101 matches the shape of the explosive roll, so that the axial direction of the installation cavity 101 is consistent with the axial direction of the explosive roll, the circumferential direction of the installation cavity 101 is consistent with the circumferential direction of the explosive roll, and the radial direction of the installation cavity 101 is consistent with the radial direction of the explosive roll.

[0040] As an example, Figure 1 As shown, the arc-shaped sheet 1 is used to enclose the side wall of the installation cavity 101, which is an arc-shaped wall, and the arc-shaped wall forms part of the cavity wall of the installation cavity 101. The multiple arc-shaped sheets 1 are closely attached to the explosive roll, so that the carbon monoxide catalyst is wrapped outside the explosive roll, so that after the explosive explodes, the carbon monoxide catalyst can rush into the blasting hole and the coal seam fissure with the high-pressure shock wave, thereby achieving a significant elimination of carbon monoxide.

[0041] In some embodiments, Figure 2 and Figure 4 As shown, the accommodating chamber includes a plurality of mutually connected separation chambers 11 , a portion of the chamber wall of the separation chamber 11 forms a basic area, and another portion forms a weak area 1121 .

[0042] Through the above arrangement, a plurality of weak areas 1121 are formed on each arc-shaped sheet 1. After the explosives explode, a plurality of nozzles are formed on the cavity wall of the accommodating cavity. The carbon monoxide catalyst is ejected more evenly through the plurality of nozzles, so that the carbon monoxide catalyst is evenly distributed in the blasting hole and the cracks of the coal body, thereby fully contacting with the carbon monoxide and reacting chemically, thereby further improving the efficiency of eliminating carbon monoxide.

[0043] In some embodiments, Figure 2 and Figure 3 As shown, the cavity wall of the separation cavity 11 includes a first cavity wall 111 and a second cavity wall 112, the second cavity wall 112 is arranged on a side of the first cavity wall 111 away from the installation cavity 101, and a portion of the second cavity wall 112 forms a weak area 1121; the circumferential dimension of the separation cavity 11 along the installation cavity 101 gradually decreases from the first cavity wall 111 to the weak area 1121; and / or the axial dimension of the separation cavity 11 along the installation cavity 101 gradually decreases from the first cavity wall 111 to the weak area 1121.

[0044] After the explosion of the explosives, a high-pressure shock wave is generated radially outward along the installation cavity 101. Through the above arrangement, the separation cavity 11 gradually shrinks outward from the installation cavity 101 to the weak area 1121. The separation cavity 11 is equivalent to an energy-gathering hole. After the high-pressure shock wave passes through the separation cavity 11, a high-pressure jet is formed to flush the carbon monoxide catalyst from the weak area 1121 into the deep cracks of the coal body, thereby improving the penetration ability of the carbon monoxide catalyst, so that the carbon monoxide catalyst can react with the carbon monoxide deep in the cracks, thereby reducing the carbon monoxide content and improving the safety of deep hole blasting in mines.

[0045] As an example, Figure 3 and Figure 4 As shown, the accommodating chamber includes four separation chambers 11, and the four separation chambers 11 are distributed in two rows and two columns, wherein two separation chambers 11 arranged along the circumference of the installation chamber 101 form a row, and two separation chambers 11 arranged along the axial direction of the installation chamber 101 form a column. The separation chamber 11 is divided into a first part 113 and a second part 114 along the radial direction of the installation chamber 101, the first part 113 is arc-shaped and coaxial with the arc-shaped wall of the arc-shaped sheet 1, and the first parts 113 of the four separation chambers 11 are interconnected; the second part 114 is in the shape of a quadrangular pyramid, and the top of the quadrangular pyramid of the second part 114 forms the above-mentioned weak area 1121.

[0046] The cavity wall of the first part 113 close to the installation cavity 101 is the first cavity wall 111, and the four cavity walls of the second part 114 are the second cavity wall 112. After the explosive explodes, the high-pressure shock wave breaks through the first cavity wall 111 and then rushes into the separation cavity 11, and then breaks through the weak area 1121 under the energy gathering and guiding effect of the separation cavity 11, and rushes the carbon monoxide catalyst into the deep cracks of the coal body, thereby greatly reducing the carbon monoxide inside the coal body and improving the safety of deep hole blasting in mines.

