[0032] Working principle: Before using the device, first drill the required deep hole inside the mine, then transport the operating platform to the vicinity of the deep hole, then connect a specified number of monitoring unit devices 4 in series according to the depth of the deep hole, insert the monitoring unit devices 4 in series into the deep hole and connect the injection docking hose 26. After insertion, since the limit clamping device 3 can clamp the inner wall of the deep hole, the monitoring unit device 4 will not fall out or slide regardless of the inclination angle of the deep hole, ensuring the accurate installation position. Then, connect a specified number of plugging unit devices 2 in series according to the length of the deep hole to be plugged, insert the plugging unit devices 2 in series near the opening of the deep hole, and insert the injection docking hose 26 into the monitoring tube 205 and seal it with the sealing sleeve 22. Then, the slurry delivery pipe 202 is connected to the grouting distribution box 8 through the grouting docking hose 25, the liquid injection docking hose 26 is connected to the liquid injection branch pipe 18, and the water injection pipe 204 is connected to the water injection branch pipe 16 through the water injection docking hose 27. Then, the grouting pump 11 is used to inject grout into the plugging soft bag 201 of each plugging unit device 2 so that the plugging soft bag 201 can seal the opening position of the deep hole. The injected slurry can also play a role in the mine after solidification. The deep hole is supported by the liquid injection pump 12, and then the pressure-bearing soft bag 403 is injected with liquid, so that the pressure-bearing soft bag 403 can fit and support the inner wall of the deep hole. Subsequently, the water is injected into the water injection pipe 204 through the water injection pump 14. The water will pass through the water injection pipe 204 into the deep hole, and then be guided to the deep hole through the water guide pipe 404 and flow out from the water injection hole on the water guide pipe 404 to completely fill the deep hole. The injected water flow can relieve the impact ground pressure. When the pressure is released by injecting water, the manual valves on the water injection branch pipe 16 and the liquid injection branch pipe 18 can be closed, and the monitoring link can be entered at this time. During the monitoring process, when the pressure gauge 23 on the water injection docking hose 27 shows that the internal pressure of the deep hole is reduced, water injection and pressure relief can continue. When the pressure gauges 23 on the deep hole water injection docking hose 27 and the liquid injection docking hose 26 both show that the internal pressure of the deep hole is increased, it indicates that a collapse has occurred inside the deep hole. The scale of the collapse can be preliminarily evaluated based on the size of the pressure increase, and the evaluation process can also be handed over to the controller 17 for automatic processing. Since the device can directly inject water into the deep hole to reduce pressure, and can seal and support the opening of the deep hole through the sealing unit device 2, it can effectively improve the safety of the mine. At the same time, it can also monitor the collapse state inside the deep hole in real time through the monitoring unit device 4 in conjunction with the pressure gauge, and each operating platform 1 can monitor multiple adjacent deep holes through the grouting distribution box 8, the water injection distribution box 15, and the liquid injection distribution box 13, so as to evaluate the risk status of each deep hole according to the collapse data inside the deep hole, facilitate the implementation of corresponding safety measures, thereby improving the safety of mine mining, and therefore has a high practical value.
