[0002] Hydrogen sulfide is a colorless, highly toxic gas with a strong pungent odor. During the coal mining process, the sulfide in the coal will release hydrogen sulfide due to the friction of coal collapse and squeezing. After hydrogen sulfide enters the human body, it will combine with hemoglobin, hinder the transportation of oxygen in the body, cause poisoning reactions, and even cause coma and death in severe cases. In order to reduce the content of hydrogen sulfide in the coal mining process, coal mining companies have taken a variety of technical measures to reduce the concentration of hydrogen sulfide.
[0003] Existing hydrogen sulfide prevention and control equipment usually achieves the purpose of reducing the concentration of hydrogen sulfide by spraying water. However, this method not only consumes a lot of water resources, but also forms accumulated water that dissolves a large amount of hydrogen sulfide, thus posing a safety hazard and posing a personal threat to workers.

[0032] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] See also Figure 1-7 As shown, an integrated device for preventing and controlling hydrogen sulfide and reducing dust in coal mines of the present invention comprises a device driving mechanism 1, a detection and opening component 6, a hydrogen sulfide prevention and reducing dust component 7 and a ventilation system 5; wherein,
[0034] A drill mechanism 2 and a coal block collecting assembly 3 are rotatably mounted on the left side of the device driving mechanism 1, and the drill mechanism 2 is arranged above the coal block collecting assembly 3. A coal block conveyor belt 4 and a water accumulation absorption assembly 8 are fixedly arranged on the right side of the device driving mechanism 1, and the water accumulation absorption assembly 8 is arranged below the coal block conveyor belt 4.
[0035] The detection opening components 6 are symmetrically arranged in two groups, both of which are fixedly assembled on the upper surface of the drill mechanism 2;
[0036] One side of the hydrogen sulfide prevention and dust reduction component 7 is fixedly mounted on the upper surface of the device driving mechanism 1, and the other side of the hydrogen sulfide prevention and dust reduction component 7 is fixedly mounted on the upper surface of the drill mechanism 2;
[0037] The ventilation system 5 is arranged at the front and rear sides of the device driving mechanism 1 and is fixedly mounted on the side wall of the mining pit.
[0038] In this embodiment, the detection and opening component 6 is used to regularly monitor hydrogen sulfide gas, and through dynamic monitoring and management of the concentration of hydrogen sulfide gas underground, potential safety hazards are discovered and handled in time. The ventilation system 5 increases the air volume of the excavation face to ensure effective dilution and removal of hydrogen sulfide and prevent the accumulation of hydrogen sulfide. When a large amount of hydrogen sulfide gas gushes out of the excavation working face, the air supply should be increased to concentrate the exhaust to ensure that the air volume of the excavation working face is sufficient. The hydrogen sulfide prevention and dust reduction component 7 moistens the coal body that has exploded and reduces the concentration of toxic and harmful gases. At the same time, the hydrogen sulfide prevention and dust reduction component 7 can purify the accumulated water in the mine, reduce the precipitation and diffusion of hydrogen sulfide, reduce the concentration of hydrogen sulfide in the accumulated water, reduce safety risks, and reduce the loss of water resources, saving mining costs. The accumulated water absorption component 8 is used to absorb the accumulated water in the mine and introduce it into the hydrogen sulfide prevention and dust reduction component 7.
[0039] For further information, see Figure 2 As shown, the detection and opening component 6 includes a mechanical arm 61, a first drive motor 62 is fixedly installed at the front end of the mechanical arm 61, a rotating disk 63 is fixedly installed on the output shaft of the first drive motor 62, a hydrogen sulfide detector 64, an ultrasonic surrounding rock crack detector 65 and a fixed rail 66 are fixedly installed on the rotating disk 63, and a sliding driller 67 is slidably installed on the fixed rail 66.
