Description

Technical Field

[0001] The present application relates to the technical field of water supply and drainage, and in particular to a scheduling method for underground mining water supply and drainage and related equipment. Background Art

[0002] During the mining process, a large amount of mine drainage water is inevitably produced due to the existence of underground fissures and water systems. In order to ensure normal production underground, this drainage water must be discharged to the surface through a pump station. However, this drainage water is a precious water resource. If it is not recycled, it will cause serious waste of resources. Therefore, it is critical to use underground drainage water for production purposes such as mining and mineral processing. Although the traditional water supply and drainage system can achieve basic drainage and water supply functions, it is difficult to achieve the reasonable allocation and balance of water resources, and the level of automation control is low, the operation is complex, and the efficiency is low.

[0003] In addition, due to the complexity of the mine's water supply and drainage system, which involves underground and surface water resource management and scheduling, the points are wide and difficult to control. Traditional manual operations are difficult to respond to underground production needs in real time, and also increase labor costs. In order to meet these challenges, an efficient and intelligent water supply and drainage scheduling method is urgently needed to achieve efficient utilization and intelligent management of mine water supply and drainage through automated control, thereby improving resource utilization efficiency, reducing waste, and realizing an unmanned intelligent mine operation mode.

[0044] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0045] See also Figure 1 , which is a flowchart of a method for scheduling water supply and drainage in a mine provided in an embodiment of the present application, which may specifically include:

[0046] S110, collecting the underground drainage water into an underground water tank, and controlling the start and stop of the underground drainage pump based on a first monitoring value, wherein the first monitoring value is monitored based on a first liquid level controller of the underground water tank;

[0047] For example, during the mining process, groundwater inevitably collects in the mine through natural infiltration or due to underground cracks, rock formation gaps, etc., forming a large amount of drainage water. If this drainage water cannot be discharged in time, it may cause the underground working environment to be slippery or even waterlogged, seriously affecting the normal operation of underground equipment and the safety of personnel. Therefore, a collection point, i.e., a water tank, needs to be set up underground to collect this drainage water and further discharge it to the surface through a water pump.

[0048] The site selection and construction of the water tank are crucial. Generally, it is selected in the low-lying area of ​​the mine to facilitate natural confluence and smooth collection of drainage water. At the same time, the capacity design of the water tank should be reasonably planned according to the daily water inflow of the mine and the water inflow under extreme conditions to ensure that there is no overflow under normal production conditions and that it can effectively cope with peak periods.

[0049] In order to realize the automatic management of drainage water, a high-precision first liquid level controller is set in the water tank. The controller monitors the water level changes in the water tank in real time and gives the corresponding liquid level signal as the basis for controlling the start and stop of the drainage pump. Specifically, the liquid level controller generally has multiple liquid level thresholds, and each liquid level value corresponds to a different water pump start and stop strategy.

[0050] S120, draining the underground drainage water to a surface water reservoir, and controlling the start and stop of a surface water supply pump based on a second monitoring value, wherein the second monitoring value is monitored based on a second liquid level controller of the surface water reservoir;

[0051] For example, in the water supply and drainage system of a mine, the underground drainage water needs to be transported to the surface water reservoir after being collected and preliminarily treated in the underground water tank. The function of the surface water reservoir is to temporarily store the drainage water for underground production, mineral processing operations and subsequent water recycling. The underground drainage water is usually transported to the surface water reservoir through the main drainage pipe and the underground drainage pump. The design of the drainage pipe needs to take into account the depth of the mine, the flow rate and flow rate of the drainage water to ensure that the water can be discharged from the mine quickly and efficiently.

[0052] In the process of delivering underground drainage water to the surface, the stable operation of the drainage system must be ensured. To this end, multiple water pumps are usually used to operate in stages and transport water to different heights through a main pipeline and auxiliary pipeline network to overcome the elevation difference between the mine and the surface.

[0053] The surface water reservoir is an important part of the entire water supply and drainage system, mainly used to collect and store the drainage water transported from the underground. The reservoir not only provides water for underground production and mineral processing, but also can extract heat or cold from it through the water source heat pump system for the air conditioning and heating system inside the mine.

