[0001] This invention relates to the field of mine environmental control technology, and in particular to a method for a mine local ventilation and cooling system based on liquid air. Background Technology

[0002] In mining operations, ventilation systems are crucial for ensuring personnel safety and health. Traditionally, mechanical fans have been the primary means of mine ventilation. However, with the development of mining technology, especially in complex environments such as ultra-long-distance tunnels or deep metal mines, the application of mechanical fans has gradually shown its limitations. Existing technologies have significantly improved the storage and transportation efficiency of liquid air by optimizing the design of storage containers and the selection of materials. Although this progress has greatly promoted the application of liquid air in many fields, its application in the field of mine ventilation still faces challenges. Further exploration and innovation are needed in areas such as the efficient and low-loss delivery of liquid air to the working face and how to intelligently adjust the release mode based on real-time environmental data.

[0003] Although existing technologies have made significant progress in the storage and transportation of liquid air, they have not fully considered the high demand for fresh air, high concentration of harmful gases, and strict temperature control requirements of the special environment of mines. Especially during ultra-long-distance tunneling, insufficient oxygen supply, accumulation of harmful gases, and high temperature problems caused by insufficient air volume are particularly prominent. This not only affects work efficiency but also poses a potential threat to the health of miners. Traditional ventilation methods are difficult to monitor and control in real time and cannot effectively cope with the dynamic changes in environmental parameters inside the mine. Summary of the Invention

[0004] In view of the aforementioned existing problems, the present invention is proposed.

[0005] Therefore, the present invention provides a mine local ventilation and cooling system based on liquid air to solve the problems of insufficient oxygen supply, accumulation of harmful gases and poor temperature control caused by insufficient air volume in traditional ventilation methods during ultra-long-distance tunneling.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] In a first aspect, the present invention provides a mine local ventilation and cooling system based on liquid air, which includes an intelligent conveying pipeline, an intelligent multi-mode release device, an air purification and energy recovery device, and a mine environment adaptive monitoring and control system.

[0020] Secondly, this invention provides a method for local ventilation and cooling in mines based on liquid air. A smart control module transports liquid air from a storage point to the tunneling face in a low-loss manner. An intelligent multi-mode release device installed at the tunneling face releases the air based on monitored data of oxygen concentration, harmful gas concentration, temperature, humidity, and dust concentration. The released air is then processed by an air purification and energy recovery device. A mine environment adaptive monitoring and control system monitors oxygen concentration, harmful gas concentration, temperature, humidity, and dust concentration in real time, and uses artificial intelligence algorithms to predict environmental change trends.

[0023] As a method for local ventilation and cooling in mines based on liquid air as described in this invention, the mine environment adaptive monitoring and control system optimizes the supply time and strategy of liquid air according to the mine work shifts and personnel distribution.

[0024] As part of the liquid air-based mine local ventilation and cooling method of the present invention, the intelligent monitoring and control system automatically activates the safety valve and pressure relief device and issues an alarm when an abnormal situation is detected.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Reference Figure 1 Figure 2 This is one embodiment of the present invention, which provides a mine local ventilation and cooling system based on liquid air, comprising the following steps:

[0033] The inner wall of the intelligent delivery pipeline is coated with a nano-insulating material to reduce the evaporation loss of liquid air during the delivery process.

[0034] Furthermore, the inner wall of the intelligent conveying pipeline is coated with a nano-insulating material to reduce evaporation loss of liquid air during the conveying process. By applying the nano-insulating material coating to the inner wall of the intelligent conveying pipeline during the liquid air conveying process, the influence of the external environment on the internal temperature of the pipeline can be effectively reduced, thereby reducing evaporation loss of liquid air due to temperature rise. This ensures that the liquid air maintains a low temperature throughout the entire conveying path from the storage point to the tunneling face, maintaining its liquid state and avoiding resource waste caused by unnecessary evaporation. The application of the nano-insulating material coating enhances the thermal insulation performance of the pipeline, enabling liquid air to be conveyed to the target location in a highly efficient and low-loss state, providing a stable material basis for subsequent multi-mode release. This treatment method also indirectly supports the mine's local ventilation and cooling system to achieve more precise and efficient air supply and temperature regulation functions.

