What is a Coal Mine Risk Monitoring and Early Warning System? What s included?

The coal mine risk monitoring and early warning system identifies the unsafe state of various things, the abnormal situation of equipment, and the unsafe factors of the environment. It can realize the identification and alarm of coal stacking, tearing, deviation and overload on the belt, and stop the emergency when necessary to avoid accidents; It can identify potential safety hazards such as smoke and flames on the working face, windwindows and dampers that are not closed, traffic lights on forks that are not lit, and pedestrians driving in inclined alleys.

Broadcast alarms; The intelligent analysis technology is used to realize the intelligent identification of various common violations such as underground personnel not wearing safety helmets, sleeping on duty, playing with mobile phones, smoking, and illegal carrying of people in mine trucks, and realize automatic identification alarms, image capture, video recording and other functions.

In order to strengthen the remote supervision of coal mine safety, promote the coal mining enterprises in our province to further make good use of the "three major systems" of coal mine safety, and improve the ability and level of law enforcement and duty personnel to check and inspect the coal mine safety production risk monitoring and early warning system, on September 24, the Fujian Coal Mine Safety Supervision Bureau organized the overall supervision and law enforcement personnel and duty personnel to carry out the inspection and application training of the coal mine safety production risk monitoring and early warning system.

Comrade Lai Jianjun, an expert in coal mine safety production and a senior engineer of the information support unit of the training and invitation bureau, gave on-site lectures and answers. The training was carried out through the mode of "venue + monitoring practice", and systematic training was carried out for the participants from the aspects of theory, system application and practical operation. The training atmosphere was strong, and in the on-site question answering session, the trainees were enthusiastic to speak and ask questions.

After the lecture, Dai Wenpeng, deputy secretary of the party group, deputy director and first-level inspector of the Fujian Coal Regulatory Bureau, organized the trainees to carry out remote supervision and law enforcement of coal mine safety, spot-checked a coal mining enterprise, found that the personnel went underground and other problems such as overrun, and organized law enforcement personnel to carry out investigation and handling in a timely manner.

Coal mine safety risk monitoring and early warning system mainly includes:

1.Safety monitoring system: methane, carbon monoxide, wind speed, dust, temperature and other sensor settings, overrun alarm value setting, methane, carbon monoxide and other concentration curves, abnormal alarms, coal mine emergency response to early warning information (cause analysis, lifting), etc.

2.Personnel location monitoring system: the number of people going down, the mine leader leading the team to go down the mine, etc., whether the quota is exceeded and other abnormal conditions; Coal mines' emergency response to early warning information (cause analysis, lifting) and other situations.

3.Mine earthquake and in-situ stress monitoring system: mine earthquake, in-situ stress, energy, overrun alarm, analysis of whether there is abnormal situation; Coal mines' emergency response to early warning information (cause analysis, lifting) and other situations.

4.Hydrological monitoring system: early warning information such as coal mine drainage, water level, water temperature, etc., and emergency response (cause analysis and lifting) of early warning information in coal mines.

5.Mining equipment management system: important equipment safety signs, testing and inspection, annual maintenance plan, equipment operation status, etc., and emergency response (cause analysis and release) of early warning information in coal mines.

6.Dual prevention management system: risk identification, risk management and control, hidden danger investigation and management, daily upload of data information, emergency response (cause analysis and lifting) of early warning information in coal mines, etc.

7.Industrial monitoring system: system operation, camera nodes, image transmission, etc., check for violations such as blocking cameras, adjusting the position or angle of cameras without authorization, and stopping production and construction of coal mines.

Characteristics of monitoring and early warning system: Modular design: According to the different business needs of users, the corresponding functional modules can be generated.

Parametric design: The system can not only monitor safety-related data such as gas, wind speed, start-stop, power outage, power feed, etc. It can also monitor various analog quantities, switching quantities, control quantities, adjustment quantities, gauge quantities and cumulative quantities in the underground in real time.

Multi-polar permission management: Set corresponding permissions according to the different responsibilities of provinces, cities, counties, mines, and system administrators.

Data processing: centralized data storage, various forms of data backup, log backup of important data, support dynamic compression storage, and regular processing. The disconnected data is retransmitted.

Data display: lists, curves, reports, etc.

Data interface: Adopt a unified and standardized data communication protocol, and the network connection follows the principle that the subordinate user obeys the superior user and the superior user provides the data format and transmission technology. Real-time data transmission.

Based on the open-source Web GIS, a supervision map is built, which displays the status information of each mine in layers and categories, and views the detailed real-time data of each mine.

The system stores the spatial information of the graphics in the form of points, lines and surfaces of the graphic elements, so that the graphics can be arbitrarily enlarged, reduced, roamed and printed out at any scale without distortion, and can intuitively carry out information query and various spatial analysis and decision support on the map. Real-time monitoring data for working condition information such as ventilation system, fan, damper status and monitoring system can be prominently displayed at the actual location of the mining engineering drawing; For all kinds of inspector information, it can be directly marked on various operation points, and the rectification situation can be seen at a glance.

Easy to operate and low maintenance of the system.

The system uses a browser page to replace the usual complicated professional application operation interface, making the operation interface extremely simple and easy to use, and the user does not need to install the application software system, which greatly reduces the maintenance cost of the system.

Convenient network monitoring capabilities.

After obtaining security authentication and permission, the system can be accessed at any node of the network to achieve real-time monitoring, network supervision and information query.

1.The alarm accuracy is high.

2.Real-time identification of alarms.

Based on intelligent analysis and deep learning neural network technology, real-time identification and early warning of personnel intrusion in the dangerous monitoring area, the alarm information can be displayed in the monitoring client interface, and the alarm information can also be pushed to the mobile terminal.

3.All-weather operation, stable and reliable.

4.Alarm storage function.

Promote the construction of safety production risk monitoring and early warning systems. Implement the "Industrial Internet + Safe Production" action plan, add the most advanced intelligent analysis function, and realize the intelligent identification of risks and hidden dangers such as violations and abnormal situations. At the same time, integrate the supervision and law enforcement system of key industries and fields of mines, and form a unified national emergency management supervision and law enforcement information system and database.

Speed up the monitoring network of underground mines, tailings ponds, and metal and non-metal open-pit mines with slope heights of more than 200 meters.

The coal mine safety risk monitoring and early warning system is mainly based on remote real-time monitoring and monitoring of coal mine safety, and integrates the functions of safety information collection, dynamic tracking of mining location, hidden danger warning, accident alarm, safety supervision, safety scheduling, etc., and can integrate the existing safety production monitoring and monitoring system and new system in different periods, different types and different technologies on a unified platform.

The coal mine safety risk monitoring and early warning system mainly includes three systems, and the three major systems refer to:

Hello dear! The three major systems of coal mines refer to power supply, ventilation, and transportation. 1. Power supply:

The electric energy will be sold safely, reliably, continuously and qualified to the majority of power customers through the transmission and distribution devices, so as to meet the needs of the customers for economic construction and living electricity. The power supply institutions include the power supply bureau and the power supply company. 2. Ventilation:

The use of natural or mechanical methods to make the wind unobstructed, can be transported through the room, into the room or sealed environment, to create a hygienic, safe and other suitable air environment technology quiet. Constant ventilation can improve indoor air quality and is good for health. 3. Transportation:

The act of transporting the subject (person or goods) moving from place A to place B through the means of transport (or means of transport and transport routes) to complete a certain economic purpose.