[0054] The design of the water reservoir needs to consider its capacity and location. In terms of capacity, it must be able to accommodate the total amount of long-term drainage water from the mine and leave sufficient overflow space to cope with the peak of water inrush under extreme weather conditions. In terms of location, the water reservoir should be close to the mine dressing area and the underground water supply system to reduce the water supply transportation distance and save energy and maintenance costs.

[0055] In order to ensure the efficient operation of the surface water storage tank, a second liquid level controller is installed in the water storage tank to monitor the liquid level in the water storage tank in real time and automatically control the start and stop of the surface water supply pump according to the change of the liquid level. The liquid level controller usually sets multiple water level thresholds to automatically adjust the working state of the water pump according to the water level conditions.

[0056] S130, transporting excess underground drainage water to a water return circulation tank, and controlling the start and stop of a water return pump based on a third monitoring value, wherein the third monitoring value is monitored based on a third liquid level controller of the water return circulation tank.

[0057] For example, during the underground mining process, underground drainage water is collected and transported to the surface reservoir. When the water level in the surface reservoir exceeds a certain high water level threshold, the excess water can no longer be stored in the reservoir, so an additional water storage device is required to temporarily store the water. At this time, the return water circulation tank serves as a temporary water storage device to store excess underground drainage water and transport it back to the system for production when needed.

[0058] The delivery of drainage water is generally achieved through a water supply pump and pipeline system. The drainage water is pumped from the surface water storage tank to the return water circulation tank. The key to this process is to be able to flexibly adjust the water flow to ensure that the water can be effectively stored and put back into use when needed, so as to achieve efficient use of water resources.

[0059] The return water circulation tank is an important buffer facility of the water supply and drainage system. Its main purpose is to receive excess drainage water and reserve it for subsequent use when the surface water storage tank is operating at full capacity. The return water circulation tank usually has a certain water storage capacity. The actual water demand and water volume fluctuation of the mine need to be considered during the design to ensure effective water resource allocation during peak hours.

[0060] The water in the return water circulation pool is mainly used to supplement the water for underground production or ore dressing production, and can also be used as a backup water source for the entire mine water supply and drainage system. When the demand for water in the ore dressing plant or underground production is high, the water in the return water circulation pool can be transported back to the water supply system through the return water pump to ensure the continuity of production.

[0061] In order to achieve accurate control of the water level in the return water circulation tank, a third liquid level controller is installed in the tank, which can monitor the water level changes in the circulation tank in real time and adjust the start and stop status of the return water pump according to different water level thresholds. The third liquid level controller usually has two main water level monitoring values ​​to automatically control the operation of the return water pump according to the water level conditions.

[0062] In summary, the embodiments of the present invention provide a method for scheduling water supply and drainage in underground mines, which transforms traditional manual operations into automated management by introducing liquid level controllers for underground, surface and return water systems. This automated liquid level monitoring and control technology greatly reduces the complexity of manual operations while ensuring the safety and stability of the water supply and drainage system. For mines, especially when water supply and drainage demands fluctuate at any time, an automatic control system that can respond to water level changes in real time can greatly improve the efficiency of the entire mine production process and ensure the continuity and production safety of underground operations.

[0063] In some examples, the method of controlling the start and stop of the downhole drainage pump based on the first monitoring value, wherein the first monitoring value is monitored based on the first liquid level controller of the downhole water tank, includes:

[0064] The first liquid level controller includes a first downhole water level value, a second downhole water level value and a third downhole water level value, wherein the first downhole water level value is greater than the second downhole water level value, and the second downhole water level value is greater than the third downhole water level value;

[0065] When the first monitoring value is greater than the first downhole water level value, a first number of downhole drainage pumps are started to operate;

[0066] When the first monitoring value is greater than the second downhole water level value and less than or equal to the first downhole water level value, starting a second number of the downhole drainage pumps;

[0067] When the first monitoring value is greater than the third downhole water level value and less than or equal to the second downhole water level value, starting a third number of the downhole drainage pumps;

[0068] When the first monitoring value is less than or equal to the third downhole water level value, the downhole drainage pump is stopped;

[0069] Among them, the above-mentioned first number is greater than the above-mentioned second number, and the above-mentioned second number is greater than the above-mentioned third number.

