"Smart security" for the mine escort

Based on five ten million tons of open pit coal mines, to intelligent safety, to information control risk. State Power Investment Inner Mongolia Company vigorously implements scientific and technological innovation and intelligent construction, and creates a "smart security" control system for open-pit coal mines, which provides many beneficial references for safe and efficient intelligent mining of open-pit coal mines.

Wisdom enables "dynamic" regulation

"There is a production control vehicle 30 meters ahead, please maintain a safe distance and proceed slowly through the intersection." Hearing the prompt of the intelligent safety control platform, Sun Jian, the driver of the dump truck, adjusted the operation in time and drove slowly through the intersection.

"The transport dump truck I drive is 11.5 meters long, 7 meters wide and 5.9 meters high, and there is a certain driving risk by observing the road conditions with the naked eye." The intelligent safety management and control platform can predict driving risks in advance, which greatly improves the safety factor." Sun Jian, who has worked for more than 20 years, told reporters.

Focusing on the two core businesses of "5G+ vehicle transportation", Zahanauer Coal Industry Company has directed the development and application of vehicle intelligent security systems, centralized data integration and functional integration of 17 sets of vehicle security systems, and built a three-in-one safety management model of "human-vehicle-tube" in open-pit coal mines.

The reporter found that 360° wide-angle cameras, AI recognition cameras and anti-fatigue cameras were installed inside and outside the vehicle to achieve full regulatory coverage; In the production dispatching command center, through the intelligent security management and control platform, potential unsafe behaviors can be effectively monitored, achieving all-weather supervision.

"We have changed from the original 'static' supervision to 'dynamic' supervision, and truly built a new safety supervision model of 'vehicle-vehicle coordination, vehicle-road coordination, human-vehicle cooperation'." Zahanauer open-pit coal mine science and innovation department director Zhang Wei introduced.

Smart warning "plus code" security

From the 1.0 iteration upgrade to 3.0, the number of hidden dangers of Zahanur Coal Company was reduced by 27% and the number of violations was reduced by 46%. "The research results have cracked the technical bottleneck of the safety of open-pit vehicles and personnel, and we have obtained an invention patent, a utility model patent, and formulated an enterprise standard and published a core journal paper." Zahanauer coal company party secretary, chairman Jiang novelty said.

The innovation achievements were fully promoted in the two minmetals of the State Power Investment Inner Mongolia Company, and Baiyin Huameng East Coal Industry Company customized the intelligent security system of vehicles to continue to "increase" the safety risk control of rammed slope.

"At present, slope management is the top priority of open pit mine safety production. We have set up three radars and 64 GNSS monitoring points at the site to achieve all-weather, real-time dynamic monitoring of all slopes in the area without dead corners." Yu Xin, director of the Science and Innovation Department of Baiyin Huamengdong Coal Industry Company, introduced, "Once the first and second alarm occurs, the system will automatically demarcate the electronic fence within the 200-meter range of the alarm point, and warn surrounding vehicles to evacuate in time through the voice announcement of the vehicle terminal, further improving the timeliness and accuracy of slope emergency management."

It is understood that the vehicle intelligent security system has been successfully promoted and applied to nearly 1,200 sets of mining equipment in Datang International Xilin Hot Mining and Xinjiang Yihua Mining, and the value of promotion and application in the industry has been further improved.

Wisdom drives "no one" change

Combined with the actual situation of the site, Baiyinhua open-pit mine took the lead in the construction of the ground coal conveying system tape machine with few people/unattended, and successfully broke through the traditional production mode of "man marking man" and "civil defense material" for the coal conveying system.

As the first management platform in the open pit coal mine in Inner Mongolia Autonomous Region to realize the unattended management of the whole process of the coal transport system through intelligent technology, this project can realize the self-test of the condition of the coal transport system's start-up readiness and remote one-click intelligent control, effectively reducing the equipment failure shutdown rate by 25%-40%, and is expected to reduce the coal transport personnel by 30%.

"We installed an intelligent inspection robot on the 240-meter-long coal conveyor with a 12-degree slope to realize all-day monitoring. The robot conducts autonomous inspection every four hours, and each inspection takes about 1.5 hours. After completing the inspection, the robot will automatically return to the charging room for charging, making the 'unmanned inspection' safer and more efficient." Said Wang Yan, director of coal processing department of Baiyinhua open-pit mine.
