Progress in The Development of Coal Mine Large Models and Underground Backfill Technology in Shanxi, China

en.Wedoany.com Reported - Huayang No. 2 Mine, located in Yangquan City, Shanxi Province, China, an old traditional mine with a depth of 400 meters, has achieved an intelligent upgrade in underground safety management through the deployment of an AI coal mine large model. Dense sensors and multiple cameras are deployed along the mine roadways, enabling the AI early warning platform to conduct real-time monitoring of hazardous scenarios, such as not wearing a safety helmet or improper riding, using the AI coal mine large model.

Wang Li, Director of the Safety Inspection Department at Huayang No. 2 Mine, stated that the introduction of the AI coal mine large model has automated underground monitoring, effectively improving mine safety levels. Additionally, the Shanxi Coal industrial internet platform, operated by Shanxi Jinyun Internet Technology Co., Ltd., has listed nearly 1,500 AI application products, promoting the large-scale application of the AI coal mine large model across more than 280 coal mines in Shanxi Province.

In the area of solid waste treatment, Shanmei International Baozigou Coal Industry Co., Ltd., located in Pu County, Linfen City, Shanxi Province, China, has introduced coal gangue backfill technology, processing coal gangue into slurry for backfilling into rock fissures. By deploying underground intelligent dry sorting machines, it enables the direct sorting of coal and coal gangue in goaf areas and in-situ backfilling, with 40% of the 700,000 tonnes of coal gangue generated annually now processed through underground intelligent dry sorting machines for backfill.

Liu Yunlong, Chief Engineer of Baozigou Coal Industry, explained that the system uses intelligent dry sorting machines and backfill technology to achieve "zero waste on site," and plans to achieve 100% coal gangue underground backfill in the future. Currently, a ground-level coal preparation plant that had been in operation for years has been shut down, marking a new phase of large-scale application of underground backfill technology in coal mining operations.
