The rapid development of the information industry has provided rare development opportunities for the informatization of safe production. The rise of a new round of information technology revolution with the Internet of Things as the core has become a “booster” to solve the industrial and mining safety problems in areas with high incidence of safety accidents. “.
The integration of industrialization and industrialization breaks through the dilemma of safety management
Some experts in the field of coal mines have conducted statistics on the causes of mine disasters in about 30 years since 1980 and found that coal mine accidents caused by “human factors” accounted for more than 90% of all coal mine accidents. Compared with the objective existence of the former, the latter is the key factor that restricts the intrinsic safety of industrial and mining production. How to effectively eliminate the “man-made disaster” factor is a bottleneck problem that needs to be resolved as soon as possible.
According to incomplete statistics, in 2009 and 2010 alone, there were a total of 3,019 coal mine accidents nationwide, with more than 5,000 deaths. In the first three quarters of 2011, the number of deaths from coal mine accidents in my country dropped by 27.6 compared with last year. %, but the total number is still around 1760. Although the total death toll from coal mine accidents has been declining year by year, and a major accident that killed more than 10 people has been effectively controlled, the number of deaths caused by coal mine accidents remains high. In fact, the above data is only for coal mines. If the scope is expanded to the entire industrial and mining industry, the data will be further increased on this basis.
Regarding how to reduce industrial and mining safety production accidents, there have been comments that although the current industrial and mining accidents are accompanied by many subjective and objective factors, on the whole, on the one hand, due to the complex geological conditions of most of the industrial and mining industries in my country, major accidents are easily caused. On the other hand, my country’s safety management technology started relatively late compared with the developed Western mining countries. The current level of informatization in my country’s industrial and mining industry is still low, and it is suitable for underground information technology, The level of electronic information products and industrialization is very backward, unable to meet the needs of industrial and mining safety production, disaster warning, emergency rescue, etc., traditional communication networks are difficult to get down, and underground emergency dispatch and command are difficult to notify people from time to time.
In this situation, in order to break through the dilemma of safety management of industrial and mining enterprises, traditional informatization management methods can no longer meet the needs of industrial and mining enterprises for seamless management, and the real-time and convenient information acquisition and processing that mobile informatization can bring And the natural advantage of passing on makes it possible to truly realize the intrinsic safety management of industrial and mining industries.
In the “12th Five-Year Plan for Work Safety” issued by the state, it is clearly required that through the application of Internet of Things technologies such as electronic tags, fixed-mobile convergence networks, and sensors, innovate production safety supervision and emergency work methods and methods to further strengthen The enterprise implements the supervision and management of the main responsibility of safety production.
Mobile IoT helps safe mines
Li Yue, President of China Mobile, once stated to the media that China Mobile attaches great importance to promoting the application of information technology such as the Internet of Things in safe production. With chemical application, the incidence of various hidden danger accidents has been significantly reduced, and labor efficiency has increased by 22%.
In the No. 3 Mine of Jilin Province, China Mobile’s “Gongmintong” management system has assisted it to carry out networked inspections, dynamic tracking and supervision of major hazards and hidden dangers of safe production, analysis of various possible factors, and systematic prevention and control. , So that the risk factors are always kept in a controllable and safe state. At the same time, China Mobile’s “Gongmintong” management system directly builds the safety production dispatching room of industrial and mining enterprises on the mobile phones of managers, and transmits the data monitored by radio frequency devices, underground environment monitoring devices, gravity sensors, etc. to the management through the mobile network. Personnel’s mobile phone terminal, so as to realize the presentation of various production data on the mobile phone, so that managers can grasp the information of coal mine “production, transportation, sales” and other links in real time, and conveniently seamlessly link multiple systems such as monitoring, communication, and transportation. Became a reality.
Turn on the mobile phone and enter the “Gongmintong” safety information management system. In the seven functional modules of mine personnel positioning, safety data detection, video monitoring, key project management, production daily report, safety warning, and information release, the monitor can not only monitor the mine’s information Information such as production safety, operating data, and company information can be checked. You can also monitor mine gas, carbon monoxide concentration, water immersion, wind speed and other data anytime and anywhere, and you can even clearly see the video images of each monitoring area under the mine. The location of each miner and vehicle. Through the mobile Internet of Things technology, no matter which roadway has a problem, the monitoring personnel can grasp it in time through the “Industry and Mine Communication”, and quickly make analysis and processing, effectively improving the work of the coal mine’s intrinsic safety management.
With the help of “Gongmintong”, even if the managers are on business trips, the production status of the tunnels under the mine can be seen at a glance; if the gas and other data exceed the standard, there will be mobile phone text messages and even voice alarms to notify people; the mining production is intelligent, and many positions Has achieved unattended and automated control…
Some experts believe that although my country’s mine safety management is still in its infancy in terms of Internet of Things applications, it will be a matter of time before the Internet of Things enters more mines just like the “Industry and Mine Communication” management system helps the safety production of Jinan Mines. Because with the continuous deepening of information technology with the Internet of Things as the core, the system is used as a platform to effectively monitor the “downhole”, accurately locate personnel, and realize real-time monitoring and timely warning of people, environment, equipment and management. , Find the “first shot” that can affect the whole body, and realize the safety and zero accident through the non-neutral management and non-blocking system. This is an important step in the development of industrial and mining intrinsic safety management informatization, and it is precisely the key to the mobile Internet of Things that can help solve the problem of intrinsic safety in mines.
With the help of China Mobile’s “Industry and Mine Management System” for coal mine management, 13 coal mines in Jining, Shandong, including Jining Coal Mine of Shandong Yankuang Group and Xuchang Coal Mine of Zi Mining Group, and 40 coal mining companies in Gansu, Shanxi, and Hebei, etc. The use of safety analysis methods and control methods has been realized, and the local coal mines are also known as “safe mines”.