[0035] Plasma vaporization heats and rapidly vaporizes liquid air by generating a plasma field, thereby improving the efficiency of the conversion from liquid to gas.

[0036] Furthermore, plasma vaporization heats and rapidly vaporizes liquid air by generating a plasma field, thereby improving the conversion efficiency from liquid to gas. The intelligent multi-mode release device utilizes a plasma generator to produce a plasma field, which rapidly increases the local temperature, causing the liquid air to quickly transform into a gas. This process not only accelerates the vaporization of liquid air but also improves conversion efficiency, ensuring that fresh air can be rapidly and evenly distributed to the mine working face. In this way, sufficient fresh air can be provided to miners in a short time, effectively reducing the temperature of the working environment, improving air quality, and protecting the health and safety of miners. The combination of vaporization and intelligent conveying pipelines with nano-insulating material coatings further reduces evaporation loss of liquid air during transportation, thus ensuring the high efficiency and stability of the entire process.

[0037] Ultrasonic nano-atomization uses ultrasonic energy to break down liquid air into extremely fine particles, forming a mist state, which is used to improve vaporization speed and uniformity.

[0038] Furthermore, ultrasonic nano-atomization utilizes ultrasonic energy to decompose liquid air into extremely fine particles, forming a mist-like state. This improves vaporization speed and uniformity. The ultrasonic nano-atomization function in the intelligent multi-mode release device generates high-frequency vibrations through an ultrasonic generator, causing liquid air to be decomposed into tiny particles as it passes through the device, forming a mist-like distribution. This increases the contact area between the liquid air and the surrounding environment, thereby accelerating its transformation from a liquid to a gaseous state and making the air distribution more uniform. In this way, not only is the efficiency of fresh air supply improved, but it also ensures that all areas of the working face receive a uniform supply of fresh air, effectively improving the air quality in the mine and protecting the safety and health of the workers. The application of ultrasonic nano-atomization combined with plasma vaporization can further optimize the air distribution effect, ensuring that the entire ventilation and cooling process is more efficient and stable.

[0039] The low-temperature plasma purification module uses low-temperature plasma technology to destroy the molecular structure of harmful gases, effectively removing harmful gases such as methane and carbon monoxide.

[0040] Furthermore, the low-temperature plasma purification module utilizes low-temperature plasma technology to disrupt the molecular structure of harmful gases, effectively removing methane, carbon monoxide, and other harmful gases. During operation, the module generates a low-temperature plasma field, causing harmful gas molecules to be bombarded and excited by high-energy electrons, leading to the breakage of their chemical bonds and their transformation into harmless or low-toxic substances. Methane and carbon monoxide molecules undergo decomposition reactions under the influence of the low-temperature plasma, producing safer byproducts such as carbon dioxide and water. This process not only efficiently removes harmful gases from the mine but also avoids the secondary pollution problems that may arise from traditional purification methods. The low-temperature plasma purification module ensures the safety of air quality within the mine, providing a healthier environment for workers. In addition, this purification method, combined with ultrasonic nano-atomization, further optimizes air distribution, ensuring a more efficient and stable ventilation and cooling process, and contributing to improved overall mine safety.

[0041] The dust filtration module uses a high-efficiency electrostatic precipitator and a HEPA filter to capture dust and particles in the air and purify the air quality.

[0042] Furthermore, the dust filtration module captures airborne dust and particles through a high-efficiency electrostatic precipitator and a HEPA filter to purify the air. During operation, air containing dust and particles first passes through the high-efficiency electrostatic precipitator, where electrostatic forces charge the particles and attract them to the collection plates, achieving initial filtration. The air then continues through the HEPA filter, which captures even finer particles, including those with a diameter of 0.3 micrometers or larger, ensuring deep purification. Coal dust and other mineral dust generated during mining operations are effectively removed after these two steps, significantly reducing the content of suspended particulate matter in the air. This not only improves air quality in the mine but also reduces the risk of respiratory diseases for miners. The combination of the dust filtration module and the low-temperature plasma purification module further enhances the overall air purification effect, ensuring a cleaner and safer mining environment and protecting the health of workers.

[0043] The cold energy recovery module is used to recover the cold energy generated during the vaporization of liquid air.

