Description

Technical Field

[0001] This invention relates to the field of mining technology, specifically to a high-concentration tailings conveying equipment system for rare metal ore backfilling mining. Background Technology

[0002] In the field of rare metal mining, backfilling mining has become one of the mainstream mining techniques due to its ability to effectively control the deformation of the surrounding rock, reduce the land area occupied by tailings ponds, and lower the risk of surface subsidence. High-concentration tailings transportation is a core component of backfilling mining, requiring the tailings from mineral processing to be processed to a specific concentration before being transported via pipelines to the goaf for backfilling. With the increasing national requirements for ecological environmental protection in mines, the leaching of heavy metals, the concentration of suspended solids in the slurry, and the concentration of VOCs generated by the volatilization of flotation reagents during tailings transportation must all strictly comply with environmental standards. This necessitates that high-concentration tailings transportation not only ensures transportation efficiency and stability but also simultaneously meets the needs of environmental monitoring and control. Therefore, the improvement of related technologies is of great significance for the green mining of rare metals.

[0003] Traditional high-concentration tailings conveying systems often employ a segmented design. Environmental parameter monitoring relies on independent sensors for manual data reading, while conveying parameter adjustment is based on operator experience, lacking real-time linkage. For example, if heavy metal leaching exceeds the standard, manual shutdown and flocculant dosage adjustment are required; if suspended solids concentration is too high, the pipeline shear speed must be manually increased. This not only results in delayed response but also easily leads to fluctuations in conveying efficiency. Furthermore, the system lacks a unified intelligent control and monitoring unit, with environmental data scattered across different devices, making full-process traceability difficult. Regulatory authorities cannot monitor the conveying status in real time. Additionally, the pre-compression components in traditional tailings pretreatment units are poorly deployed, exhibiting poor adaptability to rare metal ore tailings with different characteristics, easily leading to uneven tailings compression that affects subsequent conveying.

[0004] This invention is primarily applied to rare metal ore backfilling mining scenarios, including tantalum-niobium mines, lead-zinc mines, and tungsten mines, which have high-concentration tailings transportation requirements. Addressing the challenges of coordinating environmental monitoring, parameter control, and compliance supervision in these mines' backfilling mining processes, the integrated equipment system provided by this invention can be directly integrated into existing backfilling mining production lines. It achieves a closed-loop operation of the entire process—tailings pretreatment, environmental monitoring, intelligent control, and compliance supervision—without large-scale modifications to existing equipment. It is particularly suitable for mines with stringent environmental requirements and complex tailings characteristics, effectively solving problems such as insufficient adaptability and lagging supervision in traditional systems. This provides technical support for rare metal mining enterprises to meet ecological and environmental protection requirements and improve the stability of backfilling mining, helping mines achieve green and sustainable mining. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a high-concentration tailings conveying equipment system for rare metal ore backfilling mining. This system eliminates data interference through a moving average algorithm and achieves quantitative linkage between environmental parameters and conveying parameters based on three types of linkage formulas, generating precise control commands. Simultaneously, it constructs a closed-loop system encompassing "monitoring-control-early warning-supervision." This effectively solves the problems of disconnected monitoring and control, scattered data, and lagging supervision in traditional systems, improving the environmental compliance and stability of tailings conveying, enhancing adaptability to tailings with different characteristics, reducing operation and maintenance costs, and providing reliable technical support for green and sustainable backfilling mining of rare metal mines.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-concentration tailings conveying equipment system for rare metal ore backfilling mining, the system comprising:

[0007] Tailings pretreatment unit: includes tailings storage structure and precompression components, used to receive rare metal ore tailings and precompress the tailings through the precompression components;

[0008] Environmental parameter monitoring unit: includes multiple monitoring components, used to collect data on the amount of heavy metals leached from tailings, the concentration of suspended solids in slurry, and the concentration of volatile organic compounds at conveying nodes;

[0009] Tailings conveying unit: The feed end is connected to the discharge end of the tailings pretreatment unit, including a conveying pump, a pipe shear and a spraying system, used to receive tailings pretreated by the tailings pretreatment unit and complete the filling and conveying of high-concentration tailings.