[0070] For example, a first liquid level controller is set to monitor the water level in the underground water tank, and the working state of the underground drainage pump is automatically adjusted according to different water level values, so as to realize intelligent management of underground drainage water. Based on real-time monitoring of the water level, the system can dynamically start or stop different numbers of drainage pumps to ensure that the underground water level is within a safe range while minimizing energy consumption and equipment wear.

[0071] In this system, the first liquid level controller is the core component, responsible for real-time monitoring of the water level changes in the underground water tank. The liquid level controller usually has three main water level thresholds, namely the first underground water level value, the second underground water level value and the third underground water level value. These water level values ​​correspond to different control strategies, which are used to control the start and stop of the drainage pump. The monitoring system ensures rapid drainage at high water levels to prevent water accumulation in the mine, and stops the pump at low water levels to avoid idling or excessive energy consumption.

[0072] When the water level in the underground water tank exceeds or reaches the first underground water level value, this water level value represents the upper limit of the water tank. When the water level reaches or exceeds this threshold, the system will automatically start the first number of underground drainage pumps, that is, the maximum number of pumps configured by the system, to quickly lower the water level and prevent the water tank from overflowing. This strategy is suitable for sudden water inrush or excessive water accumulation during underground production, and can quickly restore the water level to a safe level.

[0073] When the water level in the underground water tank is between the second underground water level value and the first underground water level value, the number of drainage pumps activated by the system is the second number, which is less than the number of pumps at the first underground water level, but sufficient to maintain a normal drainage speed. The purpose of this strategy is to reduce energy consumption and avoid excessive drainage while maintaining normal production.

[0074] When the water level in the underground water tank is between the third underground water level value and the second underground water level value, the system only starts the third number of drainage pumps, that is, the minimum number of pumps. At this time, the system maintains the basic water level in the water tank through low-frequency drainage, which not only avoids idling of the equipment, but also ensures that the water level does not rise to a dangerous level too quickly.

[0075] When the water level in the underground water tank is lower than the third underground water level value, the system will stop all underground drainage pumps to prevent the pumps from idling in the absence of water and prevent equipment damage. At the same time, this strategy also ensures that a certain amount of water is retained in the water tank as a possible water reserve for future use. In actual operation, the system dynamically adjusts the number of drainage pumps according to different water level values ​​to adapt to water level changes. This flexible control of the number of pumps can significantly improve the efficiency of the system and ensure that the appropriate drainage speed is maintained when the water level fluctuates at different times.

[0076] When the water level drops from the first well water level to the third well water level, the system will stop all drainage pumps to prevent the water pumps from continuing to operate and causing the water level in the water tank to drop excessively. However, when the water level drops from the first well water level to the second well water level, the system will not immediately stop some pumps. The reason for this is that frequent starts and stops will cause greater wear and tear on the pump equipment and shorten its service life. Therefore, in the process of slowly dropping the water level, keeping a certain number of pumps in continuous operation can not only ensure that the water level gradually returns to a safe range, but also avoid the risk of failure caused by excessive load and frequent startup of the equipment. In this way, the system effectively extends the service life of the pump and reduces maintenance and replacement costs.

[0077] On the basis of the above-mentioned liquid level monitoring and pump start-stop strategy, the underground water supply and drainage of the present invention realizes an intelligent, unattended water supply and drainage management system through the linkage control of the liquid level controller and the drainage pump. Its key control principles include:

[0078] According to the water level in the water tank, the system automatically adjusts the working state and number of drainage pumps to ensure that the drainage speed matches the actual water level changes. For example, when there is a sudden influx of water, all pumps are started to drain water quickly, and when the water level is stable, the number of pumps is reduced to save energy; during the water level change process, the system does not frequently start and stop the pumps, but adjusts the drainage speed by gradually reducing or increasing the number of pumps. This method can effectively reduce the wear and tear of the equipment caused by frequent starting of the water pump and extend the service life of the pump. Since the system can dynamically adjust the working state of the pump according to the real-time water level changes, it ensures that the pump is started only when needed, thereby reducing unnecessary energy consumption. This intelligent control mechanism can minimize energy usage costs while ensuring safe production.