[0044] Furthermore, the cold energy recovery module is used to recover the cold energy generated during the vaporization of liquid air. During operation, when liquid air is vaporized through an intelligent multi-mode release device, the cold energy recovery module captures and stores the cold energy released during this process.

[0045] Specifically, the low-temperature environment generated during vaporization is used to cool other media or stored directly for later use, assisting in localized cooling within the mine or cooling other equipment. Cold energy recovery not only improves energy efficiency but also reduces reliance on external refrigeration equipment, thereby lowering overall energy consumption and operating costs. The cold energy recovery module ensures the effective utilization of cold energy generated during liquid air vaporization, further enhancing the effectiveness of mine environmental control and supporting more energy-efficient and environmentally friendly mine ventilation and cooling. The combination of the cold energy recovery module and the dust filtration module optimizes the energy efficiency of the entire process, ensuring an efficient and coordinated operational chain between each processing step, jointly improving the safety and comfort of mine operations.

[0046] The condensate collection module is used to treat and utilize the condensate generated during the vaporization process.

[0047] Furthermore, the condensate collection module is used to treat and utilize the condensate generated during the vaporization process. During operation, when liquid air vaporizes through the intelligent multi-mode release device, condensate is generated as a byproduct and captured by the condensate collection module. The condensate first undergoes preliminary filtration to remove any potential impurities, and then is stored or used directly for various applications within the mine, such as dust suppression, equipment cooling, or fire suppression. The collected condensate can be used to reduce dust concentration within the mine, improve air quality, or provide a water source for equipment requiring cooling, reducing reliance on external water supply systems. This approach not only achieves efficient resource reuse but also reduces mine operating costs and helps improve overall environmental management efficiency. The combination of the condensate collection module and the cold energy recovery module further optimizes the comprehensive utilization of energy and water resources, ensuring a more environmentally friendly and efficient process, and jointly providing a safer and healthier working environment for the mine.

[0048] The mine environment adaptive monitoring and control system uses artificial intelligence algorithms to analyze and predict the changing trends of environmental parameters in real time.

[0049] Furthermore, the mine environment adaptive monitoring and control system uses artificial intelligence algorithms to analyze and predict the changing trends of environmental parameters in real time. Data collected by sensors for oxygen concentration, harmful gas concentration, temperature, humidity, and dust concentration are transmitted to the central processing unit. The artificial intelligence algorithm performs in-depth analysis of the data to identify patterns and predict future trends. By learning from historical data, the artificial intelligence algorithm can predict in advance whether oxygen concentration may decrease or harmful gas concentration may increase in a certain area, and automatically adjust the delivery and release patterns of liquid air accordingly to ensure that environmental parameters are always kept within a safe range. The real-time monitoring and prediction capabilities not only improve the response speed and accuracy of mine environmental management, but also enable preventive measures to be taken before potential hazards occur, thereby protecting the safety and health of workers. Combined with the application of a condensate collection module, the mine environment adaptive monitoring and control system can further optimize resource utilization and ensure that an efficient and coordinated operation chain is formed between various processing steps, jointly improving the safety and comfort of mine operations.

[0050] This embodiment also provides a method for local ventilation and cooling in mines based on liquid air. The method uses an intelligent control module to transport liquid air from the storage point to the tunneling face in a low-loss manner. An intelligent multi-mode release device installed at the tunneling face releases the air based on data such as oxygen concentration, harmful gas concentration, temperature, humidity, and dust concentration. The released air is then processed by an air purification and energy recovery device. The mine environment adaptive monitoring and control system monitors oxygen concentration, harmful gas concentration, temperature, humidity, and dust concentration in real time and uses artificial intelligence algorithms to predict environmental change trends.

[0051] The intelligent release device with vortex enhancement function generates vortices through the nozzle structure, which effectively diffuses cold air and is used to adjust the direction and speed of airflow.