[0010] Intelligent control unit: It establishes signal connections with the environmental parameter monitoring unit and the tailings conveying unit respectively. Its signal input terminal is connected to the signal output terminal of the environmental parameter monitoring unit, and its control signal output terminal is connected to the control signal input terminal of the tailings conveying unit. It is used to receive various environmental parameters collected by the environmental parameter monitoring unit, filter the collected parameters, and then calculate the corresponding control parameters through the heavy metal-pump pressure-flocculator linkage formula, the suspended solids-shear rate linkage formula, and the VOCs-spray volume linkage formula. In turn, it generates conveying pump pressure adjustment command, flocculant dosage adjustment command, pipeline shear speed adjustment command, and spray volume control command to form a complete conveying control closed loop.

[0011] Regulatory docking unit: Establishes a signal connection with the intelligent control unit to receive environmental parameters, calculation results, control instructions and equipment operation-related data transmitted by the intelligent control unit, encrypts and stores the received data, and uploads the relevant data to the external regulatory platform.

[0012] Furthermore, the pre-compression component of the tailings pretreatment unit is a plurality of components, which are evenly distributed circumferentially along the top of the tailings storage structure. Each pre-compression component applies pre-pressure to the tailings synchronously, and the shape of the pressure surface of the pre-compression component is adapted to the shape of the top opening of the tailings storage structure.

[0013] Furthermore, multiple monitoring components of the environmental parameter monitoring unit are respectively deployed at the outlet of the tailings pretreatment unit, the middle section of the pipeline of the tailings conveying unit, and around the pump body of the tailings conveying unit.

[0014] Furthermore, the calculation formula for the heavy metal-pump pressure-flocculator linkage is as follows: , ;in, This is for adjusting the pump pressure. This refers to the adjustment rate for flocculant dosage. Real-time heavy metal leaching data collected by the environmental parameter monitoring unit; This refers to the standard threshold for heavy metal leaching. This refers to the mineral type compatibility coefficient. This is the basic correction value for pump pressure.

[0015] Furthermore, the formula for calculating the suspended matter-shear rate linkage is as follows: ,in, The target rotational speed of the pipe shear; This refers to the base rotational speed of the shear; Real-time suspended solids concentration collected by the environmental parameter monitoring unit; This represents the standard threshold for suspended solids concentration.

[0016] Furthermore, the VOCs-spraying volume linkage calculation formula is as follows: ,in, This refers to the amount of surfactant sprayed. Real-time concentration of volatile organic compounds collected by the environmental parameter monitoring unit; This refers to the standard threshold for the concentration of volatile organic compounds. This represents the emission inhibition coefficient for volatile organic compounds.

[0017] Furthermore, when the calculated control parameters exceed the preset range, the intelligent control unit sends an abnormal warning signal to the regulatory docking unit in real time. The regulatory docking unit then uploads the abnormal warning signal and corresponding data to the external regulatory platform.

[0018] Furthermore, the intelligent control unit filters the collected parameters using a moving average algorithm. By setting a data collection window of a fixed size, it performs an arithmetic mean calculation on multiple sets of data collected by the environmental parameter monitoring unit within the window. The mean of the current window is used as the valid data to replace the original instantaneous data within the window, thereby eliminating interference data caused by tailings flow fluctuations and sensor instantaneous response deviations, providing stable and accurate input parameters for the subsequent calculation of the linkage formula.

[0019] Compared with existing technologies, this high-concentration tailings conveying equipment system for rare metal ore backfilling mining has the following advantages:

[0020] I. This invention constructs an integrated system comprising a tailings pretreatment unit, an environmental parameter monitoring unit, a tailings conveying unit, an intelligent control unit, and a regulatory docking unit. Relying on the moving average algorithm and three types of linkage formulas of the intelligent control unit, it forms a precise control logic, effectively solving the problem of disconnect between environmental monitoring and parameter control in traditional high-concentration tailings conveying. The moving average algorithm can eliminate interference data caused by tailings flow fluctuations and instantaneous sensor deviations, providing stable input for the heavy metal-pump pressure-flocculator linkage formula, the suspended solids-shear rate linkage formula, and the VOCs-spraying volume linkage formula. The three types of formulas achieve a quantitative correlation between environmental parameters and conveying parameters, allowing dynamic adjustment of pump pressure, flocculant dosage, shear speed, and spraying volume without manual intervention. This ensures that the heavy metal leaching, suspended solids concentration, and VOCs concentration meet standards during tailings conveying, while avoiding fluctuations in conveying efficiency, thus improving the environmental friendliness and stability of high-concentration tailings backfilling mining.