[0040] In this embodiment, when the device mines coal blocks, the hydrogen sulfide detector 64 is driven by the mechanical arm 61 to intermittently detect the hydrogen sulfide concentration in the mine, so as to adjust the mining efficiency, the strength of the ventilation system 5 and the water spraying intensity of the hydrogen sulfide prevention and dust reduction component 7 according to the real-time concentration of hydrogen sulfide, thereby effectively controlling the concentration of hydrogen sulfide, ensuring the effective mining and reducing safety risks; at the same time, the ultrasonic surrounding rock crack detector 65 is driven by the mechanical arm 61 to detect the coal wall to be mined, and the ultrasonic surrounding rock crack detector 65 is driven by the mechanical arm 61 to detect the coal wall to be mined. The stress state and crack degree of the rock mass are evaluated by measuring the propagation speed of ultrasound in the rock mass. Specifically, when there are many cracks in the surrounding rock, the propagation speed of ultrasound will be relatively reduced. By measuring the sound wave propagation time of the surrounding rock within a certain distance in the borehole, the wave speed is calculated, thereby evaluating the integrity and crack conditions of the rock mass, so that the ultrasonic surrounding rock crack detector 65 can make judgments in advance on areas including but not limited to water, faults or cracks, and then advance drilling through the sliding drill 67 to release, extract or seal hydrogen sulfide gas in advance to avoid sudden overflow of hydrogen sulfide.
[0041] Furthermore, the drill bit of the sliding drill 67 is provided with a hollow position, and one end of the absorption tube 68 is connected to the hollow position, and the other end of the absorption tube 68 passes through the sliding drill 67 and is connected to the hydrogen sulfide prevention and control dust reduction component 7.
[0042] In this embodiment, the water, faults or fissures being drilled are absorbed in advance through the absorption pipe 68, so that the water or hydrogen sulfide gas therein is sucked out in advance and introduced into the hydrogen sulfide prevention and dust reduction component 7, thereby further reducing the safety risk and the concentration of hydrogen sulfide gas.
[0043] For further information, see Figure 3 As shown, the hydrogen sulfide prevention and control dust reduction component 7 includes a fixed support frame 71, and three groups of fixed support frames 71 are horizontally arranged, all of which are fixedly assembled on the upper surface of the device driving mechanism 1, and the upper ends of the three groups of fixed support frames 71 are equipped with a water collection tank 72, a water transfer tank 73 and a water purification tank 74 in sequence from left to right, and each group of fixed support frames 71 is fixedly equipped with a water pump 75 on the right side. The three groups of water pumps 75 connect the water collection tank 72, the water transfer tank 73 and the water purification tank 74 to each other, and the output end of the rightmost water pump 75 is connected to the dust reduction adjustment component 79, and the dust reduction adjustment component 79 is fixedly assembled on the upper surface of the drill mechanism 2; a calcium hydroxide solution tank 76 is fixedly assembled on the upper ends of the water transfer tank 73 and the water purification tank 74, and the right side output port of the calcium hydroxide solution tank 76 is embedded in the upper surface of the water purification tank 74.
[0044] In this embodiment, the accumulated water absorption component 8 introduces the absorbed accumulated water into the accumulated water collection tank 72. After the accumulated water in the accumulated water collection tank 72 is precipitated to a certain extent, the accumulated water is introduced into the accumulated water transfer tank 73 through the water pump 75 on the right side of the accumulated water collection tank 72. When the accumulated water in the accumulated water transfer tank 73 reaches a certain capacity, it is introduced into the accumulated water purification tank 74 through the water pump 75 on the right side thereof. At the same time, the calcium hydroxide solution tank 76 will continuously add calcium hydroxide solution into the accumulated water purification tank 74. Calcium hydroxide is a strong alkali, which will react with the hydrogen sulfide gas in the accumulated water to generate calcium sulfide and water. Specifically, in this process, The added calcium hydroxide solution is slightly excessive, so as to ensure the neutralization of hydrogen sulfide to the greatest extent. With the uninterrupted addition of the calcium hydroxide solution tank 76, the loss of calcium hydroxide solution is minimized while ensuring neutralization; the water generated by the above neutralization reaction will be introduced into the dust reduction adjustment component 79 through the right water pump 75 of the water purification tank 74. At the same time, the dust reduction adjustment component 79 is also connected to an external water supply device. The water supply equipment will adjust the water output efficiency in real time according to the solubility in the mine, thereby minimizing the concentration of hydrogen sulfide, ensuring the safety of mining, and reducing water resource consumption to a certain extent, reducing mining costs.