[0047] like Figure 1 As shown, each arc-shaped sheet 1 is provided with a filling hole 115, and the filling hole 115 is arranged on the cavity wall of the separation cavity 11, and a blocking nut is connected to the filling hole 115, and the blocking nut is threadedly matched with the filling hole 115; the blocking nut is removed, and the carbon monoxide catalyst can be filled into the accommodating cavity through the filling hole 115, and the blocking nut is sealed in the filling hole 115 to achieve the sealing of the accommodating cavity.

[0048] In some embodiments, at least one arc-shaped piece 1 is a first arc-shaped piece 12 , and at least one arc-shaped piece 1 is a second arc-shaped piece 13 . The second arc-shaped piece 13 is slidably connected to the first arc-shaped piece 12 along the circumference of the installation cavity 101 .

[0049] By sliding the first arc-shaped piece 12 relative to the second arc-shaped piece 13, the cross-sectional size of the installation cavity 101 can be adjusted to accommodate explosive rolls of different diameters, thereby improving the flexibility of the installation device and expanding its application range.

[0050] In addition, by sliding the second arc-shaped piece 13 and the first arc-shaped piece 12 relatively close to each other, the first arc-shaped piece 12 and the second arc-shaped piece 13 can be overlapped with each other, reducing the occupied volume of the first arc-shaped piece 12 and the second arc-shaped piece 13, which is more conducive to the transportation of the explosive installation device 100.

[0051] As an example, Figure 1 As shown, a first arc-shaped piece 12 and a second arc-shaped piece 13 form a group of arc-shaped structures. The number of the arc-shaped structures is three, and the three arc-shaped structures surround the installation cavity 101 .

[0052] In some embodiments, Figure 2 and Figure 3 As shown, the first arc-shaped piece 12 includes an inner plate 121 and an outer plate 122 connected to each other, the inner plate 121 has a slide groove 1211, and the second arc-shaped piece 13 is slidably disposed in the slide groove 1211 along the circumference of the installation cavity 101.

[0053] The second arc-shaped piece 13 slides in the slide groove 1211. When the arc-shaped piece 1 is wrapped around the outside of the explosive roll, the first arc-shaped piece 12 is first fitted to the explosive roll, and then the second arc-shaped piece 13 is pulled out of the slide groove 1211, and the second arc-shaped piece 13 is made to fit the explosive roll, thereby wrapping the explosive roll; the slide groove 1211 can limit the sliding trajectory of the second arc-shaped piece 13 and improve the smoothness of the sliding of the second arc-shaped piece 13.

[0054] As an example, Figure 1 As shown, the inner plate 121 of the first arc-shaped piece 12 and the second arc-shaped piece 13 enclose the above-mentioned installation cavity 101, and the outer plate 122 of the first arc-shaped piece 12 has the above-mentioned accommodation cavity inside.

[0055] The thickness of the groove wall of the slide groove 1211 close to the installation cavity 101 is relatively small. Therefore, when the second arc-shaped piece 13 slides out of the slide groove 1211, the distance between the second arc-shaped piece 13 and the explosive roll is relatively small. Applying force to the second arc-shaped piece 13 can make the second arc-shaped piece 13 fit.

[0056] It can be understood that the second arc-shaped piece 13 is slidably connected to the first arc-shaped piece 12, and the first arc-shaped piece 12 is completely in contact with the explosive roll. Even if the second arc-shaped piece 13 is only partially in contact with the explosive roll, the explosive roll can still be wrapped.

[0057] Optionally, a sliding structure is provided between the first arc-shaped piece 12 and the inner plate 121 , so that the relative sliding of the first arc-shaped piece 12 and the second arc-shaped piece 13 is smoother.

[0058] In other embodiments, a positioning structure may be further provided between the first arc-shaped piece 12 and the inner plate 121 so as to fix the relative positions of the first arc-shaped piece 12 and the second arc-shaped piece 13 after the relative positions thereof are adjusted.

[0059] In some embodiments, Figure 4 and Figure 5 As shown, the explosive installation device 100 for mine blasting also includes an anti-slip claw 2, which has a connecting end and a stop end for stopping against the wall of the blasting hole, the connecting end is connected to the side wall of the mounting seat 10 away from the mounting cavity 101, and the anti-slip claw 2 extends obliquely along the axial direction of the mounting cavity 101 in a direction away from the mounting cavity 101.

