[0002] The statements herein are provided only as background information in connection with this application and do not necessarily constitute prior art.

[0003] The identification of fault structures is of great significance for uranium exploration. By identifying fault structures, explorers can find areas where uranium deposits may exist based on geological conditions that are conducive to uranium formation, and thus select key areas for exploration.

[0004] High-density electrical resistivity tomography (EDS) is a commonly used exploration method for identifying fault structures. Through EDS, explorers can quickly, accurately, and easily identify fault structures at their locations. This method provides information on the spatial distribution, depth, and dip of fault structures, facilitating geological interpretation and borehole site selection. Summary of the Invention

For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.

[0014] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0015] High-density electrical resistivity tomography (EDT) is a common detection method used in uranium exploration to identify ore-bearing fracture structures. However, this method has high requirements for electrode grounding conditions, requiring the grounding resistance of the area to be detected to be stable and within a reasonable range. When the grounding resistance is unstable, it will prevent explorers from obtaining accurate data; when the grounding resistance is too high, the underground power supply current will be too low, resulting in the inability to reach the required detection depth.

[0016] In existing technologies, high-density electrical resistivity tomography (EDT) uses ordinary chopstick-shaped pure copper steel rods as electrodes. Surveyors increase conductivity by pouring saturated brine into the area to be measured. However, during continuous power supply, as the brine evaporates, the grounding resistance and current change, making it impossible for surveyors to obtain accurate and stable data, thus leading to deviations in the description of the electrical structure of the geological body.

[0017] To address the aforementioned problems, embodiments of this application provide an electrode device suitable for uranium exploration, comprising: a conductive component, an electrode, and a water-conducting component. The conductive component is configured to be inserted underground into the area to be explored in the uranium exploration and to conduct current from an external power source underground to form the electric field required for measurement. The electrode is configured to be fixedly connected to the conductive component, and the conductive component and the electrode are detachably disposed within the water-conducting component. The water-conducting component is configured to provide saturated brine to the underground medium at the measurement location in the area to be explored, thereby reducing the grounding resistance at that location.

[0018] The embodiments of this application allow for the detachable connection of conductive components, electrodes, and water-conducting components. This enables surveyors to use the conductive components and electrodes to introduce external current into the ground, forming the electric field required for measurement. Then, through the connected water-conducting components, saturated brine is supplied to the ground to reduce the resistance at the measured location, resulting in more accurate measurement data.

[0019] See Figure 1 , Figure 1 This is a schematic diagram of the structure of a conductive component according to an embodiment of this application. In some embodiments, such as Figure 1 As shown, the conductive component includes a conductive element 1, an elastic fixing element 2, and a support element 3. The support element 3 is fixedly connected to the conductive element 1 and is configured to support the electrode. The elastic fixing element 2 is fixedly connected to the conductive element 1 and is configured to elastically fix the electrode to the conductive element 1.

[0020] In the embodiments of this application, a conductive element 1 is provided to conduct current to the ground, providing the electric field required for measurement. The elastic fixing element 2 and the support element 3 fix the electrode to the conductive element 1, increasing the stability of the electrode fixation and preventing the electrode from falling off during the measurement process, thus avoiding the inability to obtain accurate measurement data.

[0021] In some embodiments, the conductive member 1 includes a force-receiving part 11 and a conductive part 12. The force-receiving part 11 is fixedly connected to the conductive part 12 so that when it moves under the action of an external force, it can drive the conductive part 12 to insert into the ground of the area to be explored. The conductive part 12 is configured to conduct the current of an external power source into the ground to form the electric field required for measurement. The elastic fixing member 2 is fixedly connected to the conductive part 12. The support member 3 is fixedly connected to the conductive part 12.

[0022] With this configuration, the conductive component 1 includes a force-receiving part 11 and a conductive part 12, which facilitates the exploration personnel to insert the conductive component into the underground of the area to be explored by applying force to the force-receiving part 11. The elastic fixing part 2 and the support part 3 are fixedly connected to the conductive part 12, which helps to fix the electrode on the conductive part 12, so that the electrode can conduct current into the underground of the exploration area through the conductive part 12.

[0023] In some embodiments, the elastic fastener 2 includes an elastic part 21 and a plurality of fasteners 22. The plurality of fasteners 22 are respectively disposed at both ends of the elastic part 21. The plurality of fasteners 22 are configured to be fixedly connected to the conductive member 1. The elastic part 21 is configured to elastically fix the electrode to the conductive member 1.

[0024] By setting multiple fixing parts 22 in this way, when fixing the electrode, the connection between one of the fixing parts 22 and the conductive member 1 can be disconnected, the electrode can be placed on the support member 3, and then the fixing part 22 can be connected to the conductive member 1 to fix the electrode to the conductive member 1; by elastically fixing the electrode to the conductive member 1 through the elastic part 21, the structure can be simplified and it is easier for surveyors to carry and assemble.

[0025] See Figure 2 , Figure 2 This is a schematic diagram of the structure of a water-guiding assembly according to an embodiment of this application. In some embodiments, such as Figure 2 As shown, the water guiding component includes a water supply component 6, a flow control component 5, and a water guiding component 4. The water supply component 6 is configured to hold saturated brine and is fluidly connected to the water guiding component 4 through the flow control component 5. The flow control component 5 is configured to control the flow rate of the saturated brine flowing from the water supply component 6 into the water guiding component 4. The water guiding component 4 is configured to provide saturated brine to the underground medium at the measurement location in the area to be explored. The conductive components and electrodes are detachably installed inside the water supply component 6.

