With a finger, AI conducts dynamic diagnosis of mine safety production, prompts loopholes and weaknesses in daily management, and resolves hidden dangers in a "bud" state; with a click of a mouse, AI intelligent inspection robot automatically inspects equipment...

Since the beginning of this year, No. 1 Coal Mine has continued to increase investment in the safety field, comprehensively improve its comprehensive protection capabilities, keep the pulse on track, and improve the cloud-based, systematic, intelligent, industry-oriented, and scene-oriented level of intelligent supervision, building a solid foundation for mine safety production.

AI makes devices speak "Mandarin"

"NOSA Safety, Health and Environmental Risk Warning, you have entered a dangerous area, please leave quickly..." At 8 o'clock on March 23, at the 1013 intelligent fully mechanized mining face underground of the mine, Wang Huifeng, a coal machine overhauling worker of the first fully mechanized mining team, was reminded by the voice alarm of the "AI+NOSA" intelligent risk management and control system, quickly left the dangerous area of advanced support.

"This is why the AI+NOSA intelligent risk management and control system locks all equipment and issues a voice alarm after identifying simulated violators on the spot. It not only sends alarm information to the command center as soon as possible, automatically saves the violation video, but also uses sound, light and voice on the spot., issue reminders to violators." Sun Fei, deputy director of the Information Department of No. 1 Coal Mine, was saying when a pop-up window suddenly appeared on the large screen of the control room, showing that employees at the 1013 Intelligent Fully Mechanized Mining Face had broken into the dangerous area. Sun Fei's explosion-proof mobile phone Mobile device also received the same message reminder.

The system integrates many cutting-edge technologies such as AI recognition, Internet of Things, and cloud computing. It captures personnel action data through video, and then compares the data to identify, track, judge, and capture expressions, movements, etc., and intelligently analyzes safety issues existing in coal mine production and operations, and provides advance warning to ensure personnel safety.

"A hole as big as a needle tip can leak through the wind as big as a bucket. The AI+NOSA intelligent risk management and control system instantly and intelligently identifies unsafe behaviors of people and unsafe equipment, achieving continuity, comprehensiveness, transparency, and all-weather intelligent marking without dead spots in key production links." Liu Maorong, deputy director of No. 1 Coal Mine, has been involved in the construction of the system. He obviously understands the advantages of the system better than ordinary employees.

"Wisdom" achieves "hard core" strength. Since the system was put into use, the incidence of "three violations" in No. 1 Coal Mine has dropped significantly. Employee work violations have dropped by 17.4% annually. Unsafe behaviors and non-standard operations have dropped by an average of 8.6% per month, and the number of hidden dangers has dropped by an average of 10.3% per month.

AI "takes the pulse" for belt transportation

"This is the intelligent centralized control center of the main transportation system. After system monitoring, the 506 #belt carrier idler of the main transportation belt in the north and the first and second parts of the main transportation belt is high. Please repair it. There are Level 3 large sections in the tail of the North 11 aircraft. Please clean them in time." The mining intelligent brain AI artificial intelligence platform immediately informed Wang Jian, a technician who was inspecting the belt conveyor.

On March 24, in the intelligent centralized control of the mine's main transportation system, 4 large screens and 36 module and small sub-screens monitored key points such as the loading point, driving part, and tape storage bin of the underground transportation system in real time. When there are abnormal conditions such as large coal gangue, anchor rods, conveyor belt deviation, conveyor belt tearing, conveyor belt frame reversal, roller overheating, etc. in the picture, the green box automatically generated by the system will circle the abnormal points and move with the position.

In order to improve the safety and reliability of the main transportation system and improve the intelligence level of the mine, No. 1 Coal Mine has built a mine intelligence AI artificial intelligence platform to identify and analyze the coal volume, foreign matter, coal pile and deviation of the conveyor belt of the main coal flow transportation system, identify and alarm the real-time coal volume, calculate the size of coal flow on the belt and the volume of the belt, monitor the intrusion of dangerous areas, the overheating of conveyor belt bearings and rollers, and realize the whole coal flow control area Video detection, Intelligent alarm locking of hidden dangers improves system response speed and improves on-site safety management and control.

"The main transportation system of No. 1 Coal Mine has 11 fixed belt conveyors, with a transportation distance of about 27 kilometers; there are 3 coal bunkers, 6 coal feeders, 24 water silos for drainage, and 28,000 meters of water supply pipelines., 7600 meters of drainage pipeline equipment. After the intelligent centralized control operation of the autonomous transportation system, the service life of the belt has been extended from the original 60 months to 80 months, the number of maintenance and inspection workers has been reduced by 10, and the average monthly production cost has been saved by more than 500,000 yuan." Niu Zhanhai, captain of the mine's belt team, said.

AI empowers the "clean coal strategy"

AI empowers the "clean coal strategy"

"This is the AI super brain of our coal preparation center. It has global perception, global collaboration, and full-line intelligence. With the click of a mouse, you can switch images at will and view the production status of each post." Dispatcher Zhao Yue said in the centralized control and dispatch room of the Coal Selection Center of No. 1 Coal Mine.

Since the beginning of this year, No. 1 Coal Mine Preparation Plant has continued to deepen the "clean coal strategy" and fully applied advanced technologies such as big data, cloud computing, the Internet of Things, and artificial intelligence to build a "coal preparation AI super brain platform with global perception, global collaboration, and full-line intelligence.", an intelligent management and control platform and a 3D visualization system have been built to display the scene structure and equipment layout in the factory in a three-dimensional form, and production data, technical indicators and parameters, equipment operating status, Real-time data such as environmental energy consumption is uniformly connected to the platform and matched and integrated with information models to form a complete video sensing and safety monitoring system, realizing real-time monitoring and intelligent production of coal quality, unsafe personnel behavior, and equipment operating status. For the purpose of intelligent scheduling and intelligent prediction and early warning, an intelligent management service system of data interconnection, service sharing, and information synchronization is formed between various systems, achieving the goal of "unattended, manned inspection, energy conservation and safety, The purpose of efficient operation."

"The coal preparation plant takes AI model empowerment as the core, organically combines production intelligent control, video surveillance, equipment safety management, and data platform sharing, turning the dream of 'guarding' the workshop in the centralized control room into reality. With intelligence 'hard-core' weapons backed by, we are confident and determined to complete various production goals and tasks throughout the year." Guo Fengtao, director of the mine's coal preparation plant, is full of confidence.

Scientific and technological innovation has borne fruit. Through wisdom first and equipment technology upgrades, coal preparation plants have made a qualitative leap. It not only reduces the labor intensity of employees, improves the safety factor, reduces the mechanical accident rate, and can increase economic benefits by more than 60 million yuan every year.
