Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0029] Figure 1 This is a schematic diagram of the structure of the isotope fluid tracing underground rock mass geological early warning device according to an embodiment of this application.

[0030] Figure 2 This is a structural block diagram of an early warning system according to an embodiment of this application.

Detailed Implementation Methods

[0031] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] like Figure 1 As shown in the figure, this application embodiment proposes an isotope fluid tracing underground rock mass geological early warning device, including a protective cylinder 1;

[0033] Storage tank 2 is located inside the protective cylinder 1 and contains isotope tracer material fluid. Specifically, storage tank 2 is a gas tank that can be pressurized to output isotope tracer material fluid. The output end of storage tank 2 is equipped with a pressure checking component 21 for detecting the gas pressure inside storage tank 2. The pressure checking component 21 is a pressure pointer.

[0034] An extendable rubber tube 10 is disposed inside the protective cylinder 1, with one end connected to the storage tank 2 and the other end protruding from the lower end of the protective cylinder 1. Specifically, a control switch 12 is provided at one end of the extendable rubber tube 10 near the storage tank 2, and the control switch 12 is electrically connected to the control mechanism 6.

[0035] The detection mechanism 3 is located inside the bottom of the protective cylinder 1 and is used to detect the diffusion of the isotope tracer material fluid in the rock mass. Specifically, the detection mechanism 3 is an isotope probe located inside the bottom of the protective cylinder 1.

[0036] The ranging mechanism 4 is located inside the bottom of the protective cylinder 1 and is used to detect the distance between the protective cylinder 1 and the isotope tracer material fluid. Specifically, the ranging mechanism 4 is a ranging sensor located inside the bottom of the protective cylinder 1. At the same time, the ranging sensor is used to detect the distance to the rock surface to prevent the isotope probe from being hit and causing its sensitivity to deteriorate.

[0037] The data acquisition module 5 is located inside the protective cylinder 1 and is electrically connected to the detection mechanism 3 and the ranging mechanism 4 respectively, and is used to acquire the information detected by the detection mechanism 3 and the ranging mechanism 4;

[0038] The control mechanism 6 is located inside the protective cylinder 1 and is electrically connected to the detection mechanism 3, the ranging mechanism 4 and the data acquisition module 5 respectively.

[0039] Furthermore, the isotope fluid tracing underground rock mass geological early warning device also includes a central control module 7 for sending instructions to the control mechanism 6 and receiving information collected by the data acquisition module 5. Specifically, the central control module 7 includes a processing module 71 for receiving and processing the information collected by the data acquisition module 5, a display module 72 for displaying the collected information, and a host 73 for receiving the information processed by the processing module 71. The central control module 7 remotely controls the control mechanism 6, using segmented pressurization of isotope fluid to trace geological conditions such as pores, fractures, faults, and groundwater in the underground rock mass. Through two pressurization cycles, the detection mechanism 3 understands the diffusion of isotope fluid in the rock mass, thereby clarifying the basic development status of the underground rock mass.

[0040] Furthermore, the bottom end of the protective cylinder 1 is also provided with an airtight baffle 11 for preventing the isotope tracer material fluid from diffusing into the protective cylinder 1. Specifically, the airtight baffle 11 is a foldable airtight baffle and is electrically connected to the control mechanism 6.

[0041] Furthermore, the isotope fluid tracing underground rock mass geological early warning device also includes a guide rod 5, which is mounted on the protective cylinder 1 and used to drive the protective cylinder 1 to move up and down. Through the cooperation of the protective cylinder 1 and the guide rod 8, the guide rod moves up and down, thereby driving the protective cylinder 1 to move up and down.

[0042] To better understand the technical solution of this embodiment, the working principle of the isotope fluid tracing underground rock mass geological early warning device is explained as follows:

[0043] The central control module 7 issues control commands, and the control mechanism 6 receives the commands and opens the control switch 12. The isotope tracer material fluid in the storage tank 2 enters the rock pores through the extendable rubber tube 10. When the pressure value of the pressure pointer reaches 5 MPa, the control mechanism 6 controls the foldable airtight baffle to open, forming a sealed space at the lower end of the extendable rubber tube 10 to prevent the isotope tracer material fluid from diffusing into the protective cylinder 1, ensuring that the isotope tracer material fluid flows into the rock pores and fissures using liquid diffusivity. The data acquisition module 5 tracks and measures the path and distance of the isotope tracer material fluid through the isotope probe and the ranging sensor. The display module 72 displays the data, and the processing module 71 processes the data and summarizes it to the host 73. Then, the host 73 understands the diffusion of the isotope tracer material fluid, thereby clarifying the basic development status of the underground rock mass. By pressurizing again, the joint development status of the deep rock mass can be understood.

[0044] The isotope fluid tracing underground rock mass geological early warning device, in the event of a mine accident, the processing module 71 processes the data in the display module 72 and transmits the detected geological conditions to the host 73 for display. This helps people quickly and accurately understand the location and condition of fractures, and then select appropriate support techniques for early support treatment of the fractures, thereby ensuring the smooth progress of underground geotechnical engineering construction and minimizing worker casualties.

