Description

Technical Field

[0001] The present invention relates to the technical field of in-situ leaching liquid injection, and in particular to a method and system for adaptively controlling the timing and intensity of in-situ leaching liquid injection by partitions. Background Art

[0002] The in-situ leaching process involves laying out injection holes on the surface of the ore block, constructing a liquid collection system with a ore-free zone or waterproof bottom plate at the bottom, and injecting the leaching agent from the high-level pool into the ore body through the injection pipeline. After the leaching agent reacts with the mineral, the solution carries the target components and migrates to the collection pool under the guidance of the liquid collection system. The core efficiency of this process directly depends on the reasonable layout of the injection system and the precise control of the leaching process. However, the traditional process has significant bottlenecks: the layout of the injection system mainly relies on empirical judgment and lacks scientific theoretical guidance; the control of the injection process is highly dependent on manual supervision, usually following the "three firsts" principle of "up first, then down; concentrated first, then diluted; liquid first, then water."

[0003] This extensive model leads to a double dilemma: On the one hand, improper injection parameter settings and inaccurate control can easily lead to uneven leaching of the ore body. Localized "under-leaching" creates blind spots, while localized "over-leaching" can cause slope instability and trigger geological hazards such as landslides or landslides. On the other hand, manual control is labor-intensive, with one or two people often working in shifts around the clock on a single ore block. These workers face harsh conditions and high safety risks, exposed to the sun, rain, mosquitoes, and loneliness in steep terrain and overgrown vegetation. Therefore, there is an urgent need to develop an innovative method that can scientifically guide injection layout, precisely optimize the control process, and significantly reduce labor intensity in harsh environments.

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] The following describes a method and system for adaptively controlling the timing and intensity of injection of liquid in situ leaching zones according to an embodiment of the present invention with reference to the accompanying drawings.

[0022] See also Figures 1 to 7 To achieve the above-mentioned purpose, the method for adaptively controlling the timing and intensity of injection of liquid in situ leaching zones of the present invention comprises: Step S10, obtaining terrain data and slope partitions of the area to be mined; Step S20, determining a number of injection blocks based on the terrain data and slope partitioning; Step S30, determining the watershed position and the ridgeline position respectively according to the terrain data; Step S40, determining a number of injection holes 2 in each injection block according to the topographic data; Step S50, determining a fluid injection plan based on the terrain data, the watershed location, and the ridgeline location; Step S60 , arranging the injection pipelines 1 in each injection area according to the injection plan so that the injection pipelines 1 are arranged from high to low along the elevation, and sequentially inject liquid into each injection hole 2 in the injection block to a preset liquid level.

[0023] Through scientific zoning, automatic control of injection timing and intensity adaptive compensation mechanism, the leaching efficiency is effectively improved, the intensity of manual intervention and the operating risks in harsh environments are significantly reduced, and safety issues in the leaching process are effectively avoided, providing an advanced injection method with strong theoretical support, simple operation and economic feasibility for in-situ leaching.

[0024] The present invention aims to achieve three core objectives: first, to significantly improve leaching uniformity and resource recovery efficiency, eliminate "under-leaching" blind spots and suppress the risk of slope instability caused by "over-leaching"; second, to significantly reduce the reliance on manual supervision and labor intensity in harsh environments; and third, to get rid of the reliance on monitoring equipment for massive basic data.

[0025] This invention is suitable for in-situ leaching of deposits, such as weathering crust elution deposits. Application of this invention can increase the leaching rate of valuable elements in the mining area by more than 10%, while significantly reducing labor intensity by more than 50%. Furthermore, it effectively suppresses geological disasters such as slope instability, collapse, and landslides induced by the leaching process, reducing their frequency by more than 50%, thereby significantly improving the efficiency and safety of the in-situ leaching process.

[0026] In a second embodiment of the present invention, based on the first embodiment, the terrain data includes the elevation of the ore block, the slope of the ore block, and the vertical strike width of the ore block. This data collection provides a basis for subsequent slope zoning and the calculation of watershed and ridgeline locations.

[0027] In a third embodiment of the present invention, based on the first embodiment, the slope is divided into a mild zone, a moderately steep zone, a steep zone, and a steeply steep zone based on the slope of the steep side of the ridgeline of the area to be mined. The mild zone has a slope greater than or equal to 0° and less than 15°, the moderately steep zone has a slope greater than or equal to 15° and less than 25°, the steep zone has a slope greater than or equal to 25° and less than 35°, and the steep zone has a slope greater than or equal to 35° and less than 90°. Mineral blocks are divided along the ridgeline to facilitate zoning operations in multiple injection zones based on operational difficulty, thereby improving operational efficiency.

[0028] In a fourth embodiment of the present invention, based on any one of the first to third embodiments, step S30 includes: Step S31 , according to the terrain data, with the steep slope side of the ridge line as the starting point of the x-axis and the direction toward the gentle slope side as positive, respectively determine the watershed position and the ridge line position.

[0029] In order to reduce the risk of landslides on the steep slope during mining in the area to be mined, the steep slope side of the ridgeline is used as the starting point of the x-axis (i.e., the 0 point position), and the watershed position is "pushed" toward the steep slope side (positive towards the gentle slope side).