[0079] In some examples, the method of controlling the start and stop of the surface water supply pump based on the second monitoring value, wherein the second monitoring value is monitored based on the second liquid level controller of the surface water reservoir, includes:

[0080] The second liquid level controller includes a first surface water level value, a second surface water level value and a third surface water level value, wherein the first surface water level value is greater than the second surface water level value, and the second surface water level value is greater than the third surface water level value;

[0081] When the second monitoring value is greater than the first surface water level value, the underground drainage pump is stopped, and the surface water supply pump is started to replenish water to the return water circulation pool;

[0082] When the second monitoring value is greater than the second surface water level value and less than or equal to the first surface water level value, the downhole drainage pump is stopped, and the surface water supply pump is stopped to replenish water to the return water circulation pool;

[0083] When the second monitoring value is greater than the third surface water level value and less than or equal to the second surface water level value, a water level early warning reminder is issued;

[0084] When the second monitoring value is less than or equal to the third surface water level value, the underground drainage pump is interlocked to replenish water to the surface water reservoir and the return water pump of the turnover tank is interlocked to supply water to the surface mineral processing production.

[0085] For example, the second liquid level controller monitors the water level change of the surface water reservoir, and automatically controls the start and stop of the surface water supply pump and the underground drainage pump according to different water level conditions. The intelligent control system ensures the reasonable distribution of water in the reservoir through multi-level water level monitoring and adjustment strategies, and realizes the efficient operation of the water supply and drainage system.

[0086] When the water level in the reservoir exceeds or reaches the first surface water level, the system will stop the underground drainage pump to prevent further water delivery to the reservoir. In addition, the system will start the surface water supply pump to deliver excess water to the return water circulation tank to ensure that the water level in the reservoir does not continue to rise and prevent overflow. The operation in this case is to reduce the burden on the reservoir and give priority to storing excess water in the circulation tank for backup.

[0087] When the water level drops to between the second surface water level and the first surface water level, the system stops the underground drainage pump and the surface water supply pump. This means that the water in the current reservoir is sufficient, and there is no need to continue to replenish the water source or to transport water to the return water circulation pool. At this time, the system is in a static state to maintain resource balance and minimize energy consumption.

[0088] When the water level drops to between the third surface water level value and the second surface water level value, the system issues a water level warning reminder to remind managers that the water level is too low and may affect subsequent production and water supply. At the same time, this water level value is used to trigger the system's automatic response mechanism to ensure that necessary operations are taken before the water level drops further.

[0089] When the water level is lower than or equal to the third surface water level value, the system will enter the emergency state, automatically interlock and start the underground drainage pump to replenish water to the reservoir, and start the return water pump of the return water circulation tank to supply water to the surface mineral processing production. This mechanism ensures that even under extreme conditions, the reservoir can still get the necessary water replenishment and maintain normal production operation. When the water level of the reservoir is too low, relying solely on the underground drainage pump to replenish water may not be able to immediately meet the water demand of mineral processing production. Therefore, the system will simultaneously start the return water pump of the return water circulation tank to re-transport the stored water in the return water circulation tank to the surface mineral processing production link. As an intermediate water storage facility for the entire system, the return water circulation tank is mainly used to receive and store excess underground drainage water during normal production. However, when the water level of the reservoir is insufficient, the return water circulation tank will act as a backup water source and provide the reserved water to the mineral processing production through the return water pump. This process can alleviate the emergency of insufficient water supply in a short time and ensure the uninterrupted water required for mineral processing production.

[0090] In some examples, it also includes:

[0091] After the underground drainage water is discharged to the above-mentioned surface water reservoir, it is used for underground mining production, water source heat pump extraction of heat or cold and surface mineral processing production water supply.

[0092] For example, the underground drainage water is collected in the water tank and then transported to the surface water tank through the drainage pump system. As the core water source storage unit of the system, the water tank can dynamically allocate water resources according to production needs to achieve various production and auxiliary purposes such as underground mining, ore dressing, and water source heat pump heating and cooling. This multifunctional use of water resources has greatly improved the resource utilization and operation efficiency of the mine water supply and drainage system.

