[0002] In open-pit coal mines, the pit is typically shaped like a giant inverted cone. Mining primarily involves extracting coal from the bottom and the benches. End-face coal seams, however, refer to coal seams located within the surrounding slopes of an open-pit mine that cannot be directly mined within the conventional open-pit mining boundaries. End-face mining is a special method that involves excavating tunnels along the sidewalls of the open-pit mine to access the coal seams within the end face and then recovering these coal resources using underground mining techniques.

[0003] Currently, most existing open-pit coal mine end-side mining simulation testing devices use manual or semi-automatic methods for vibration testing. This makes it difficult to accurately control the vibration magnitude during the open-pit coal mine end-side mining process. Furthermore, it is difficult for open-pit coal mines to drill as needed during the testing process, and rainfall testing cannot be conducted in real time. This not only results in low simulation testing efficiency but also leads to significant simulation errors. Therefore, it is necessary to design an open-pit coal mine end-side mining simulation testing device based on slope disturbance monitoring and its usage method. Summary of the Invention

[0014] A method for using a simulation test device for end-face coal mining in open-pit coal mines based on slope disturbance monitoring includes the following steps: Step 1: Install the simulated coal mine, move the simulated coal mine and place it inside the second bearing trough, then move the second bearing plate and wed the outer wall of the bottom surface of the second bearing plate with the inner side wall of the first bearing trough. Next, rotate the external connector along the first and second connecting holes to make a detachable connection between the first bearing plate and the second bearing plate, thereby limiting the simulated coal mine to the upper surface of the first bearing plate. Step two: Drilling is performed on the simulated coal mine at the simulated mining location. The second servo motor drives the second lead screw to rotate, which, under the action of the second ball nut and the second limit hole sliding along the second limit rod, drives the second slider to move linearly horizontally to the desired position. Then, the third servo motor drives the third lead screw to rotate, which, under the action of the third ball nut and the through hole sliding along the inner wall of the side groove, drives the third slider to move linearly vertically to the desired position. Subsequently, the second drive motor drives the second rotating shaft to rotate, which drives the second rotating plate to rotate in a circle, thereby driving the drill rod to rotate to the desired angle. Then, the third electric hydraulic cylinder drives the third hydraulic telescopic rod to extend and slide, which drives the drill rod to move linearly towards the outer wall of the simulated coal mine. At the same time, the sliding action of the inner wall of the third limit hole along the third limit rod ensures the stability of the linear movement of the drill rod. Finally, the drilling rig drives the drill rod to rotate, thereby excavating a simulated roadway on the outer wall of the simulated coal mine as needed. Step 3: Conduct simulated rainfall test on the simulated coal mine. The first servo motor drives the first lead screw to rotate, which in turn drives the first slider to move horizontally under the action of the inner wall of the first ball nut and the first limit hole sliding along the outer wall of the first limit rod. This drives the sprayer to move horizontally to the required position, and then the spray liquid can be sprayed along the spray hole to the outer surface of the simulated coal mine through the water inlet pipe to conduct simulated rainfall test. Step four: Conduct earthquake tests on the simulated coal mine. The first electric hydraulic cylinder drives the first hydraulic telescopic rod to extend and slide, thereby causing the first bearing plate to simulate earthquake vibration in the vertical direction under the action of the first electric hydraulic cylinder rotating along the first connecting shaft and the first roof plate rotating along the second connecting shaft. Then, the second electric hydraulic cylinder drives the second hydraulic telescopic rod to extend and slide, thereby causing the first bearing plate to simulate earthquake vibration in the horizontal direction under the action of the second electric hydraulic cylinder rotating along the third connecting shaft and the second roof plate rotating along the fourth connecting shaft. Step 5: Real-time image monitoring of the simulated coal mine is performed. The first drive motor drives the first rotating shaft to rotate, which in turn drives the first rotating plate to rotate in a circle. This, in turn, drives the spherical camera to rotate in a circle to the required position, so that the spherical camera can record the changes in the shape of the simulated coal mine in real time.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. First, move the simulated coal mine and place it inside the second bearing trough. Then, move the second bearing plate and wed the outer wall of the bottom surface of the second bearing plate with the inner wall of the first bearing trough. Next, rotate the external connector along the first and second connecting holes to detachably connect the first and second bearing plates, thereby limiting the simulated coal mine to the upper surface of the first bearing plate. Then, drive the second lead screw to rotate through the second servo motor. Under the action of the second ball nut and the second limiting hole sliding along the second limiting rod, the second slider can be moved horizontally linearly to the desired position. Then, drive the third lead screw to rotate through the third servo motor. Under the action of the third ball nut and the through hole sliding along the inner wall of the side groove, the third slider can be moved vertically linearly to the desired position. The device is set up, and then the second drive motor drives the second rotating shaft to rotate, which in turn drives the second rotating plate to rotate in a circle, thereby driving the drill rod to rotate to the required angle. Then, the third electric hydraulic cylinder drives the third hydraulic telescopic rod to extend and slide, which drives the drill rod to move linearly towards the outer wall of the simulated coal mine. At the same time, the stability of the linear movement of the drill rod is ensured by the sliding action of the third limit hole along the third limit rod. Finally, the drilling rig drives the drill rod to rotate, thereby excavating a simulated roadway on the outer wall of the simulated coal mine as needed. This effectively realizes that the open-pit coal mine end-side mining simulation test device has the function of automatically drilling simulated roadways in the simulated coal mine as needed. Moreover, the assembly and disassembly of the simulated coal mine is relatively convenient, which not only improves the simulation test efficiency of the device, but also ensures the simulation test accuracy of the device.