[0030] The watershed position is smaller than the ridgeline position, that is, x ws < x rl .

[0031] In the fifth embodiment of the present invention, based on the fourth embodiment, the calculation formula of the watershed position is as follows: ; in, x ws It represents the location of the watershed under injection recharge, in m; l Indicates the vertical strike width of the block, in m; K Indicates the permeability coefficient of the ore block, in m / s; W Indicates the infiltration intensity, which refers to the infiltration recharge per unit horizontal area and per unit time, with the unit being m / s; h 1 represents the water head of the liquid collection project on the steep slope side of the ridge line, in m; h 2 represents the water head of the liquid collection project on the gentle slope side of the ridge line, in m.

[0032] In the sixth embodiment of the present invention, based on the fourth embodiment, the calculation formula of the ridgeline position is as follows: ; in, x rl Indicates the projection position of the ridge line on the horizontal plane, in meters; α 1 indicates the slope on the steep side of the ridgeline; α 2 indicates the slope on the gentle side of the ridgeline.

[0033] In a seventh embodiment of the present invention, based on any one of the first to third embodiments, step S60 includes: Step S61, arrange the injection pipelines 1 in each injection area according to the injection plan so that the injection pipelines 1 pass through the vertical injection pipes 22 in each injection hole 2 from high to low in elevation, and inject liquid into each injection hole 2 in its injection block to a preset liquid level.

[0034] In the eighth embodiment of the present invention, based on the seventh embodiment, the calculation formula for the length of the vertical injection tube 22 extending into the injection hole 2 is as follows: ; in, H p It represents the length of the vertical injection pipe 22 extending into the injection hole 2, in meters; L t Indicates the height of the injection hole 2 relative to the reference plane, in meters; H w Indicates the height of the water head in the injection hole 2 relative to the reference surface, in meters; H e It represents the height of the far-field water head relative to the reference plane, in meters; r w Indicates the radius of the injection hole 2, in m; R Indicates the influence radius, in meters.

[0035] To achieve the above objectives, the present application also provides an adaptive control system for the timing and intensity of liquid injection for in-situ leaching. The control system applies any of the above-mentioned adaptive control methods for the timing and intensity of liquid injection for in-situ leaching, and the control system includes: high pool; A vertical injection pipe 22 in each injection hole 2, and a float valve mechanism 5 is provided at one end of each injection pipe close to the bottom of the injection hole 2; A connecting pipe 8, one end of which is connected to the high-level tank; At least one liquid injection pipeline 1, one end of each liquid injection pipeline 1 is connected to the connecting pipeline 8, and each liquid injection pipeline 1 is connected to the vertical liquid injection pipe 22 in each liquid injection hole 2 from high to low along the elevation; A flow monitoring module 4 is provided on the connecting pipeline 8 and each liquid injection pipeline 1. The flow monitoring module 4 is used to monitor the flow data of the connecting pipeline 8 and the flow data of each liquid injection pipeline 1; The electric adjustment module 3 is provided on the connecting pipeline 8 and each injection pipeline 1, and is used to control the flow of the connecting pipeline 8 and each injection pipeline 1; The control module communicates signals with the flow monitoring module 4 and the electric control module 3 respectively. The control module is used to control the electric control module 3 according to the flow data so that the injection pipeline 1 moves from high to low in elevation, and injects liquid into each injection hole 2 in the injection block to a preset liquid level in turn.

[0036] A conical anti-seepage cover 21 is provided at the opening of each injection hole 2. The conical anti-seepage cover 21 is located at the connection between the vertical injection pipe 22 and the injection pipeline 1. The conical anti-seepage cover 21 is sleeved on the outer wall of the vertical injection pipe 22, and the open end of the conical anti-seepage cover 21 is in sealed contact with the mineral soil at the opening of the injection hole 2 to prevent rainwater from seeping in.

[0037] Specifically, the number of liquid injection blocks is positively correlated with the number of liquid injection pipelines 1 , and at least one liquid injection pipeline 1 is provided in the liquid injection block.

[0038] Specifically, the gap between the conical anti-seepage cover 21 and the outer wall of the vertical liquid injection pipe 22 is between 0.5 mm and 1 mm.

[0039] Differentiated injection flow control is implemented for each zone, and the leaching agent is led from the high-level pool along the ridge line to the injection block to be mined through injection pipeline 1, and the leaching agent is led to each injection block through injection pipeline 1 at the highest altitude of each injection block.

[0040] At the connection point between the high-level tank and the connecting pipeline 8, as well as at the connection point between the connecting pipeline 8 and each injection pipeline 1, an electric adjustment module 3 (i.e., an electric control valve) and a flow monitoring module 4 (i.e., a flow sensor) are connected in series. The electric adjustment module 3 and the flow monitoring module 4 are both connected to the control module signal.

[0041] The control module controls the electric adjustment module 3 based on the preset flow parameters and the flow data detected by the flow monitoring module 4, controls each injection pipeline 1, and realizes the regulation of the injection flow of multiple injection blocks.