[0093] Underground mining production usually requires a lot of water for cooling equipment, dust reduction, flushing and other operations. Through the water stored in the surface reservoir, the system can provide a stable water supply source to the underground production equipment. After preliminary sedimentation and treatment, the underground drainage water is reused in various production operations underground, which not only reduces the dependence on external water sources, but also realizes the recycling of water resources.

[0094] During this process, the liquid level controller monitors the water level of the surface water reservoir in real time and dynamically adjusts the water supply according to the needs of underground mining production. Water is transported to the underground working surface through a specially designed water supply pipeline system based on the siphon principle, ensuring that the required water can be continuously and stably provided at any stage of production.

[0095] The method utilizes the siphon principle to automatically supply water to the well, and interlocks the start and stop of the well drainage pump and the surface water supply pump based on the second monitoring value, including:

[0096] The siphon principle is a natural phenomenon based on liquid pressure difference, which can automatically transport water from high to low without external power. Specifically, when the water flow starts from the surface reservoir, due to the negative pressure formed in the pipe, the water can automatically flow through the pipe to the underground water supply point below the water surface. This process relies on the effect of gravity and water level difference, does not require additional water pump drive, and saves energy consumption.

[0097] In underground mining, the siphon principle is used to automatically provide a stable water supply to the underground water supply system. The water reservoir is located at a higher position on the surface, while the underground working surface is usually below the surface. Through a well-designed pipe system, the water forms a high head pressure in the water reservoir, so that the siphon effect can continuously transport water to the underground equipment, mine working area and other areas where water is needed.

[0098] The siphon water supply system is mainly composed of a water reservoir, a siphon pipe, a liquid level controller and a check valve. The water reservoir is located on the surface of the water reservoir and stores underground drainage water and other water resources. The liquid level of the water reservoir is monitored by a second liquid level controller, and the water supply and drainage are dispatched according to the monitoring value. The siphon pipe connects the water reservoir and the pipe of the underground water supply point. Through the pressure difference generated by the water level difference, the siphon pipe can automatically transport water without external power. The liquid level controller monitors the water level changes in the water reservoir, and interlocks the start and stop of the surface water supply pump and the underground drainage pump through the control system to ensure the balance and safety of the water supply system. The check valve prevents water from flowing back into the water reservoir when the siphon action stops, keeping the water flow in the pipe unidirectional.

[0099] In order to ensure the normal operation of the siphon system, the water inlet of the surface water reservoir must always be kept underwater. This state can effectively prevent air from entering the pipe from the water inlet, thus ensuring the continuous operation of the siphon principle. Therefore, it is crucial to manage the water level of the surface water reservoir, and it must be ensured that the water level does not fall below a certain critical value to prevent the water level from falling below the water inlet. The flooding of the water inlet not only ensures the normal water supply of the siphon system, but also avoids the possible introduction of gas in the pipeline, ensuring a stable water supply process.

[0100] When the water level in the surface water storage tank approaches the critical low water level, the system will automatically take water replenishment measures to ensure that the water level is maintained at an appropriate height. At this time, the system will interlock and start the underground pump station to replenish the drained water from the underground water tank to the surface water storage tank to keep the water level above the siphon water inlet. This operation can prevent the water inlet from being exposed to the air due to low water level, thereby ensuring the closure of the siphon pipeline and its continuous water supply capacity.

[0101] When the water level in the reservoir approaches the low water level threshold, the system will not only start the underground pump station to replenish water, but also suspend the replenishment of water to the return water circulation tank to give priority to the demand for siphon water supply. The return water circulation tank is mainly used as a reserve water source, usually used to receive excess water when the water in the reservoir is sufficient. However, under the premise of siphon water supply, the surface reservoir must give priority to maintaining a sufficient water level to ensure a stable water supply to the well. Therefore, when the water level is insufficient, the system will stop the water from the reservoir to the circulation tank to avoid unnecessary diversion of water resources.