[0045] For further information, see Figure 3 As shown, the lower ends of the accumulated water collection tank 72 and the accumulated water purification tank 74 are bottomless, and a sediment removal assembly 77 is coaxially fixedly assembled thereon.
[0046] Furthermore, a floating object removal assembly 78 is provided on the back side of the accumulated water collection tank 72 .
[0047] In this embodiment, the accumulated water absorbed by the accumulated water absorption component 8 will contain a certain amount of coal dust and small stones and other objects with high density, thereby forming precipitation. At the same time, the hydrogen sulfide in the accumulated water will react with the calcium hydroxide solution to form calcium sulfide. The solubility of calcium sulfide is relatively small, so it may precipitate in the solution in the form of precipitation. The two sets of precipitation removal components 77 will remove the corresponding precipitation, thereby avoiding the patency of the water pipe and preventing blockage; there will also be a certain amount of certain gas bubbles in the accumulated water absorbed by the accumulated water absorption component 8; in some cases, gas bubbles will be generated in the mine water. If the density of these bubbles is small enough, they will float on the water surface, especially specific minerals or rock fragments, because of their internal porous structure and the holes are full of air, so that their overall density is less than water, so they can float on the water surface, move with the water flow, and also cause the patency of the water pipe and cause blockage. In view of this, the floating object removal component 78 is used to effectively remove it, thereby ensuring the components in the accumulated water to the greatest extent and improving the efficiency of accumulated water purification.
[0048] For further information, see Figure 4 As shown, the sediment removal assembly 77 includes a first rotating shaft 771, which is rotatably assembled on the lower end side wall of the water collection tank 72 or the water purification tank 74, one side of the first rotating shaft 771 is fixedly assembled on the output shaft of the second drive motor 773, and a supporting plate 772 is fixedly embedded on the outer side of the middle part of the first rotating shaft 771, and a sediment collection tank 774 is arranged directly below the first rotating shaft 771, and the sediment collection tank 774 is slidably assembled on the inner side of the corresponding fixed support frame 71.
[0049] In this embodiment, after the accumulated water in the accumulated water collection tank 72 is transferred or the neutralization reaction in the accumulated water purification tank 74 is completed, the second drive motor 773 drives the first rotating shaft 771 and the supporting plate 772 to rotate 180°, so that the coal dust and small stones and other high-density sediments or calcium sulfide sediments on them fall into the sediment collection pool 774 below, and then the second drive motor 773 drives the first rotating shaft 771 and the supporting plate 772 to rotate 180° again, return to the initial position to continue the corresponding work, and the staff will regularly collect the sediment in the sediment collection pool 774, and reuse the calcium sulfide of the calcium sulfide sediment as an industrial raw material or fertilizer additive.
[0050] For further information, see Figure 5As shown, the floating object removal assembly 78 includes a fixed connection shell 781, a second rotating shaft 787 is rotatably arranged inside the fixed connection shell 781, one side of the second rotating shaft 787 is fixedly assembled on the output shaft of the third drive motor 782, and a floating object carrying net 783 is fixedly embedded on the outer side of the middle part of the second rotating shaft 787; two groups of first hydraulic cylinders 786 are fixedly assembled on the back side of the fixed connection shell 781, and the other ends of the two groups of first hydraulic cylinders 786 are fixedly assembled with fixed bearing blocks 785, and the fixed bearing blocks 785 are fixedly assembled on the side wall of the floating object collection tank 784, and the floating object collection tank 784 is arranged on the back side of the accumulated water collection tank 72.