[0052] Furthermore, the intelligent release device with vortex enhancement function generates vortices through a nozzle structure, effectively diffusing cold air and adjusting the direction and speed of airflow. During operation, the intelligent multi-mode release device utilizes a specially designed nozzle structure to generate vortices after liquid air undergoes plasma vaporization or ultrasonic nano-atomization. These vortices guide the cold air to diffuse evenly within the mine working face, ensuring that cold air covers every corner. By adjusting the nozzle angle and outlet size, the direction and speed of airflow can be precisely controlled, allowing fresh air to be delivered to specific areas as needed. This results in a more uniform temperature distribution and improved air quality, not only increasing local ventilation efficiency but also enhancing cooling effects, providing miners with a more comfortable working environment. Combined with the application of a condensate collection module, the vortex enhancement function further optimizes the airflow path, ensuring a more efficient and coordinated process, jointly improving the safety and comfort of mine operations.

[0053] By using the work schedule and real-time personnel positioning equipment, we can obtain information on mine shifts and personnel distribution.

[0054] Furthermore, by employing planned work schedules and real-time personnel positioning equipment, the mine's work shifts and personnel distribution are obtained. During operation, the pre-established work plan clarifies the tasks and schedules for each shift, while real-time personnel positioning equipment tracks and records the miners' specific locations. Utilizing technologies such as Radio Frequency Identification (RFID), Global Positioning System (GPS), or Bluetooth positioning devices, the movement of each miner within the mine can be accurately monitored. This information is centrally collected and analyzed to determine the personnel distribution at each working face. The mine environment adaptive monitoring and control system can optimize the timing and strategy of liquid air supply based on the actual personnel distribution, ensuring energy savings while maintaining air quality.

[0055] The mine environment adaptive monitoring and control system optimizes the supply time and strategy of liquid air based on mine work shifts and personnel distribution.

[0056] Furthermore, the mine environment adaptive monitoring and control system optimizes the supply time and strategy of liquid air based on mine work shifts and personnel distribution. Information on mine work shifts and personnel distribution, obtained through pre-arranged work plans and real-time personnel positioning equipment, is transmitted to the central processing unit. The system uses artificial intelligence algorithms to analyze and predict the demand at each working face during different time periods, thereby dynamically adjusting the liquid air supply time and strategy. In high-density work areas or during specific shifts, the supply of liquid air is increased, and the operating mode of the intelligent multi-mode release device is adjusted to meet higher ventilation and cooling demands. In low-density work areas or off-peak hours, the supply is reduced to achieve energy savings. This not only improves resource utilization efficiency but also ensures that the air quality in the mine is always at its best, providing miners with a safer and healthier working environment. Combined with the application of eddy current enhancement functions, the airflow direction and speed can be further optimized to ensure that fresh air can be evenly distributed to every work point.

[0057] When the intelligent monitoring and control system detects an abnormal situation, it automatically activates the safety valve and pressure relief device and issues an alarm.

[0058] Furthermore, the mine's environmental parameters are monitored in real time by sensors for oxygen concentration, harmful gas concentration, temperature, humidity, and dust concentration. Once these parameters exceed the preset safety range, such as when the oxygen concentration is too low or the harmful gas concentration is too high, the intelligent monitoring and control system will immediately trigger a response mechanism.

[0059] Specifically, safety valves and pressure relief devices are automatically activated to rapidly reduce pressure and prevent potentially dangerous situations from worsening. Simultaneously, the alarm system is activated, issuing emergency notifications to miners, prompting them to take necessary protective measures or evacuate the site. This not only enables timely response to emergencies but also maximizes the protection of miners' lives and health. Combined with information on mine shift schedules and personnel distribution, the affected areas can be located more accurately, and emergency response strategies can be optimized to ensure that every miner receives timely and effective protection.

[0060] In summary, this invention, through the steps of an intelligent multi-mode release device, achieves efficient conversion and precise distribution of liquid air from storage to the working face. It adjusts airflow speed and direction in real time according to mine environmental parameters, ensuring uniform distribution of fresh air and localized cooling effects, thus improving air quality in the working area and providing miners with a more comfortable working environment. This achieves the beneficial effects of optimizing ventilation efficiency and improving operational safety. The operation of the air purification and energy recovery device, through the effective removal of harmful gases and dust and the recovery and utilization of cold energy and water resources, maximizes resource utilization and achieves environmental protection goals. This step ensures air quality within the mine while reducing energy consumption, further enhancing the system's sustainability and economy.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