[0102] This operation can give priority to maintaining the normal operation of the siphon system by using the water source of the surface water reservoir, and prevent the water level of the water reservoir from further decreasing due to diversion to the turnover tank. Through automatic control, when the system detects insufficient water level, it will give priority to all water sources for underground water supply and suspend any unnecessary water output to ensure the continuity of underground operations and the stability of siphon water supply.

[0103] The water source heat pump system utilizes the temperature characteristics of mine drainage water to extract heat to provide energy for heating in cold seasons, and can also extract cold energy for air conditioning and equipment cooling in hot seasons. At the same time, in order to further improve the energy utilization efficiency of the system, the system has added collaborative thermal management to recover the waste heat generated in the heat pump process and use it in mine heating or other process flows to maximize the recycling of energy.

[0104] As a stable heat / cold source, drainage water usually has a relatively constant temperature, especially in deep well areas, where the temperature remains at around 15-20°C all year round. This temperature stability provides ideal heat and cold source conditions for the efficient operation of the water source heat pump system.

[0105] In cold seasons, the water source heat pump system extracts heat from the warmer drain water and transfers it to the mine's production and office areas for heating. The specific working process is as follows:

[0106] The water source heat pump absorbs heat from the drained water through the evaporator, the temperature of the drained water is slightly reduced, and the temperature of the refrigerant inside the heat pump system is increased. The refrigerant is further heated up by the compressor and enters the heat exchanger to release the absorbed heat. Through heat exchange, the heat is transferred to the heating water system and used for heating the production area, living area or office area of ​​the mine. This process avoids the high energy consumption and high emissions of traditional boilers burning fossil fuels, and provides a clean and energy-saving solution for the mine's heating system. This heat pump heating can not only effectively improve the efficiency of heating, but also reduce the mine's dependence on external fuels for heating, achieving a lower carbon heating method.

[0107] In summer, the water source heat pump system can extract cold energy from the cooler drainage water for use in mine air conditioning systems or equipment cooling. The specific working principle is as follows:

[0108] When drain water passes through the evaporator, it transfers part of the cold to the heat pump system to cool the refrigerant in the system. After the refrigerant goes through the compression cycle, it releases the heat absorbed from the equipment or environment to the outside. Through this cooling process, the drain water lowers the temperature of the refrigerant and recirculates into the air conditioning and cooling equipment of the mine. By utilizing the stable low temperature characteristics of drain water, the air conditioning and cooling system can reduce dependence on electricity and save energy. This cooling mechanism can ensure the temperature control of the equipment and environment in the mine during the hot season, while reducing the energy consumption of the air conditioning system, providing efficient cooling support for the daily production of the mine.

[0109] To further improve the energy efficiency of the system, the water source heat pump system also adds a collaborative thermal management module to recover the waste heat generated by the heat pump system for use in mine heating or other process flows. Waste heat recovery can be achieved in the following ways:

[0110] When the heat pump system operates in cooling mode, the heat absorbed by the equipment and the environment can be used as waste heat, recovered and stored through the heat exchanger for the heating needs of the mine. This waste heat recovery can provide a stable heat source in cold weather, at night or during low-temperature operations. The mining production process requires high-temperature processes such as ore drying and evaporation. The waste heat generated by the heat pump system can be recovered and applied to these heating process flows, reducing the mine's demand for external heat sources and achieving energy recycling. When the waste heat in the system is not completely consumed, it can circulate in the pipeline and heat storage equipment to maintain its heat, and be released at any time when the mine production needs it, for the corresponding heating or process treatment.

[0111] By reusing the waste heat of the heat pump system, collaborative thermal management not only improves the overall energy efficiency of the mine's water supply and drainage system, but also significantly reduces the mine's operating costs. During heating or cooling, the recovered waste heat can reduce the mine's demand for external heat sources and achieve efficient recycling of heat within the mine. The waste heat recovery system can provide supplementary heat in a timely manner when the heating demand is peak or the heating system is unstable, ensuring the stable operation of the heating system and avoiding heating interruptions due to insufficient energy. The waste heat recovery of the heat pump system reduces the dependence on fossil fuels in traditional heating and heating methods, reduces the mine's carbon emissions, and enables the mine to meet environmental protection requirements and meet the sustainable development goals of energy conservation and emission reduction.