[0045] like Figure 2 As shown in the embodiments of this application, an early warning system is also proposed, including a mining car body 100 and a remote control and central data processing device 108 for remotely controlling the mining car body 100 to carry out mining operations. The mining car body 100 is equipped with the isotope fluid tracer underground rock mass geological early warning device as described above. The mining car body 100 is also equipped with:

[0046] The positioning and travel recording device 101 is used to record the position of the mine car body 100 in real time. Specifically, the mine car body 100 is also equipped with a 5G communication device 107 that works in conjunction with the positioning and travel recording device 101.

[0047] The position sensing and monitoring distance device 102 is used to detect the distance between the mine car body 100 and the external environment in real time;

[0048] The weighing device 103 is used to measure the weight of coal or coal gangue loaded on the mine car body 100.

[0049] The lighting warning device 104 is electrically connected to the positioning and travel recording device 101, the position sensing and monitoring distance device 102, and the weighing device 103 respectively, and provides lighting warnings based on the real-time status of the three. Specifically, when the mine car body 100 is in a safe condition, the lighting warning device 104 emits yellow light, and when a warning occurs, the lighting warning device 104 changes from yellow light to red light.

[0050] A voice warning device 105 is electrically connected to the light warning device 104 and cooperates with the light warning device 104 to broadcast warnings.

[0051] The power unit 106 is used to drive the mining car body 100 to move.

[0052] To better understand the technical solution of this embodiment, the working principle of the mining truck is explained as follows:

[0053] Before the mining vehicle body 100 operates, it first checks the power status of the power unit 106. If the power is below 20%, it will promptly remind the user to charge. After the power unit 106 has finished charging, the voice warning device 105 will promptly remind the user to fully charge, and then the power unit 106 will automatically disconnect the power.

[0054] Upon entering the mine, the positioning and travel recording device 101 and the 5G communication device 107 are activated to record the travel and position of the mine car body 100 in real time.

[0055] Upon arrival at the bottom of the mine shaft, the isotope fluid tracer for underground rock mass geological early warning is activated to clarify the basic development status of the underground rock mass and understand the joint development of the deep rock mass. Then, based on the basic conditions of the rock mass, the driving route of the mine car body 100 is determined. The remote control and central data processing device 108 and the position sensing and monitoring distance device 102 are activated, remotely controlling the mine car body 100 to travel on the prescribed route and maintain an appropriate distance from other mine cars, reaching the designated working face for loading coal or gangue.

[0056] When loading coal or gangue in the roadway, the weighing device 103 and the partition it is located on are activated; the partition is lowered to the top of the working face to facilitate the loading and transportation of coal or gangue by miners. When the weight reaches the set safety value, the light warning device 104 changes from yellow to red, and the voice warning device 105 issues a warning for the corresponding situation. After coal loading is completed, the partition returns to its original position.

[0057] When transporting coal or gangue in the tunnel, when the distance between the mine car bodies 100 reaches the set safety value, the light warning device 104 changes from yellow light to red light, and at the same time the voice warning device 105 issues a warning for the corresponding situation. Then, the distance between the mine car bodies 100 is adjusted by the remote control and central data processing device 108 until the mine car bodies 100 reach the safe distance.

[0058] When the mine car body 100 passes through the coal bunker at the bottom of the mine, the remote control and central data processing device 108 will open the partition where the weighing device 103 on the mine car body 100 is located to carry out the coal unloading operation.

[0059] When the mine car body 100 arrives at the coal gangue storage bin, the remote control and central data processing device 108 will slowly open the partition where the weighing device 103 is located to carry out the coal gangue unloading operation. At this time, the light warning device 104 changes from yellow light to red light, and the voice warning device 105 will issue a warning for the corresponding situation to avoid injury to mine workers.

[0060] By remotely controlling the isotope fluid tracer for underground rock mass geological early warning device and system, unmanned underground operations can be initially realized; by remotely controlling the isotope fluid tracer for underground rock mass pore and fracture early warning device, the route design of underground mine cars can be optimized; by remotely controlling the partition on the weighing device 103, loading and unloading of coal and gangue can be facilitated; in case of emergencies involving underground mine cars, intelligent early warning will issue audible and visual alarm signals to ensure that personnel do not enter dangerous areas and minimize casualties; by using the positioning and travel recording device 101 to locate and record the travel of the mine cars in real time, the mine cars can be prevented from being abandoned, effectively avoiding emergencies such as mine car runaway and loss of control; by using the position sensing and distance monitoring device 102 and The weighing device 103 monitors the load and spacing of the mine cars to prevent overloading and effectively avoid collisions. The 5G communication device 107 periodically uploads data such as mine car working time, load, abnormal situations, and driving trajectories to the network center, and compares this data with project progress and extraction rate or mining ratio to analyze abnormal data and develop a reasonable work schedule, thereby improving project progress. The lighting warning device 104 and the voice warning device 105 provide timely warnings of mine car accidents, preventing psychological trauma to mine workers. This effectively improves work efficiency, ensures personal, property, and equipment safety, and effectively reduces the operating costs of mine construction, thus promoting the continued healthy development of the coal mining industry.
