Abstract
Description
Technical Field
[0001] This invention relates to the field of determining the distribution morphology of land leachate, and in particular to a monitoring device for the distribution morphology of land leachate. Background Technology
[0002] In-situ leaching (ISL) is a process in which a specially formulated leachate is injected into an underground aquifer through injection boreholes. The leachate undergoes a chemical reaction to dissolve uranium, which is then pumped to the surface through extraction boreholes to extract the uranium metal. ISL technology is commonly used in the mining of sandstone-type uranium, gold, or copper deposits. After entering the aquifer, the leachate diffuses through the voids or fissures in the sandstone strata, gradually forming a leachate diffusion zone within the aquifer. The leachate diffusion zone plays a crucial role in ISL projects: firstly, the extent of the diffusion zone's coverage over the ore body determines the leaching rate / recovery rate; secondly, monitoring and controlling the boundary of the diffusion zone is essential for meeting environmental protection requirements in ISL mines; and thirdly, the size and shape of the diffusion zone determine the injection and extraction volumes, directly impacting economic indicators.
[0003] Currently, the industry's methods for monitoring the diffusion distribution zone of leachate are still in a relatively rudimentary stage. They primarily rely on traditional well-site boundary monitoring boreholes for the ore-bearing aquifer, combined with overlying vortex monitoring boreholes within the well site, to conduct basic monitoring of the leachate diffusion boundary and vertical flow of leachate. This traditional and basic monitoring method is far behind the rapid development and technological iteration of in-situ leaching technology, particularly in the following aspects:
[0004] First, the current development trend of in-situ leaching mines is rapidly moving towards digital and intelligent mines. However, the traditional monitoring well sampling and analysis method, as a means of monitoring the diffusion distribution zone of leachate, cannot provide a digital data system or be connected to the digital mine control network that is being planned and constructed. This has obviously become a shortcoming in the digital and intelligent development of in-situ leaching mines.
[0005] Secondly, the timeliness and manual workload of water sampling and chemical analysis through monitoring wells are practical and difficult problems to be solved in in-situ leaching mines. As the mining area expands, the time for water sampling and the number of samples for chemical analysis will increase significantly. The number of analytical personnel, instruments, sampling personnel, vehicles and equipment required will also increase sharply, and the contradiction between timeliness and manual workload will become more and more intense.
[0006] Furthermore, relying solely on well sampling analysis makes it difficult to generate visualized results for mine operation decisions. The analysis results need to be compared with well location distribution maps, which is highly incompatible with the highly visualized, end-to-end operation guided by the digitalization and intelligentization of current mine production processes. Operators find it difficult to quickly and comprehensively grasp the real-time distribution of underground solutions across the entire mining area and all mining zones. Summary of the Invention

[0061] This embodiment provides a monitoring device for the distribution pattern of leachate in a ground-oriented manner, and the usage process is as follows:
[0062] 1. In the central control room of the integrated well-to-ground power supply excitation device unit at the immersion well site, use the integrated power supply cable (3) to connect the integrated dedicated power supply unit (1) in the central control room to the current field transmitter (2); use the excitation cable to connect the excitation end interface of the transmitter (2) through the central control room to the connection position on the metal sleeve of the power supply excitation well (5) and use a multimeter to measure the grounding resistance between it and the transmitter. It should not be greater than 1000 ohms. Otherwise, the connection process needs to be repeated until it is less than 1000 ohms. Use the excitation cable to connect the remote power end interface of the transmitter (2) through the central control room to the remote power supply excitation well (5). The electrode (4) is connected and the far electrode (4) is set at a distance of 300-500 meters from the power supply excitation well (5) outside the well site. Generally, a copper metal cone polarization electrode is used as the far electrode (4), with a length of not less than 40cm. When placing the electrode, the tip of the metal cone head must be buried at least 30cm below the ground, and 10cm of the cone must be left above the ground. A certain amount of 5% salt water should be poured into the electrode burial site regularly. The grounding resistance between the electrode and the transmitter should be measured with a multimeter and should not be greater than 1000 ohms. Otherwise, the connection and burial steps of the far electrode (4) need to be repeated until it is less than 1000 ohms.
[0063] 2. In the control room of the integrated signal receiving and processing unit for the immersion well site, a general power supply device (6) is integrated and connected to the electrode potential signal receiving device via a power supply cable. The integrated signal receiving and processing unit for the immersion well site is connected to the acquisition computer (7) via a power supply cable. The electrode potential signal receiving device is connected to the acquisition computer (7) via a LAN connection cable (10). The distributed electrode potential signal receiver (8) installed in the electrode potential signal receiving device passes through the control room via an electrode wire and connects to the non-electrode signals distributed in the well site. Connect the polarized electrode (11). The non-polarized electrode (11) needs to be placed in the electrode pit at the well site. The depth of the electrode pit should be at least 30cm. After placing the non-polarized electrode (11), pour in 5% salt water until the water level submerges half of the electrode. Then backfill the soil and compact the electrode pit. Use a multimeter to measure the grounding resistance between any two electrodes. The grounding resistance should not be greater than 1000 ohms. Otherwise, repeat the above electrode burial steps until the grounding resistance is less than or equal to 1000 ohms. Regularly pour a certain amount of 5% salt water into the upper layer of the electrode pit.
[0064] 3. Connect the bus switch (12) located in the central control room of the entire plant area to the acquisition computer (7) in the central control room of each well site through the LAN connection cable (10), and then connect the bus switch (12) to the calculation inversion workstation (13) through the data exchange LAN cable (10).
[0065] 4. Turn on the switch of the integrated dedicated power supply unit (1) in the central control room, and measure the resistance between the remote electrode (4) and the metal casing of the power supply excitation well (5) to ensure that it is less than 1000 ohms. After the voltage and current stabilize, turn on the current field transmitter (2) and transmit the current field signal between the well and the ground through the dipole source device composed of the remote electrode (4) and the metal casing of the power supply excitation well (5).
[0066] 5. After the excitation device has been turned on for about 20 minutes in the previous step and the excitation signal has stabilized, turn on the switch of the integrated ordinary power supply device (6) in the central control room of each acquisition well site, turn on the switch of the electrode potential signal receiving device, and turn on the acquisition computer (7). Observe the connectivity and stability of each channel signal through the acquisition software on the acquisition computer (7). If there is a problem that the channel signal value is too large or too small or is obviously abnormal compared to other channel signal values, it is necessary to check the electrode line, electrode, and electrode installation of that channel, find the problem, and re-install and connect until the channel signal is normal. After checking and confirming that there are no errors, turn on the acquisition software switch of the acquisition computer (7) and start data acquisition.
[0067] 6. Turn on the bus switch (12) and turn on the calculation inversion workstation (13). Set the data cutoff point according to the requirements, import the cutoff data segment into the calculation inversion software to select the one-dimensional, two-dimensional or three-dimensional calculation inversion method, set the cutoff error, set the number of iterations, set the fitting parameters, click Start Inversion, and wait for the calculation to end to obtain the inversion result.
[0068] This invention features a high degree of digitalization, with all equipment and operations except for the excitation end being completed by the acquisition computer and the computational inversion workstation, resulting in a fully digital process; it also boasts a high degree of visualization, capable of generating one-dimensional, two-dimensional, and three-dimensional visualization result models; it is highly time-efficient, requiring only a few hours from the emission of the excitation signal to obtaining the inversion result, which is much more time-efficient than traditional sampling chemical analysis; and it is highly automated, significantly reducing labor costs.