[0026] This configuration ensures that the water supply component 6 continuously provides sufficient saturated brine to the water guide component 4. By controlling the flow rate of the saturated brine supply component 5, the saturated brine supply rate can be controlled, preventing the water guide component 4 from losing saturated brine due to prolonged measurement and providing a stable environment rich in saturated brine for measurement.

[0027] In some embodiments, the water supply component 6, the flow control component 5, and the water guide component 4 are connected by an insulated connecting pipe.

[0028] This setup ensures that the pipes through which the saturated brine flows are made of insulating materials, thus preventing additional current from interfering with the measurement results.

[0029] In some embodiments, the water supply component 6 is made of insulating material.

[0030] This design ensures that the container for storing saturated brine is made of insulating material, thus preventing additional current from interfering with the measurement results.

[0031] In some embodiments, the flow control element 5 is composed of insulating material and is gravity-driven without the need for a power source.

[0032] This configuration ensures that the flow control element 5 is made entirely of insulating material and does not use a power source to drive the flow rate control, thus avoiding the introduction of additional current from outside the measurement field, which could interfere with the measurement results.

[0033] In some embodiments, the water guide 4 is formed as a tubular member, and the wall of the tubular member has multiple holes, which are used to provide saturated brine to the underground medium at the measurement location of the area to be explored. The conductive components and electrodes are detachably disposed inside the tubular member.

[0034] This setup allows for the supply of saturated brine to the underground medium at the measurement location through multiple holes, enabling the tubular component to continuously supply saturated brine to the underground medium and reducing the grounding resistance of the underground medium in the area to be measured.

[0035] In some embodiments, the radial dimension of the tubular member is greater than a predetermined value of the radial dimension of the portion of the conductive component disposed in the tubular member.

[0036] This design ensures that surveyors can insert the conductive component into the tubular part, and the gap between the conductive component and the tubular part is filled with saturated brine to ensure that the saturated brine can flow smoothly from the water supply component 6 to the water guide component 4.

[0037] In some embodiments, the tubular member forms a protrusion to allow it to be inserted into the ground.

[0038] This design creates a sharper protrusion on the tubular component, increasing the pressure when inserted into the ground under the same pressure. This allows the tubular component to be inserted into the ground to its maximum depth, increasing the contact area for current to flow into the underground medium and reducing the grounding resistance.

[0039] To facilitate understanding, the usage process of this device will be further explained.

[0040] The device provided in this application includes a conductive component, electrodes, and a water-conducting component. Before conducting measurements, surveyors need to assemble and prepare the device, insert the conductive component into the water-conducting component, align the entire device with the specific ground location to be measured, and then insert the device into the ground for measurement.

[0041] In some embodiments, the conductive component includes a conductive element 1, an elastic fixing element 2, and a supporting element 3. The conductive element 1 includes a force-receiving part 11 and a conductive part 12. When the surveyor inserts the device into the ground, he can use a hammer to strike the force-receiving part 11 so that the entire device can be inserted into the ground.

[0042] In some embodiments, the water guiding assembly includes a water supply component 6, a flow control component 5, and a water guiding component 4. In order to reduce the resistivity of the area to be explored, the explorer fills the water supply component 6 with saturated saline solution and completely removes the conductive component from the water guiding assembly. The flow control component 5 is opened, and the saline solution in the water supply component 6 is introduced into the water guiding component 4, filling the water guiding component 4 with saturated saline solution. The conductive component is then reinserted into the water guiding assembly, and the force-receiving part 11 is pressed to completely fill the water guiding assembly with the conductive component.

[0043] In some embodiments, the elastic fixing member 2 includes an elastic part 21 and a plurality of fixing parts 22, and the support member 3 includes two copper plates rigidly connected longitudinally and laterally. To secure the electrode to the conductive component, the explorer opens the fixing parts 22 of the elastic fixing member 2 and places the electrode above the transverse copper plate of the support member 3. The elastic part 21 is then pulled open, and the fixing parts 22 are fitted onto the conductive part 12, ensuring the electrode is fixed to the conductive component. At this point, the electrode device suitable for uranium exploration is assembled and prepared; the next step is measurement.

[0044] During measurement, surveyors supply power to the electrodes through the main unit of the high-density electrical resistivity tomography (EDT) equipment, test the grounding resistance, and collect data. The water-conducting component 4 is formed as a tubular structure, with five holes in its wall. These holes supply saturated brine to the underground medium at the measurement location in the area to be surveyed. The conductive components and electrodes are detachably installed inside the tubular structure. Surveyors control the flow control component 5 to adjust the rate at which the water supply component 6 provides saturated brine. The saturated brine flows out from the holes in the tubular structure's wall, continuously supplying saturated brine to the area to be measured, reducing the impact on the periphery of the tubular structure's insertion into the underground portion. The grounding resistance is within a certain range.

[0045] During the long-term data collection process, the surveyors need to pay attention to the water level of water supply unit 6. If the water level is lower than the working level, saturated saline solution needs to be added in time to ensure that a stable saturated saline solution environment is provided for the area to be measured during the measurement process.

[0046] After completing the above steps, remove the entire device to collect data at the next measurement point. Repeat all the assembly preparation and measurement steps above until data collection at all measurement points is completed.

[0047] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.