[0021] Second, this invention overcomes the limitations of traditional tailings conveying systems, such as scattered data and lagging supervision, by using a signal linkage and parameter anomaly early warning mechanism between the intelligent control unit and the regulatory docking unit, combined with the multi-node deployment design of the environmental parameter monitoring unit. When the intelligent control unit exceeds the preset range of the control parameters, it can simultaneously send an anomaly warning signal to the regulatory docking unit. The regulatory docking unit stores all data through encryption and uploads it to an external regulatory platform, realizing full-process traceability of "monitoring-control-early warning-supervision". At the same time, the circumferential uniform distribution of the pre-compression components of the tailings pretreatment unit and the targeted deployment of the environmental parameter monitoring components further improve the system's adaptability to the characteristics of tailings from different rare metal ores, reduce the increase in operation and maintenance costs caused by insufficient equipment adaptability, and meet the actual needs of long-term stable operation of mine backfilling mining.

[0025] Figure 2 This is a framework diagram of a high-concentration tailings conveying equipment system. Detailed Implementation

[0026] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0027] Example 1:

[0028] This embodiment is applied to an underground backfilling mining operation at a large tantalum-niobium mine. The site employs backfilling mining to treat goaf areas, requiring the transport of high-concentration tailings generated after ore beneficiation to a depth of 1200 meters underground for backfilling. The high-concentration tailings conveying equipment system for rare metal ore backfilling mining of this invention is installed as a whole within the mine's tailings treatment workshop and underground conveying tunnels. The implementation steps are as follows: Figure 1 As shown:

[0029] The tailings pretreatment unit's tailings storage structure is a cylindrical silo with a diameter of 10 meters. Four pre-compression components are evenly arranged circumferentially on the top of the silo. When tantalum-niobium tailings are conveyed into the tailings storage structure by the conveyor belt, the four pre-compression components start simultaneously and apply pre-pressure to the tailings, causing the tailings to be initially compressed within the silo, reducing voids in the tailings and preventing slurry stratification during subsequent transportation.

[0030] Multiple monitoring components of the environmental parameter monitoring unit are deployed at the discharge port of the tailings pretreatment unit, the middle section of the pipeline of the tailings conveying unit, and around the conveying pump. The monitoring components deployed at the discharge port continuously collect the amount of heavy metal leaching in the tailings, the monitoring components deployed in the middle section of the pipeline continuously collect the concentration of suspended solids in the slurry, and the monitoring components deployed around the pump continuously collect the concentration of volatile organic compounds at the conveying nodes. All collected parameter data are transmitted to the intelligent control unit in real time.

[0031] After receiving various data transmitted from the environmental parameter monitoring unit, the intelligent control unit uses a moving average algorithm to filter the data. This algorithm sets a fixed-size continuous data acquisition window, calculates the arithmetic mean of multiple sets of continuous data within the window, and uses the mean as the valid data, eliminating interference data caused by tailings flow fluctuations and sensor instantaneous response deviations. Subsequently, based on the processed valid data, the intelligent control unit calculates the corresponding control parameters using the heavy metal-pump pressure-flocculator linkage formula, the suspended solids-shear rate linkage formula, and the VOCs-spray volume linkage formula, respectively. It then generates pump pressure adjustment commands, flocculant dosage adjustment commands, pipeline shearer speed adjustment commands, and spray volume control commands, sending these commands to the tailings conveying unit in real time. The heavy metal-pump pressure-flocculator linkage calculation formula is as follows: , ;in, This is for adjusting the pump pressure. This refers to the adjustment rate for flocculant dosage. Real-time heavy metal leaching data collected by the environmental parameter monitoring unit; This refers to the standard threshold for heavy metal leaching. This refers to the mineral type compatibility coefficient. This is the basic correction value for pump pressure; the formula for calculating the linkage between suspended solids and shear rate is: ,in, The target rotational speed of the pipe shear; This refers to the base rotational speed of the shear; Real-time suspended solids concentration collected by the environmental parameter monitoring unit; The standard threshold for suspended solids concentration; the formula for calculating the linkage between VOCs and spray volume is: ,in, This refers to the amount of surfactant sprayed. Real-time concentration of volatile organic compounds collected by the environmental parameter monitoring unit; This refers to the standard threshold for the concentration of volatile organic compounds. This represents the emission inhibition coefficient for volatile organic compounds.