[0042] A siphon network is constructed by the electric adjustment module 3, the flow monitoring module 4, the connecting pipeline 8, the injection pipeline 1 and each vertical injection pipe 22 to achieve stepped injection of the injection block from top to bottom.

[0043] Injection pipelines 1 are installed on both sides of the ridgeline in each injection block and laid horizontally along the ridgeline to the mouth of each injection hole 2. Injection holes 2 are arranged from top to bottom according to the elevation gradient. The diameter of injection holes 2 ranges from 10 cm to 18 cm. The horizontal projection of adjacent injection holes 2 forms a "plum blossom" shape. The hole spacing multiplied by the row spacing ranges from 1.5 m x 1.5 m to 2.0 m x 2.0 m.

[0044] Specifically, the injection pipeline 1 comprises several branch pipelines 11, arranged in descending order from highest to lowest elevation. The ends of each branch pipeline 11 are located near the boundaries of the injection block, and adjacent branch pipelines 11 are connected by vertical siphon pipes 12. This cycle continues until the injection holes 2 at the lowest elevation are fully covered. The injection pipelines 1 on both sides of the ridgeline within the injection block form a stepped siphon network, following this principle.

[0045] The vertical siphon pipe 12 is used to drain the leaching agent in the branch pipe 11 in the current elevation plane of the two adjacent branch pipes 11 to the branch pipe 11 in the next elevation plane of the two adjacent branch pipes 11 .

[0046] The branch pipeline 11 after the lowering is laid horizontally in the opposite direction and is connected to the vertical injection pipes 22 in each injection hole 2 in the elevation surface in sequence. The extension direction of the branch pipeline 11 after the lowering is opposite to the branch pipeline 11 at the previous elevation, forming an interlaced layout path when viewed from above.

[0047] Specifically, the float valve mechanism 5 includes an outer ring water inlet 51 , an inner ring water outlet 52 , a rubber sealing plug 54 , a sealing cavity 6 , a connecting rod 73 and a float 74 .

[0048] A float 74 is disposed within the float chamber 7 and can slide freely up and down. It is connected to a connecting rod 73 at the bottom of the sealed chamber 6 via a flexible wire 75. A rubber plug 76 is provided near the bottom of the sealed chamber 6. A compression spring 63 and a filter screen 64 are located within the sealed chamber 6. A first exhaust port 61 is defined at the top of the sealed chamber 6, while a second exhaust port 62 is defined at the bottom. The compression spring 63 passes through the first exhaust port 61 and is securely connected to the rubber sealing plug 54. A third exhaust port 72 is defined at the top of the float chamber 7 to remove air from the chamber 7 and maintain pressure equilibrium between the chamber 7 and the injection port 2.

[0049] During injection, the leachate enters through the outer ring water inlet 51 of the float valve mechanism 5 and presses down the rubber sealing plug 54. The leachate then flows from the inner ring water outlet 52 of the float valve mechanism 5 through the drain port 53 into the injection hole 2. The air contained in the leachate is discharged through the first exhaust port 61 and the second exhaust port 62 to maintain air pressure balance. At this time, the float 74, under the action of gravity, pulls down the connecting rod 73 through the flexible thin wire 75, so that the second exhaust port 62 remains open.

[0050] When the liquid level in the injection hole 2 rises to submerge the connecting water inlet 71 of the floating chamber 7, the float 74 floats up and pushes the connecting rod 73 upward, and the rubber plug 76 blocks the second exhaust port 62; the air pressure in the sealed chamber 6 increases accordingly, and through the coordinated force of the air pressure, the rebound force of the compression spring 63 and the negative pressure of the inner ring water outlet 52, the rubber sealing plug 54 moves upward to close the inner ring water outlet 52 and terminate the injection.

[0051] When the liquid level in the injection hole 2 drops, the float 74 falls back to drive the connecting rod 73 to return to the original position and open the second exhaust port 62, and the rubber sealing plug 54 falls to resume injection.

[0052] The beneficial effects of the present invention also include: Safety assurance is significantly improved. Slope zoning is used to avoid injection overload in steep slope areas, and the float valve mechanism 5 is coordinated to suppress the saturation of local injection holes 2. The siphon network formed by the injection pipeline 1 and each vertical injection pipe 22 is used to achieve siphon step injection to block the advanced seepage of the lower ore body, forming a triple protection mechanism of "zoning load limitation - steady flow to prevent saturation - time-series pressure control", which significantly reduces the risk of pore water pressure accumulation and shear slippage, and ensures the stability of the slope during the leaching process.

[0053] The labor intensity is significantly reduced. Relying on the siphon network, the "first up and then down" sequential injection is independently executed. The float valve mechanism 5 realizes the adaptive stability of the injection intensity, avoids the dependence on monitoring equipment and massive monitoring data, and achieves adaptive regulation; the conical anti-seepage cover 21 simultaneously blocks the interference of precipitation, eliminates the need for emergency response to heavy rain and manual calibration of the injection intensity, and realizes the goal of unmanned operation throughout the entire process.
