Description

Technical Field

[0001] This invention relates to the field of underground safety equipment technology, specifically to a safety device based on mine ventilation network simulation control and its usage method. Background Technology

[0002] Mine ventilation systems are the lifeline for ensuring safe production in mines. For complex ventilation networks with multiple shafts and roadways, effective management and control are crucial. However, existing mine ventilation systems and their control methods still have the following significant shortcomings, hindering further improvements in ventilation safety and efficiency:

[0003] First, the data acquisition capability is insufficient and the sensing accuracy is low: the existing system mainly relies on a small number of fixed sensors for data acquisition, with limited and immobile deployment points. This results in blind spots in the collected information such as tunnel air volume, node air pressure, temperature, and humidity, failing to comprehensively and accurately reflect the true operating status of the entire complex ventilation network. Consequently, subsequent analysis and decision-making are based on incomplete and inaccurate data.

[0004] Secondly, the control relies on manual operation, resulting in a slow response time: Adjustments to the ventilation network, such as airflow distribution and fan operating conditions, largely depend on manual operation by technicians based on experience. This method not only makes it difficult to guarantee control precision but also results in a long cycle from problem detection to control implementation, leading to a slow response time. This cannot meet the demand for rapid response to dynamic changes in mine production, posing safety hazards.

[0005] Third, equipment maintenance is difficult and fault handling efficiency is low: when a specific section of the ventilation duct network malfunctions or equipment needs maintenance, existing technologies struggle to quickly and accurately locate the problem. Furthermore, faulty equipment is typically installed at the top of the mine, requiring dangerous work at heights for repairs. This not only increases the risk to workers but also makes maintenance time-consuming and labor-intensive, severely impacting the continuous and stable operation of the ventilation system.

[0006] Therefore, there is an urgent need in this field for a comprehensive ventilation safety device and method that can achieve full and accurate perception, rapid and intelligent control, and convenient and safe equipment maintenance to overcome the above-mentioned shortcomings. Summary of the Invention

[0007] To address the aforementioned problems, and especially the shortcomings of existing technologies, this invention provides a safety device and its usage method based on mine ventilation network simulation control, which can solve the problems of low data acquisition accuracy and low equipment maintenance efficiency.

[0014] Optionally, a data acquisition and communication module is fixedly installed on the conveyor belt. The data acquisition and communication module is provided with an acquisition base on its upper part. Fixed plates are provided on both sides of the acquisition base. An acquisition hydraulic pump is provided at the bottom of the acquisition base. Three hydraulic lifting shafts are provided at the bottom of the acquisition hydraulic pump.

[0018] Optionally, the dust removal module includes a pipe body, a set of fixing modules is installed in the pipe body, a rotating rail is provided on the outside of the pipe body, and three sets of dust removal plates are slidably connected in the rotating rail.

[0019] Secondly, the present invention provides a method for using the safety device based on mine ventilation network simulation control as described in the first aspect, comprising the following steps:

[0020] S1. Form a ventilation network: Based on the mine layout design, arrange frames, control ducts and transmission modules at various locations in the mine to form a mine ventilation network.

[0021] S2. Fixed ventilation network: The frame and control air duct are fixed to the top of the mine through the fixed module, and the transmission module is fixed to the top of the mine through the fixed seat on the top of the transmission module.

[0022] S3. Construct a digital twin model of mine ventilation. First, the staff inputs the spatial data of the underground roadway into the controller service base station. Then, through the horizontal sliding and vertical extension of the data acquisition and communication module, the air volume, node air pressure, temperature and humidity information of the entire space are obtained to the maximum extent. Construct and render a three-dimensional digital twin model of the mine ventilation network. Dynamic simulation of ventilation conditions is carried out in the digital twin model.

[0023] S4. Analyze and control the ventilation network. The controller service base station includes a ventilation network analysis module based on a digital twin model. It calculates and analyzes the network topology and pressure distribution of the digital twin model, integrates the analysis structure, and adjusts the fan modules in each first section of the duct to optimize the ventilation network.