[0060] It is known that the drilling depth and inclination angle of deep hole blasting in the roof are both large, and during the explosive filling process, the explosives often slip out along the blasting hole. At present, the operator needs to fill in 10cm long gun mud for every few explosive rolls to increase resistance and prevent the explosive rolls from slipping out; this method reduces the effective utilization rate of the blasting hole, and requires deeper drilling to meet the blasting needs, which increases the amount of construction drilling and has high labor costs.

[0061] By providing the anti-skid claws 2, after the explosive roll is loaded into the blasting hole through the explosive installation device 100, the anti-skid claws 2 are in the blasting hole in the form of barbs and stop against the hole wall, thereby achieving a better anti-skid effect and preventing the explosive roll from slipping out of the blasting hole.

[0062] In addition, the anti-slip claws 2 are installed on the outside of the mounting seat 10, which will not occupy the effective depth of the blasting hole, thereby improving the effective utilization rate of the blasting hole, reducing the amount of construction drilling, and reducing labor costs.

[0063] Alternatively, if Figure 5 As shown, the extension direction of the anti-slip claw 2 forms an angle α with the axial direction of the mounting cavity 101 (i.e. the axial direction of the explosive roll), and the range of α is 15° to 45°, such as 20°, 25°, 30°, 35°, 40°.

[0064] Thereby, a better anti-slip effect can be achieved.

[0065] Optionally, the anti-slip claw 2 is made of steel.

[0066] As an example, Figure 5 and Figure 6 As shown, there are three anti-slip claws 2, which correspond to the three first arc-shaped pieces 12 respectively, and the anti-slip claws 2 are connected to the side wall of the first arc-shaped piece 12 away from the installation cavity 101; the explosive installation device 100 is wrapped around the outside of the explosive roll, and the three anti-slip claws 2 are barbed and stop at the wall of the blasting hole at the same time, which can achieve a better anti-slip effect.

[0067] In some embodiments, Figure 7 As shown, the anti-slip claw 2 is rotatably connected to the arc-shaped piece 1, and an elastic member 21 is provided between the anti-slip claw 2 and the arc-shaped piece 1. The elastic member 21 is used to apply elastic force to the anti-slip claw 2 so that the anti-slip claw 2 tends to rotate in the direction of stopping the blasting hole wall.

[0068] Through the above arrangement, in the process of loading the explosive roll into the blasting hole, the anti-slip claw 2 can be rotated into the blasting hole so as to load the explosive roll into the blasting hole. After the explosive roll is loaded into place, the anti-slip claw 2 can automatically rotate outward under the action of the elastic member 21 and stop against the wall of the blasting hole, thereby preventing the explosive roll from sliding out of the blasting hole.

[0069] Alternatively, if Figure 7 As shown, the elastic member 21 is a spring, and two ends of the spring are respectively connected to the anti-slip claw 2 and the first arc-shaped piece 12.

[0070] In some embodiments, Figure 8 As shown, the explosive installation device 100 for mine blasting also includes a clamping assembly 3, which includes a first clamping portion 31 and a second clamping portion 32, and the first clamping portion 31 and the second clamping portion 32 are clamped together; there are multiple mounting seats 10, and the multiple mounting seats 10 are arranged in sequence along the axial direction of the mounting cavity 101, and two adjacent mounting seats 10 are respectively connected to the first clamping portion 31 and the second clamping portion 32.

[0071] Through the above arrangement, a suitable number of mounting seats 10 can be selected according to the length of the explosive roll, and multiple mounting seats 10 can be connected in sequence so that the total length of the explosive installation device 100 matches the length of the explosive roll, thereby enabling the carbon monoxide catalyst to completely wrap the explosive roll, thereby achieving a better elimination effect on carbon monoxide in the mine.

[0072] As an example, Figure 1 and Figure 8 As shown, three snap-in assemblies 3 are provided between two adjacent mounting seats 10. The three snap-in assemblies 3 correspond to three first arc-shaped pieces 12 respectively. The first arc-shaped pieces 12 of two adjacent mounting seats 10 correspond to each other and are connected through the snap-in assemblies 3, thereby realizing a stable connection between two adjacent mounting seats 10.

[0073] The two first arc-shaped pieces 12 corresponding to two adjacent mounting seats 10 are named arc-shaped piece 1 and arc-shaped piece 2 respectively. The arc-shaped piece 1 and arc-shaped piece 2 are taken as examples to further describe the clamping assembly 3 hereinafter.

