[0002] Coal mine subsidence areas are hazardous areas left behind after coal mining. They not only damage the original topography but also cause a series of ecological problems such as land subsidence, surface cracks, and soil erosion. These problems not only affect the local ecological balance but also threaten the lives and production of surrounding residents. Currently, ecological restoration methods for coal mine subsidence areas mainly include land reclamation, vegetation restoration, and grouting. However, existing restoration methods, such as traditional grouting, lack systematic improvement of soil structure, leading to recurring surface subsidence. Therefore, improvements are needed.

[0050] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of an ecological restoration device for coal mine subsidence areas.

[0051] An ecological restoration device for coal mine subsidence areas includes multiple support legs 1 and casters 2. It also includes a grouting mechanism mounted on the support legs 1 for grouting operations and a soil improvement mechanism mounted on the grouting mechanism for soil improvement. The soil improvement mechanism includes two support frames 3 mounted on the grouting mechanism for component installation; a mixing cylinder 4 mounted on and fixedly connected to the support frames 3; a fixing cylinder 5 located inside and fixedly connected to the mixing cylinder 4; a drive motor 6 located inside and fixedly connected to the fixing cylinder 5; a mixing shaft 7 located at the output end of the drive motor 6 and fixedly connected to the output end of the drive motor 6; a mixing component 8 mounted on and fixedly connected to the mixing shaft 7; a metering detector 9 mounted on and fixedly connected to the mixing cylinder 4; and a feed pipe 13 mounted on and fixedly connected to the mixing cylinder 4.

[0052] refer to Figure 1 and Figure 4 In a preferred embodiment, the soil improvement mechanism further includes: a fixing frame 11, which is disposed on the feed pipe 13 to fix the feed pipe 13; and a feeding part, which is disposed on the mixing cylinder 4 for feeding materials.

[0053] refer to Figure 2 and Figure 5 In a preferred embodiment, the feeding unit includes: a partition plate 12 disposed on the mixing cylinder 4 and fixedly connected to the mixing cylinder 4; two feeding channels 20 disposed on the mixing cylinder 4 and fixedly connected to the mixing cylinder 4; and two control valves 10 disposed inside the mixing cylinder 4 and fixedly connected to the mixing cylinder 4.

[0054] refer to Figure 2 In a preferred embodiment, the grouting mechanism includes: a grouting part disposed on the support leg 1 for grouting work; and a connecting part disposed on the grouting part for connecting with the soil improvement mechanism.

[0055] refer to Figure 1 and Figure 3 In a preferred embodiment, the grouting unit includes: a mounting plate 14, which is disposed on the support leg 1 and fixedly connected to the support leg 1; a grouting box 15, which is disposed on the mounting plate 14 and fixedly connected to the mounting plate 14; and a grouting pump 16, which is disposed on the mounting plate 14 and fixedly connected to the mounting plate 14.

[0056] refer to Figure 1In a preferred embodiment, the connection includes: a grouting pipe 17, which is disposed on the grouting pump 16 and fixedly connected to the grouting pump 16; a layered grouting head 18, which is disposed on the grouting pipe 17 and connected to the grouting pipe 17; and a pipe fitting 19, which is disposed on the mounting plate 14 and used to fix the grouting pipe 17.

[0057] With this setup, the mixing cylinder 4 is used to add organic fertilizer and microbial amendment, allowing both to be injected together to improve the soil. During grouting, the metering detector 9 can open the channel to allow the mixture of organic fertilizer and microbial amendment to enter the grouting pipe 17 through the feed pipe 13. At the same time, the metering detector 9 will not be continuously open, but will add a fixed amount of organic fertilizer and microbial amendment to the grouting pipe 17 at regular intervals. The grouting pipe 17 and the feed pipe 13 can be connected, and the feed pipe 13 is provided with a one-way channel at the connection position to prevent the grouting liquid from entering the feed pipe 13. The layered grouting head 18 is equipped with a pressure sensor, which can perform layered grouting according to the subsidence depth to ensure that deep cavities are filled evenly and reduce secondary surface subsidence.

[0058] This device, equipped with a grouting mechanism, can perform grouting work in subsidence areas to consolidate the soil and prevent recurrence of subsidence. The grouting mechanism uses layered grouting heads 18 to inject grout in layers according to the subsidence depth, ensuring uniform filling of deep cavities and reducing secondary surface subsidence. Furthermore, the device incorporates a soil improvement mechanism that allows for the addition of uniformly mixed organic fertilizer and microbial conditioners to the grouting solution during the grouting process, thereby improving the soil.

[0059] Working principle: When the device is in operation, it is moved to the location where grouting is required. Then, the grouting liquid in the grouting tank 15 is injected into the subsidence area through the grouting pipe 17 and the layered grouting head 18 by the grouting pump 16. At the same time as the grouting is in progress, the control valve 10 is opened to allow the organic fertilizer and microbial conditioner inside to enter the mixing zone. The drive motor 6 drives the mixing shaft 7 to rotate, and the mixing shaft 7 drives the mixing component 8 to rotate, thereby mixing the organic fertilizer and microbial conditioner. Then, the metering detector 9 opens the channel to allow the mixture of organic fertilizer and microbial conditioner to enter the feed pipe 13 and be injected into the grouting pipe 17 along with the grouting liquid, thereby improving the soil.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