[0024] S5. Dust Collection and Maintenance: During ventilation, the dust removal module in the control duct collects and removes dust from the air in real time, purifying the underground environment. At the same time, the wind speed detector monitors the wind speed in the control duct in real time. When the wind speed is much lower than the wind speed generated by the fan module controlled by the controller service base station, it indicates that the control duct is blocked. At this time, the corresponding alarm will sound and its corresponding fixed module will be activated. The lifting frame will automatically lower the abnormal section in the control duct to the bottom for easy maintenance by the operators.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. Achieves comprehensive, accurate, and dynamic perception of the entire ventilation network: This invention, through a data acquisition and communication module that can slide laterally and extend vertically, breaks through the limitations of traditional fixed sensor deployment, enabling the acquisition of multi-dimensional ventilation parameters within the mine space over the largest possible area. This provides a reliable data foundation for constructing a high-precision digital twin model of mine ventilation, fundamentally solving the problems of single data acquisition and low accuracy.

[0027] 2. Achieves rapid, automatic, and intelligent control of the ventilation system: This invention, through an integrated controller service base station and ventilation network analysis module, can analyze the network status in real time based on a digital twin model and automatically generate optimized control strategies to directly control the fan module for frequency conversion adjustment. This process represents a leap from "human experience-based judgment" to "system intelligent decision-making," with fast response speed, high control accuracy, and effectively ensures that the ventilation system dynamically adapts to production changes.

[0028] 3. Significantly improves the safety and convenience of equipment maintenance: Addressing the challenges of equipment fault location and maintenance, this invention features an intelligent diagnostic and automatic descent maintenance mechanism. Through the linkage of a wind speed detector and an alarm, abnormal sections can be quickly located. Most importantly, by activating the corresponding fixing module, the lifting frame automatically lowers the blocked or malfunctioning control duct section to the ground. This innovative design completely avoids high-risk work at height, enabling maintenance to be carried out safely and conveniently on the ground, greatly improving maintenance efficiency and operational safety.

[0029] 4. A complete technical solution integrating sensing, simulation, control, and maintenance has been constructed: This invention deeply couples hardware devices (framework, air duct, transmission module, fixing module, dust removal module, etc.) with software systems (digital twin model, analysis and control algorithms) to form a complete closed-loop system. It not only solves the ventilation optimization problem but also purifies the underground environment through the dust removal module and solves the long-standing equipment maintenance problem in the industry through its unique mechanical structure, achieving a systematic improvement in ventilation safety assurance capabilities.

Detailed Implementation

[0048] The present invention will be further described below with reference to the accompanying drawings. Example 1:

[0049] As attached Figures 1 to 9 As shown, in one embodiment of the present invention, a safety device based on mine ventilation network simulation control includes a frame 2. Two sets of control air ducts 3 are installed on the side of the frame 2. Two transmission modules 4 are arranged between the two sets of control air ducts 3. A sliding and lifting data acquisition and communication module 5 is sandwiched between the two transmission modules 4. A fixing module 6 is installed on the upper part of the frame 2 and the control air ducts 3. The control air ducts 3 are divided into three sections, and a dust removal module 7 is installed in each section. A wind speed detector 8 is arranged at the rear of the dust removal module 7. An alarm 9 is connected to the bottom of the wind speed detector 8. The fixing module 6 includes a lifting frame 62, which is used to automatically lower the corresponding section to the bottom when an abnormality occurs in a certain section of the control air duct 3.