[0051] In this embodiment, the accumulated water absorption component 8 introduces the absorbed accumulated water into the accumulated water collection tank 72, and some gas bubbles, specific minerals or rock fragments in the accumulated water will remain on the floating object carrying net 783. When the accumulated water in the accumulated water collection tank 72 needs to be transferred, the two groups of the first hydraulic cylinders 786 will contract, driving the floating object carrying net 783, the fixed connection shell 781 and some gas bubbles or specific minerals or rock fragments thereon to be adjusted to just above the floating object collection tank 784, and the third driving motor 782 drives the second rotating shaft 787 and the floating object carrying net 783 to rotate 180°, so that some gas bubbles or specific minerals or rock fragments thereon fall into the floating object collection tank 784 below, and then the third driving motor 782 drives the second rotating shaft 787 and the floating object carrying net 783 to rotate 180° again and return to the original position, and then the two groups of the first hydraulic cylinders 786 will extend back to the initial position to continue the collection and filtering of some gas bubbles or specific minerals or rock fragments.
[0052] For further information, see Figure 6 As shown, the dust reduction adjustment component 79 includes a fixed frame 791, a clean water tank 792 is fixedly installed on the left side of the fixed frame 791, a boost drive motor 793 is fixedly installed on the upper end of the clean water tank 792, a water pipe 794 is fixedly installed on the lower end of the clean water tank 792, and the other end of the water pipe 794 is connected to a water distribution pipe 797, the water distribution pipe 797 is fixedly installed on the fixed supporting frame 795, and a plurality of groups of atomizing nozzles 796 are fixedly installed on the water distribution pipe 797, and the fixed supporting frame 795 is fixedly installed on the side wall of the clean water tank 792.
[0053] In this embodiment, the clean water tank 792 is also connected to a water supply device. At the same time, the efficiency of the boost drive motor 793 and the number of atomizing nozzles 796 will be adjusted according to the concentration of hydrogen sulfide in the mine, so as to ensure the water output, reduce the concentration of hydrogen sulfide, reduce safety risks, and improve mining efficiency.

[0055] In this embodiment, the self-driving block 81 will adjust the extension length of the sliding sleeve shaft 82 according to the actual width of the mine, ensuring that the accumulated water at each position can be absorbed while protecting the device from damage; at the same time, the self-driving slider 83 will slide periodically, specifically, its sliding frequency is proportional to the mining progress, ensuring the absorption of accumulated water; the accumulated water is scanned by the visual scanning module 86, and absorbed by the accumulated water absorption head 85. At the same time, in order to ensure the absorption of accumulated water at different depths, the absorption of accumulated water is ensured by extending or contracting the second hydraulic cylinder 84.
[0056] The steps of using the integrated device for preventing and controlling hydrogen sulfide and reducing dust in coal mines of the present invention are as follows:
[0057] When the device mines coal blocks, the hydrogen sulfide detector 64 is driven by the mechanical arm 61 to intermittently detect the hydrogen sulfide concentration in the mine, so as to adjust the mining efficiency, the strength of the ventilation system 5 and the water spraying intensity of the hydrogen sulfide prevention and dust reduction component 7 according to the real-time concentration of hydrogen sulfide; at the same time, the mechanical arm 61 drives the ultrasonic surrounding rock crack detector 65 to detect the coal wall to be mined, so that it can judge the water faults, cracks and other areas in advance, and then drill advance holes through the sliding drill 67 to release, extract or seal the hydrogen sulfide gas in advance, and then the drill bit mechanism 2 drills the coal seam to break the coal seam, and the broken coal blocks are gathered by the coal block gathering component 3. Then it is transported out of the coal mine excavation channel through the coal block conveyor belt 4; while the device is running, the water absorption component 8 absorbs the accumulated water in the mine and introduces the accumulated water into the hydrogen sulfide prevention and dust reduction component 7, the hydrogen sulfide prevention and dust reduction component 7 will moisten the coal body that has exploded and fallen, reduce the concentration of toxic and harmful gases, and at the same time the hydrogen sulfide prevention and dust reduction component 7 will purify the accumulated water in the mine, reduce the precipitation and diffusion of hydrogen sulfide, reduce the concentration of hydrogen sulfide in the accumulated water, reduce safety risks, reduce the loss of water resources, and save mining costs.