[0032] The feed end of the tailings conveying unit is connected to the discharge port of the tailings pretreatment unit via a pipeline to receive the pretreated high-concentration tailings. Upon receiving instructions from the intelligent control unit, the conveying pump adjusts its working pressure according to the pump pressure adjustment instruction to ensure stable flow of tailings within the conveying pipeline; the flocculant dosing device adjusts the flocculant dosage according to the flocculant dosage adjustment instruction to promote the adsorption of heavy metal ions in the tailings; the pipeline shear adjusts its rotation speed according to the pipeline shear speed adjustment instruction to disperse any suspended agglomerates that may form in the slurry; and the spraying system adjusts the surfactant spray flow rate according to the spray volume control instruction to suppress the diffusion of volatile organic compounds around the conveying pump body.

[0033] The monitoring and control unit maintains a real-time signal connection with the intelligent control unit, continuously receiving environmental parameters, control parameter calculation results, various control commands, and equipment operating status data transmitted by the intelligent control unit. After encrypting the received data, the monitoring and control unit stores a portion of the data in its local storage module, while the remaining data is uploaded to the local mine ecological environment monitoring platform according to a standardized transmission protocol. When the control parameters calculated by the intelligent control unit exceed the preset range, the intelligent control unit sends an abnormal warning signal to the monitoring and control unit in real time. The monitoring and control unit then uploads this abnormal warning signal along with the corresponding data to the monitoring platform, enabling monitoring personnel to promptly grasp the on-site operating conditions and intervene.

[0034] In summary, this embodiment applies the equipment system of the present invention to a tantalum-niobium mine backfilling mining scenario at a depth of 1200 meters. Addressing the stability and environmental compliance requirements of deep-ground tailings transportation, it achieves uniform pretreatment of tailings through a cylindrical silo and four circumferentially distributed pre-compression components. A multi-node environmental parameter monitoring unit accurately collects data on heavy metal leaching, suspended solids concentration, and VOCs concentration. After data processing using a moving average algorithm by the intelligent control unit, control commands are generated based on the heavy metal-pump pressure-flocculator linkage formula, the suspended solids-shear rate linkage formula, and the VOCs-spraying volume linkage formula. These commands drive the coordinated operation of all components in the tailings transportation unit. Simultaneously, a monitoring and docking unit enables encrypted data storage and anomaly reporting. The entire system is adapted to deep-ground tailings transportation conditions in tantalum-niobium mines, effectively solving the problem of disconnect between monitoring and control in traditional systems. It ensures tailings transportation efficiency while meeting environmental standards, providing reliable technical support for deep-ground rare metal mine backfilling mining.

[0035] Example 2:

[0036] This embodiment is applied to a medium-sized lead-zinc mine's open-pit to underground backfilling mining operation. The tailings of this mine contain a certain amount of lead ions, zinc ions, and volatile flotation reagent residues, which places high demands on the environmental compliance of the tailings transportation process. The high-concentration tailings transportation equipment system for rare metal ore backfilling mining of this invention is deployed and operated as follows:

[0037] The tailings storage structure of the tailings pretreatment unit is a rectangular silo with three pre-compression components evenly arranged along the length of the silo top. After dewatering, the lead-zinc mine tailings are fed into the tailings storage structure by a scraper conveyor. The three pre-compression components synchronously adjust the pressure according to the accumulation characteristics of the lead-zinc mine tailings, so that the tailings form a uniform compressed layer in the silo, reducing the fluctuation of the moisture content of the tailings during subsequent transportation.