[0050] Specifically, during ventilation, the three sets of dust removal plates 73 in the dust removal module 7 of the control air duct 3 rotate along the rotating rail 72 to collect and remove dust from the passing air in real time, purifying the underground environment. At the same time, the wind speed detector 8 monitors the wind speed of the control air duct 3 in real time. When the wind speed is much lower than the wind speed generated by the fan module 311 controlled by the controller service base station 23, it indicates that the control air duct 3 is blocked. At this time, the corresponding alarm 9 sounds an alarm, and the controller service base station 23 automatically controls the corresponding fixed module 6 to start, and the lifting frame 62 opens to the maximum, automatically lowering the abnormal section in the control air duct 3 to the bottom for easy maintenance by the operators.

[0051] As attached Figures 1 to 6 and Figure 16 As shown, the data acquisition and communication module 5 is connected to the sensor network installed inside it and is configured to acquire and preprocess the dynamic parameters of the mine ventilation system in real time. The sensor network includes a wireless pressure sensor 55, a wireless wind speed sensor 56, and a wireless temperature sensor 57. A hydraulic lifting shaft 53 is provided at the bottom of the data acquisition and communication module 5, and the sensor network is installed on the hydraulic lifting shaft 53. The data acquisition and communication module 5 can detect the dynamic parameters of the entire space during the movement of the hydraulic lifting shaft 53 and transmit the dynamic parameters to the controller service base station 23 installed inside the main air duct 21. The dynamic parameters include roadway air volume, node air pressure, and temperature and humidity data.

[0052] Furthermore, the data acquisition and communication module 5 is activated at regular intervals. The hydraulic pump 52 starts and opens all three hydraulic lifting shafts 53. The wireless pressure sensor 55, wireless wind speed sensor 56, and wireless temperature sensor 57 on one side of each hydraulic lifting shaft 53 start working. Warning light strips 54 installed on the other three sides of the hydraulic lifting shaft 53 flash to warn other personnel to avoid the area. Then, the first drive motor 41 starts and drives the conveyor belt 43 to move at a constant speed. This drives the data acquisition and communication module 5 to start moving. In this way, the lateral sliding of the transmission module 4 and the longitudinal extension of the hydraulic lifting shaft 53 maximize the acquisition of the air volume, node air pressure, temperature and humidity information of the entire space. Example 2:

[0053] As attached Figures 5 to 13 As shown, in one embodiment of the present invention, the safety device based on mine ventilation network simulation and control, based on embodiment 1, includes a main air duct 21 on the frame 2, an air outlet 22 on one side of the main air duct 21, and a controller service base station 23 installed inside the main air duct 21; the control air duct 3 includes a first section air duct 31, a second section air duct 32, and a third section air duct 33, and a fan module 311 is installed inside the first section air duct 31. The fan module 311 includes an adjustable fan frame, a pressure transmitter, and a control module, and the adjustable fan frame, pressure transmitter, and control module realize frequency conversion speed regulation of the fan module 311.

[0054] As attached Figures 8 to 14As shown, a first drive motor 41 is provided at one end of the transmission module 4, and a main shaft 42 is provided at the output end of the first drive motor 41. A transmission belt 43 is sleeved on the upper part of the main shaft 42, and a support frame 44 is provided on the inner side of the transmission belt 43. A fixed seat 45 is provided on the upper part of the support frame 44. An auxiliary shaft 46 is sleeved on the other end of the transmission belt 43. A data acquisition and communication module 5 is fixedly installed on the transmission belt 43. A data acquisition and communication module 51 is provided on the upper part of the data acquisition and communication module 5. Fixed plates 50 are provided on both sides of the data acquisition seat 51. A data acquisition hydraulic pump 52 is provided at the bottom of the data acquisition hydraulic pump 52. Three hydraulic lifting shafts 53 are provided at the bottom of the data acquisition hydraulic pump 52. Three sets of sensors are provided on one side of each hydraulic lifting shaft 53, and warning light strips 54 are installed on the other three sides of the hydraulic lifting shaft 53.

