Description

Technical Field

[0001] The invention relates to the technical field of mine command systems, in particular to a mine emergency rescue command system. Background Art

[0002] Mining is a high-risk industry, especially in underground operations such as coal mines and metal mines, where miners face many deadly dangers such as mine collapse, gas explosion, coal dust explosion, and water seepage accidents. According to statistics, mining accidents have a higher mortality rate among all types of industrial accidents in the world. In order to reduce casualties and economic losses caused by mining accidents, mine safety has always been the focus of attention of governments and enterprises in various countries. Although modern mines have adopted some advanced safety technologies and equipment, the complex environment of mining operations and the suddenness of accidents still pose huge challenges to emergency rescue.

[0003] The existing mine emergency rescue technical means mainly include the following categories:

[0004] Manual monitoring and manual command: Traditional mine rescue often relies on manual monitoring, and the commander manually dispatches and commands based on historical experience and on-site conditions in mine operations. This method is easily affected by subjective judgment, and it is difficult to obtain real-time data from the mine in a timely and accurate manner when an accident occurs, resulting in a slow emergency response and unscientific decision-making.

[0005] Environmental monitoring equipment is single and scattered: The operating environment of mines is complex and changeable. Existing safety monitoring equipment often focuses on the collection of single environmental parameters, such as gas detection or temperature and humidity monitoring, and lacks comprehensive data collection capabilities. Moreover, these devices usually work independently, and the data cannot be effectively integrated, resulting in the command center being unable to obtain the overall status of the mine.

[0006] Data transmission delay and poor communication: Since mines are located underground and the communication environment is poor, traditional wired communication methods are difficult to deploy widely in mines, and wireless communication methods are easily affected by geological conditions underground, resulting in data transmission delays or interruptions, further affecting the timeliness and effectiveness of emergency command and dispatch.

[0007] Lack of intelligent analysis and decision-making support systems: Existing systems mostly rely on manual analysis of monitoring data and cannot automatically identify accident risks. Environmental data in mines is complex and diverse, and has the characteristics of real-time changes. If it only relies on manual processing, it is impossible to respond quickly and accurately judge risks, and the best rescue opportunity will often be missed.

[0008] Emergency rescue command lacks unity and coordination: In large-scale accidents, rescue operations usually involve multiple teams and different rescue departments. The traditional command model easily leads to inconsistent command and dispatch, unreasonable allocation of rescue resources, and even puts rescue personnel in dangerous situations during operations, resulting in poor rescue results.

[0009] In view of the limitations of the above existing technologies, there is an urgent need for an emergency rescue command system that can conduct comprehensive and real-time monitoring of the mine operating environment, intelligently analyze environmental data, quickly issue warnings, and uniformly dispatch rescue forces.

[0010] The development of modern technologies, such as the Internet of Things, cloud computing, wireless communications, big data analysis, and artificial intelligence, has provided new opportunities for upgrading mine emergency rescue systems. These technologies can improve the speed of emergency response and the accuracy of command by collecting underground environmental parameters in real time, automatically identifying risks, and intelligently generating rescue plans.

[0011] In summary, the existing mine emergency rescue technology has many deficiencies. Mine rescue requires a more efficient and intelligent emergency command system that can combine real-time mine environment information, personnel positioning and dynamic rescue plans to cope with the suddenness, complexity and high risk of accidents and minimize the losses and harm caused by mine accidents. This provides an important technical background and demand basis for the mine emergency rescue command system proposed in this invention.

BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Figure 1 This is a structural block diagram of a mine emergency rescue command system proposed by the present invention. DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The following is combined with Figure 1 With reference to the accompanying drawings and a number of embodiments, specific embodiments of the present invention are described in detail.

[0050] Example 1: Mine environment data collection and analysis

[0051] In the daily production process of a coal mine, a mine emergency rescue command system of the present invention is installed. First, the mine environment data acquisition module deploys multiple sensor nodes in the mine, including gas sensors, temperature sensors, humidity sensors, dust sensors and personnel positioning equipment. The specific layout is as follows:

[0052] Gas sensors: Multiple gas sensors are placed in different tunnels and working faces of coal mines to monitor the concentration of methane and ensure that the risk of gas leakage is captured in real time.

[0053] Temperature and humidity sensors: Installed in the main working area and bottom of the mine, used to measure temperature and humidity changes in the mine to ensure that the environment is suitable for mining operations.

[0054] Dust sensor: Deployed in dust-prone areas such as crushing and loading and unloading in coal mines to monitor dust concentration in the air in real time to prevent excessive dust concentration from causing explosions or affecting breathing safety.

[0055] Personnel positioning equipment: Radio frequency identification (RFID) equipment is installed on the helmets or belts worn by miners to collect the location information of all personnel in the mine in real time to ensure the safe positioning and dispatch of personnel.