[0074] The first clamping portion 31 is arranged on the end surface of the arc-shaped member 1, and the first clamping portion 31 is L-shaped. A clamping groove is formed between the first clamping portion 31 and the end surface of the first arc-shaped piece 12. The two first clamping portions 31 are symmetrically arranged on both sides of the arc-shaped member 1 along the circumference of the installation cavity 101. The second clamping portion 32 includes a fixed block 321 and two clamping blocks 322. The fixed block 321 is arranged at the middle position of the two end surfaces of the arc-shaped member. The two clamping blocks 322 extend from the fixed block 321 to both sides. The two clamping blocks 322 are respectively clamped and matched with the two clamping grooves, thereby realizing the connection between the first clamping portion 31 and the second clamping portion 32.

[0075] There are three mounting seats 10, and the total length of the three mounting seats 10 after being connected in sequence matches the length of the explosive roll, which are the first mounting seat 102, the second mounting seat 103 and the third mounting seat 104. The first mounting seat 102 is arranged near the opening of the blasting hole, and the third mounting seat 104 is arranged near the bottom of the blasting hole. The end surface of the first mounting seat 102 facing the second mounting seat 103 is provided with a first clamping portion 31, and both ends of the second mounting seat 103 are provided with a second clamping portion 32, and both ends of the third mounting seat 104 have a first clamping portion 31, so that the first mounting seat 102, the second mounting seat 103 and the third mounting seat 104 can be connected in sequence.

[0076] In order to ensure that the explosive roll is in full contact with the bottom of the blasting hole, loess may be filled at the end of the third mounting seat 104 away from the second mounting seat 103 .

[0077] Among them, only one end of the first mounting seat 102 close to the blasting hole opening is provided with three anti-slip claws 2, so that the number of anti-slip claws 2 can be reduced and the production cost can be reduced.

[0078] It is understandable that the first mounting seat 102, the second mounting seat 103 and the third mounting seat 104 can be mass-produced. In actual applications, according to the length of the explosive roll, a corresponding number of first mounting seats 102, second mounting seats 103 and third mounting seats 104 can be selected to make the total length of the explosive installation device 100 match the length of the explosive roll.

[0079] According to the length of the blasting hole, a plurality of explosive rolls can be filled into the blasting hole. The operator can first assemble the explosive installation device 100 with the explosive rolls, and then put the plurality of explosive rolls into the blasting hole in sequence.

[0080] In some embodiments, Figure 8 As shown, the explosive installation device 100 for mine blasting further comprises a tightening belt 4, which is wound around a plurality of arc-shaped sheets 1, and is used to apply a force to the arc-shaped sheets 1 so that the arc-shaped sheets 1 fit the explosive roll.

[0081] Through the above arrangement, the fastening belt 4 is wound around the plurality of arc-shaped sheets 1. By tightening the fastening belt 4, the arc-shaped sheets 1 can be closely fitted to the explosive roll, thereby achieving assembly of the explosive installation device 100 and the explosive roll.

[0082] Optionally, the fastening strap 4 is a self-locking nylon cable tie.

[0083] Therefore, the fastening belt 4 is easy to use, low in cost, and has a self-locking function. After being tightened, the fastening belt 4 can make the multiple arc-shaped pieces 1 fit tightly with the explosive roll, thereby achieving the wrapping of the explosive roll by the explosive installation device 100.

[0084] As an example, Figure 1 As shown, a fastening ring 41 is fixedly provided at the middle position of the side wall of the first arc-shaped piece 12 away from the installation cavity 101, and the three first arc-shaped pieces 12 are wrapped around the outside of the explosive roll. After the fastening belt 4 passes through the three fastening rings 41 in sequence, the two ends of the fastening ring 41 are tightened together, so that the first arc-shaped piece 12 and the second arc-shaped piece 13 can tightly wrap the explosive roll, thereby realizing the assembly of the explosive installation device 100 and the explosive roll, and the operation is relatively simple.

[0085] In some embodiments, the surface of the fastening tape 4 has an antistatic coating.

[0086] By providing the fastening belt 4 with an antistatic coating, static electricity can be prevented from being generated during the process of loading explosives, thereby preventing the explosives from being ignited prematurely, thereby improving the safety of deep hole blasting in mines.