[0055] As attached Figures 9 to 15 As shown, a fixed hydraulic pump 61 is provided at the bottom of the fixed module 6, a lifting frame 62 is provided on the upper part of the fixed hydraulic pump 61, a first base plate 63 is installed on the top of the lifting frame 62, and a second drive motor 64 is installed on the upper part of the first base plate 63; a functional rotating frame 65 is provided at the output end of the second drive motor 64, and a first drill bit 66 is provided on the top of the functional rotating frame 65; a functional hydraulic pump 651 is embedded in each of the two sides of the functional rotating frame 65, a transverse telescopic rod 652 is provided at the output end of the functional hydraulic pump 651, a second base plate 653 is installed at the top of the transverse telescopic rod 652, a third drive motor 654 is installed on the upper part of the second base plate 653, and a second drill bit 655 is provided at the output end of the third drive motor 654.

[0056] As attached Figures 7 to 16 As shown, the dust removal module 7 includes a pipe body 71, a set of fixing modules 6 are installed in the pipe body 71, a rotating rail 72 is provided on the outside of the pipe body 71, and three sets of dust removal plates 73 are slidably connected in the rotating rail 72.

[0057] Furthermore, regarding the working principle of this device, the operators arrange the frame 2, the control air duct 3, and the transmission module 4 at various locations in the mine 1 according to the mine layout design, forming a mine ventilation network. Before installation, the spatial data of the roadway in the lower part of the mine 1 is input into the controller service base station 23.

[0058] During installation, the frame 2 and the control air duct 3 are fixed to the top of the mine 1 by the fixing module 6. Specifically, the fixing hydraulic pump 61 is started, the lifting frame 62 pushes out the first base plate 63, and at the same time the second drive motor 64 is started, driving the first drill bit 66 to drill a hole in the top of the mine 1. After the first base plate 63 contacts the top of the mine, the fixing hydraulic pump 61 and the second drive motor 64 stop working, and the function hydraulic pump 651 and the third drive motor 654 are started, driving the second drill bit 655 to drill forward into the mine 1. In this way, the frame 2 and the control air duct 3 are installed on the top of the mine 1. Then, the transmission module 4 is fixed to the top of the mine 1 by the fixing seat 45 on the top of the transmission module 4.

[0059] During operation, the data acquisition and communication module 5 is activated at regular intervals. The hydraulic pump 52 starts and opens all three hydraulic lifting shafts 53. The wireless pressure sensor 55, wireless wind speed sensor 56, and wireless temperature sensor 57 on one side of each hydraulic lifting shaft 53 start working. Warning light strips 54 installed on the other three sides of the hydraulic lifting shaft 53 flash to warn other personnel to avoid the area. Then, the first drive motor 41 starts and drives the conveyor belt 43 to move at a constant speed. This drives the data acquisition and communication module 5 to start moving. In this way, the lateral sliding of the transmission module 4 and the longitudinal extension of the hydraulic lifting shaft 53 maximize the acquisition of the air volume, node air pressure, temperature and humidity information of the entire space.

[0060] Next, the information is transmitted to the controller service base station 23 for data analysis, and a three-dimensional digital twin model of the mine ventilation network is constructed and rendered. Dynamic simulation of ventilation conditions is performed in the digital twin model. The controller service base station 23 includes a ventilation network analysis module based on the digital twin model, which calculates and analyzes the network topology and pressure distribution of the digital twin model, integrates the analysis structure, and adjusts the fan modules 311 in each first section of the duct 31 to optimize the ventilation network.

[0061] During ventilation, the three sets of dust removal plates 73 in the dust removal module 7 of the control air duct 3 rotate along the rotating rail 72 to collect and remove dust from the passing air in real time, purifying the underground environment. At the same time, the wind speed detector 8 monitors the wind speed of the control air duct 3 in real time. When the wind speed is much lower than the wind speed generated by the fan module 311 controlled by the controller service base station 23, it indicates that the control air duct 3 is blocked. At this time, the corresponding alarm 9 sounds an alarm, and the controller service base station 23 automatically controls the corresponding fixed module 6 to start. The lifting frame 62 opens to the maximum and automatically lowers the abnormal section in the control air duct 3 to the bottom for easy maintenance by the operators. Example 3:

[0062] This embodiment provides a method for using the safety device based on mine ventilation network simulation control as described in Embodiment 1 or Embodiment 2, the steps of which are as follows:

[0063] S1. Form a ventilation network. According to the mine layout design, frame 2, control air duct 3 and transmission module 4 are arranged in various locations of mine 1 to form a mine ventilation network.