[0056] The data collected by the above sensors in real time are uploaded to the ground command center through the wireless transmission module. After the data processing module of the ground command center receives the data, it uses the following comprehensive safety assessment formula for real-time analysis:

[0057] S=α1·G CH4 +α2·T+α3·H+α4·D+α5·P

[0058] Among them, S is the comprehensive safety score of the mine environment, G CH4 is the gas concentration, T is the temperature, H is the humidity, D is the dust concentration, P is the personnel distribution density, α1, α2, α3, α4, α5 are the weight coefficients of different environmental factors, which are set according to historical data and expert experience, reflecting the gathering of miners in the mine; α1, α2, α3, α4, α5: are the weight coefficients of different environmental factors, which are determined by experience and historical data.

[0059] When the comprehensive safety score S is lower than the preset safety threshold S threshold When a warning occurs, the risk warning module automatically triggers a warning and displays the alarm information to the command center, including the location of the dangerous area, the danger level, and related environmental parameters.

[0060] Example 2: Risk warning and command and dispatch

[0061] Based on Example 1, the system finds that the gas concentration of a certain working face gradually increases and exceeds the set threshold. At this time, the risk warning module automatically triggers the alarm, the ground command center immediately receives the alarm signal, and alerts the duty personnel through the sound and light alarm device.

[0062] The command and dispatch module is activated, and the on-duty commander checks the real-time monitoring screen through the system interface and determines the location of the gas leak based on the historical data trend of the gas sensor. Based on the real-time location information of the miners, the commander quickly dispatches the rescue team to a safe area and issues an evacuation order to the workers in the mine.

[0063] The command and dispatch module keeps in touch with the personnel in the mine through the voice communication system, confirms the evacuation situation, and monitors the movement progress of the rescue personnel. The system combines the three-dimensional map of the mine and the personnel positioning data to provide the optimal evacuation path and rescue route.

[0064] Example 3: Rescue route planning and decision support

[0065] Based on Example 2, a gas explosion occurred inside the mine, causing part of the tunnel to collapse and trapping some miners underground. At this time, the rescue assistance module is activated, and the system automatically generates possible rescue plans based on the three-dimensional map of the mine and the real-time location information of the miners, and provides the optimal rescue path planning.

[0066] The calculation formula for rescue path planning is:

[0067]

[0068] Among them, L optimal is the total distance of the optimal rescue path, d i is the path length from the command center to the i-th rescue point, and n is the number of rescue points.

[0069] The system will convey the planned optimal route to the on-site rescue team through the command and dispatch module, and update the rescue path in real time to ensure the safety and efficiency of the rescue operation.

[0070] Example 4: Emergency protection in case of power outage

[0071] In order to ensure the normal operation of the system under extreme circumstances, the system of the present invention is also equipped with a power guarantee module. A serious accident occurred in a mine, resulting in a complete interruption of the underground power system and some equipment in the command center could not operate normally. At this time, the power guarantee module automatically switched to the backup power supply to ensure that the command system continued to operate normally.

[0072] The power guarantee module is equipped with a backup battery pack to keep the system running in the absence of power, and a solar power generation system is installed as a backup power source for long-term rescue operations. Through these power guarantee measures, the system can continue to provide emergency rescue command services in complex and extreme environments.

[0073] Example 5: Historical data analysis and rescue optimization

[0074] In another embodiment of the present invention, the system integrates cloud platform storage and data mining functions. During the mine operation, all sensor data, warning events, and rescue command and dispatch history will be automatically uploaded to the cloud for subsequent analysis and learning.

[0075] The system uses machine learning algorithms to analyze historical rescue data and optimize rescue plans. For example, by analyzing previous gas leaks and rescue success rates, the system can adjust weight coefficients α1, α2, α3, α4, and α5 to improve the accuracy of predicting dangerous situations. At the same time, the rescue assistance module can optimize future rescue path planning based on historical data, making each rescue operation faster and more efficient.

[0076] This data-driven optimization process enables the mine emergency rescue system to continuously learn and improve during application, enhancing the intelligence level of mine rescue and reducing accident losses.

[0077] Example 6: Unified emergency command in multiple mining areas

[0078] The system of the present invention can also be applied to the centralized monitoring and unified command of multiple mines. In multiple mining areas under a company, the emergency rescue systems of each mine can be connected to the general command center through a cloud platform. The general command center can monitor the production and safety of all mines in real time. When an emergency occurs in any mine, the system can mobilize rescue forces inside and outside the company through a unified command platform to achieve cross-mine and cross-department emergency coordinated command.

[0079] For example, when a serious gas leakage accident occurred in a mining area, the general command center immediately linked up with the rescue forces of other mines through the system, dispatched technical experts and rescue equipment to the scene, and maximized the response efficiency of emergency rescue.

[0080] The mine emergency rescue command system of the present invention greatly improves the efficiency and accuracy of mine emergency rescue through the integration of multifunctional modules such as data collection, wireless transmission, data analysis, command and dispatch, and rescue assistance. The system has the characteristics of real-time, intelligent, information integration, and remote command, ensuring rapid response and effective command when a mine accident occurs, reducing casualties and property losses. The diversified implementation methods of the system are suitable for mine operation scenarios of different types and sizes, and have broad application prospects.