[0038] The monitoring components of the environmental parameter monitoring unit are deployed as follows: A monitoring component is installed at the outlet of the tailings pretreatment unit to collect the leaching amounts of lead and zinc ions in the tailings; a monitoring component is installed in the middle section of the main conveying pipeline of the tailings conveying unit to collect the concentration of suspended solids in the slurry; and monitoring components are installed near the inlet and outlet of the conveying pump and around the flotation reagent addition points to collect the concentration of volatile organic compounds in the surrounding environment. Each monitoring component transmits the collected parameter data to the intelligent control unit in real time. The transmission process uses an industrial-grade bus communication protocol to ensure the stability and real-time performance of data transmission.

[0039] After receiving the data, the intelligent control unit first processes it using a moving average algorithm. Considering the significant fluctuations in heavy metal ion concentrations in lead-zinc mine tailings, the size of the data acquisition window is appropriately adjusted to ensure the accuracy of the data. After processing, the intelligent control unit calculates the corresponding control parameters using the heavy metal-pump pressure-flocculator linkage formula, the suspended solids-shear rate linkage formula, and the VOCs-spray volume linkage formula. Based on the environmental standards of the lead-zinc mine, it generates appropriate instructions for adjusting the conveying pump pressure, flocculant dosage, pipeline shear speed, and spray volume, and sends these instructions to the tailings conveying unit.

[0040] The tailings conveying unit uses a three-cylinder single-acting plunger pump. Upon receiving a pump pressure adjustment command, the pump pressure is smoothly adjusted via a hydraulic system to prevent pipeline vibration caused by sudden pressure changes. The flocculant dosing device uses a metering pump, which precisely controls the flocculant dosing rate according to the flocculant dosage adjustment command to ensure that lead ions, zinc ions, and flocculants react fully. The blades of the pipeline shear are evenly distributed along the main shaft, and the rotation speed is changed in real time according to the rotation speed adjustment command to effectively break up suspended particles in the slurry. The spray head of the spray system is directed towards the sealing part of the conveying pump and the flotation reagent volatilization area. The spray range and flow rate are adjusted according to the spray volume control command to suppress the escape of volatile organic compounds.

[0041] The local storage module of the monitoring and docking unit uses high-capacity storage media to store received environmental parameters, calculation results, control commands, and equipment operation data for a long period of 90 days, facilitating subsequent data traceability and operational analysis. Simultaneously, the monitoring and docking unit uploads encrypted data to the provincial mine environmental monitoring platform in real time. When the pump pressure or volatile organic compound concentration approaches the preset upper limit, an abnormality alert signal sent by the intelligent control unit triggers the monitoring and docking unit's priority upload mechanism, ensuring the monitoring platform receives abnormal information immediately and guaranteeing the environmental compliance and safety of lead-zinc mine backfilling operations. The overall framework of the system is as follows: Figure 2 As shown.

[0042] In summary, this embodiment applies the equipment system of the present invention to the open-pit to underground backfill mining scenario of lead-zinc mines. Addressing the characteristics of lead-zinc mine tailings containing heavy metal ions and volatile reagents, the system adapts to the tailings accumulation characteristics through a rectangular silo and three pre-compression components. Environmental monitoring nodes are set focusing on heavy metal leaching and VOCs concentration. The intelligent control unit adjusts the data processing window based on the fluctuation characteristics of lead-zinc mine tailings parameters, generates precise control commands based on three types of linkage formulas, and achieves stable adjustment of delivery parameters with components such as plunger pumps and metering pumps. The regulatory docking unit ensures data traceability and compliant supervision through 90-day long-term storage and an anomaly priority upload mechanism. The system is fully adapted to the high environmental protection requirements of lead-zinc mines, effectively controls heavy metal and VOCs pollution, solves the problems of poor adaptability and lagging supervision of traditional systems, and helps lead-zinc mines carry out backfill mining operations safely and compliantly.