[0112] In addition to water used in underground mining, drainage water is also widely used in mineral processing. A large amount of water is required in the mineral processing process for operations such as ore screening, separation and cleaning. Through the surface water reservoir, the system can provide sufficient water for mineral processing production to ensure the smooth progress of mineral processing production. In this process, the system will adjust the working frequency of the water supply pump according to the production needs of the mineral processing plant to ensure the rational allocation of water resources. Through an efficient water resource scheduling mechanism, the system can dynamically adjust the allocation of water resources between underground mining and mineral processing production, giving priority to meeting the core needs of the production process.

[0113] In some examples, the control of the start and stop of the return water pump based on the third monitoring value, wherein the third monitoring value is based on the monitoring of the third liquid level controller of the return water circulation tank, includes:

[0114] The third liquid level controller includes a first circulating water level value and a second circulating water level value, wherein the first circulating water level value is greater than the second circulating water level value;

[0115] When the third monitoring value is greater than the first turnover water level value, the surface water supply pump is stopped to replenish water to the return water turnover pool, and the return water pump is operated;

[0116] When the third monitoring value is greater than the second turnover water level value and less than or equal to the first turnover water level value, the surface water supply pump replenishes water to the return water circulation pool, and the return water pump works;

[0117] When the third monitoring value is less than or equal to the second circulation water level value, the surface water supply pump replenishes water to the return water circulation tank and stops the return water pump.

[0118] Exemplarily, the start and stop of the return water pump is controlled by the third monitoring value to ensure that the water level of the return water circulation tank is always in a reasonable range, thereby achieving efficient operation of the system. The control process is based on the real-time monitoring of the water level of the return water circulation tank by the third liquid level controller, and by linking the start and stop of the surface water supply pump and the return water pump, it ensures that the system is dynamically regulated under different production needs and water level conditions.

[0119] The third level controller is installed in the return water circulation tank, which is mainly responsible for monitoring the water level changes in the tank to ensure that the water level is within the set safety range. This controller sets two main monitoring water level values, namely the first turnover water level value and the second turnover water level value. According to the different water levels in the return water circulation tank, the system will automatically adjust the working status of the surface water supply pump and the return water pump to ensure that the water volume in the return water circulation tank can be reasonably allocated.

[0120] When the third monitoring value shows that the water level in the return water circulation pool is greater than the first circulation water level value, the water volume in the return water circulation pool is sufficient, and the system will automatically stop the surface water supply pump to replenish water to the circulation pool to prevent the water level in the pool from continuing to rise to a dangerous level. At the same time, the return water pump starts to work and transports the excess water in the pool to other production links, such as the ore dressing plant or other areas that need water. At this time, the operation of the return water pump ensures the rational allocation of water resources and avoids the idleness and waste of water resources.

[0121] When the third monitoring value shows that the water level is between the second turnover water level value and the first turnover water level value, the system will continue to keep the surface water supply pump replenishing water to the turnover pool to ensure that the water level of the turnover pool is within the normal range. At the same time, the return water pump will continue to work and use part of the water for production purposes. In this case, the water supply pump and the return water pump work at the same time to ensure that both the water source can be replenished and the water demand can be met, realizing the dynamic allocation of water resources.

[0122] When the third monitoring value shows that the water level drops to or below the second turnover water level, it means that the water volume in the turnover pool is insufficient. At this time, the system will stop the return water pump and give priority to replenishing the water source in the turnover pool. The system automatically starts the surface water supply pump to replenish water to the return water turnover pool to ensure that the water level in the pool returns to a safe range. During the water replenishment process, the return water pump stops operating to avoid continuing to pump water when the water level is too low, preventing further reduction of water volume in the pool or loss caused by idling of equipment.

[0123] The return water circulation pool plays a key role in the transfer and regulation of the entire mine water supply and drainage system. Its main function is to store excess underground drainage water when water resources are sufficient as a backup water source for subsequent production water; when water is insufficient, it ensures production needs by supplementing water sources. At the same time, the system can dispatch water supply and drainage equipment through intelligent control under different water level conditions to optimize the balance between water supply and drainage.