[0016] 2. This invention drives the first lead screw to rotate via the operation of the first servo motor. Under the action of the sliding action of the first ball nut and the inner side wall of the first limiting hole along the outer side wall of the first limiting rod, the first slider can be moved horizontally. This, in turn, can move the sprayer horizontally to the desired position. Then, through the water inlet pipe, the spray liquid can be sprayed along the spray hole onto the outer surface of the simulated coal mine to conduct simulated rainfall tests. This effectively realizes that the open-pit coal mine end-side mining simulation test device has the function of simulating rainfall tests on simulated mines according to various rainfall intensities. Moreover, the rainfall position and rainfall intensity can be adjusted as needed, improving the diversity of simulation test patterns of the device.

[0017] 3. This invention uses a first electric hydraulic cylinder to drive a first hydraulic telescopic rod to extend and slide, thereby causing the first bearing plate to simulate seismic vibrations in the vertical direction under the action of the first electric hydraulic cylinder rotating along the first connecting shaft and the first top plate rotating along the second connecting shaft. Then, the second electric hydraulic cylinder drives a second hydraulic telescopic rod to extend and slide, thereby causing the first bearing plate to simulate seismic vibrations in the horizontal direction under the action of the second electric hydraulic cylinder rotating along the third connecting shaft and the second top plate rotating along the fourth connecting shaft. Next, the first drive motor drives the first rotating shaft to rotate, thereby causing the first rotating plate to rotate in a circle, which in turn causes the spherical camera to rotate in a circle to the desired position. In this way, the spherical camera can record the morphological changes of the simulated coal mine in real time, effectively realizing the function of automatically simulating the impact of earthquakes on open-pit coal mines in this open-pit coal mine end-face mining simulation test device. The simulation process is relatively stable, and multi-angle monitoring and test image acquisition can be carried out throughout the simulation test, ensuring the reliability of the simulation test results.

[0030] A method for using a simulation test device for end-face coal mining in open-pit coal mines based on slope disturbance monitoring includes the following steps: Step 1: Install the simulated coal mine, move the simulated coal mine and place it inside the second bearing trough 305, then move the second bearing plate 304 and wed the outer wall of the bottom surface of the second bearing plate 304 with the inner wall of the first bearing trough 302.

Thus, the present invention has the function of conducting simulated rainfall tests on simulated mines according to various rainfall intensities. Step four: Conduct earthquake tests on the simulated coal mine.