[0064] S2. Fix the ventilation network by fixing the frame 2 and the control air duct 3 to the top of the mine 1 through the fixing module 6, and fix the transmission module 4 to the top of the mine 1 through the fixing seat 45 on the top of the transmission module 4.

[0065] S3. Construct a digital twin model of the mine ventilation system. This step is the core data foundation and simulation platform construction stage for realizing the intelligentization of the ventilation system. The specific implementation is as follows:

[0066] First, the staff pre-entered the three-dimensional spatial geographic information of the mine roadway 1 (including cross-sectional dimensions, elevation, length, topological connection relationship, etc.) into the controller service base station 23 to form a network skeleton; then, the data acquisition and communication module 5 was activated to move laterally and extend longitudinally, thereby dynamically covering different positions of the roadway cross-section. Through this "mobile scanning" measurement, the system can maximize and collect real-time and continuous roadway air volume, nodal air pressure and temperature and humidity data, and transmit them back to the controller service base station 23 for analysis.

[0067] The core software of the controller service base station 23 receives and integrates static spatial data and dynamic acquisition data, and uses a 3D graphics engine to construct and render a high-fidelity 3D digital twin model of the mine ventilation network. This model is not only a visual interface, but also has an embedded fluid dynamics solver. Staff or the system can set or modify boundary conditions (such as fan frequency and damper opening) in the model, and the model can perform dynamic simulation of ventilation conditions in the background. Within seconds, it can predict and display the airflow distribution, resistance status and fan operating point of the entire network. The simulation error is controlled within the allowable range of the project, providing advanced and reliable sand table simulation for decision-making.

[0068] S4. This step is the intelligent decision-making and automatic execution stage based on the digital twin model. The specific process is as follows:

[0069] The ventilation network analysis module built into the controller service base station 23 automatically starts to perform in-depth calculations on the physical network carried by the aforementioned digital twin model. It uses graph theory and ventilation network solution theory to analyze the network topology, identify critical paths, corner branches, and weak links. At the same time, it calculates the pressure energy distribution of the entire network and locates abnormal high pressure differential sections and energy consumption bottlenecks. The module integrates the above analysis results (structural characteristics and pressure energy status) and automatically generates control strategies based on preset optimization algorithms (such as aiming for on-demand airflow distribution, minimum total power consumption, and maximum stability). The core output of this strategy is a set of frequency conversion adjustment instructions for each fan module 311 in the first section of the duct 31. The system sends specific frequency adjustment commands to the control modules of the corresponding fan modules 311 through the controller service base station 23.

[0070] Through this closed-loop process, the system achieves real-time analysis, dynamic optimization, and precise control of the ventilation network. It no longer adjusts a single fan in isolation, but performs collaborative optimization based on the status of the entire network, thereby significantly improving ventilation efficiency, stability, and economy.

[0071] S5. Dust collection and maintenance: During ventilation, the dust removal module 7 in the control duct 3 collects and removes dust from the passing air in real time to purify the underground environment. At the same time, the wind speed detector 8 monitors the wind speed in the control duct 3 in real time. When the wind speed is much lower than the wind speed generated by the fan module 311 controlled by the controller service base station 23, it indicates that the control duct 3 is blocked. At this time, the corresponding alarm 9 sounds an alarm, and its corresponding fixed module 6 is activated. The lifting frame 62 automatically lowers the abnormal section in the control duct 3 to the bottom for easy maintenance by the operators.