[0124] In some examples, it also includes:

[0125] In the mine water supply and drainage system, the water level management of the underground water tank is particularly critical. The first control principle of the system is to give priority to the safety of underground drainage. When the water level of the underground water tank reaches the upper limit, that is, exceeds the set maximum water level (the first underground water level value), the underground main drainage pump will automatically start to prevent the water level from continuing to rise and ensure the safety of operations in the mine.

[0126] When the water level in the sump reaches the upper limit, the main drainage pump must be started and is not subject to any pump stop command. The system will continue to operate until the water level drops to the set safety level to ensure that the mine will not be affected by water accumulation and safety production. This principle is designed to ensure the independence and reliability of the underground drainage system at high water levels.

[0127] On the contrary, when the water level in the underground water tank drops to the lowest level (the third underground water level value), the system will automatically stop the operation of the main drainage pump to prevent the pump from running idle without water and causing equipment loss. This operation is also not affected by other control instructions, ensuring that the pump is safely shut down under low water level conditions and extending the service life of the equipment.

[0128] In some embodiments, the invention further comprises:

[0129] The surface water reservoir is used as the water reserve unit of the system. Its water volume is controlled by valves to ensure the rational allocation of water resources. The system will first direct the water volume of the surface water reservoir to the water source heat pump system for use, providing energy support for heating or cooling in the mine. The water source heat pump can extract heat or cold through the temperature characteristics of the drained water, saving energy and reducing dependence on external energy.

[0130] The water in the reservoir is first introduced into the water source heat pump system through a valve to provide the water required by the heat pump to meet seasonal heating or cooling needs. This priority utilization method can maximize the efficiency of water resources while achieving heating or cooling functions.

[0131] When the water source heat pump system uses water, if there is still excess water in the reservoir, the system will transport this excess water to the ore dressing plant through the bypass pipeline for use in ore dressing production. The design of the bypass pipeline ensures that the water source can fully utilize the remaining water after first meeting the needs of the heat pump, avoiding waste of resources and providing continuous and stable water support for the ore dressing plant.

[0132] In some examples, it also includes:

[0133] In order to further improve the energy efficiency of the mine water supply and drainage system, an improved strategy for the pump working mode was introduced to optimize power consumption and reduce overall energy consumption. By using variable frequency technology under different load demands and pre-pumping strategies during low electricity price periods, the system can dynamically adjust the pump operation mode to ensure stable water supply and drainage while achieving intelligent control of energy consumption.

[0134] During off-peak hours, when electricity prices are low, water is pumped in advance to transfer the drained water in the underground water tank to the surface water tank. This not only reduces electricity costs, but also ensures that the water level in the water tank is sufficient during peak water demand to meet the water demand of production. Through intelligent electricity price monitoring, the system automatically starts the underground drainage pump during off-peak hours and transfers the drained water to the surface water tank in advance to ensure a stable supply of water during peak hours. Since electricity prices are lower during off-peak hours, pumping water in advance can significantly reduce electricity expenses, providing economic benefits for the overall operating cost savings of the mine. The implementation of this strategy is based on the dynamic adjustment of electricity price changes and production plans to ensure the dual realization of water supply needs and cost savings.

[0135] When the mine production demand fluctuates, the energy consumption of the water pump will increase due to the change in demand. In order to adapt to different water needs and improve the working efficiency of the pump, the system introduces variable frequency technology in the working mode of the pump, that is, by adjusting the speed of the pump in real time to control the flow and pressure, so as to achieve on-demand water supply.

[0136] Frequency conversion technology can dynamically adjust the running speed of the water pump according to the real-time demand underground and on the surface. For example, when the water demand is low, the frequency converter can reduce the pump speed, reduce the water flow, and reduce energy consumption; when the water demand increases, the pump speed will automatically increase to ensure sufficient water supply. Through intelligent adjustment of the pump speed, the system can avoid unnecessary energy consumption caused by the operation of traditional pumps at full speed, reduce mechanical losses caused by frequent starts and stops, and extend the service life of the water pump equipment.
