The chute scraper conveyor must use a coal baffle, and be tied to the single column near the sidewalk side of the advance support with iron wire. Before moving the scraper conveyor, the floating coal on the working face must be cleaned, the bottom plate must be flat, and the temporary columns must be removed in time. The single hydraulic prop shall be used for pushing according to the actual situation of the working face. The moving step distance of the scraper conveyor is 1.2m, and the moving sequence is head to tail, tail to head, and middle to both ends. After moving, the scraper conveyor shall be kept flat, straight, stable, and firm, and the head and tail pressure pillars shall be made in time. The length of one push scraper conveyor shall not exceed 30m. During sliding, the sliding section shall be hung up with the beam and hit with the coal wall pillar before sliding. To prevent the scraper conveyor from being disconnected, the minimum bending section of the scraper conveyor shall not be less than 15m during sliding. The basic column shall be erected in time after the moving and sliding work is completed, and the roof can be returned only after the basic column is recognized and the floating coal is clean. When moving the scraper conveyor, pay attention not to squeeze the hydraulic pipe and cable. The operator should slowly inject liquid to move the conveyor. At the same time, he should always observe the rooting condition of the side pillar of the old pond, whether the coal wall pillar is secure, and whether the coal wall is flaking. In case of any abnormality, stop handling immediately. After the scraper conveyor is pushed in place, the prop shall be timely added, and the prop replaced during sliding shall be timely added. When it is necessary to change the column, the principle of supporting before changing must be implemented.
On October 30, Li Zhenbo, General Manager of Information Technology at Shandong China Coal Group and General Manager of Zhongyun Group, was invited to deliver a keynote presentation at an activity organized by the Teaching and Research Group of the Shandong Province Technical and Vocational Schools Admissions and Employment (Industry-Education Integration) Center. The event brought together 23 technical and vocational schools across the province and focused on innovative integration of artificial intelligence with technical and vocational education, sharing practical achievements from the front lines of industry and jointly exploring new approaches to cultivating versatile digital-skills professionals through school-enterprise collaboration.
Recently, the Zhongmei Zhiren AI system, independently developed by the Intelligent Research Institute of Shandong China Coal Group, has continued to evolve and improve. Drawing on core technologies including large language models (LLMs), retrieval-augmented generation (RAG), AI agent workflow orchestration, multimodal vision, and audio and video generation, it is building a dedicated end-to-end AI platform for China’s industrial and mining supplies sector. The platform uses independently controllable AI technology to support the digital transformation of domestic and international trade and foster new quality productive forces.
Recently, three sets of software independently developed by Shandong China Coal Industry & Mining Supplies Group Co., Ltd. have successfully passed the review of the National Copyright Administration and obtained the Computer Software Copyright Registration Certificates. The three certified achievements are all built-in agent modules of the China Coal Zhiren AI System, namely: China Coal Zhiqing Image Management Tool V1.0, China Coal Construction Machinery Foreign Trade Independent Website System V1.0, and China Coal Mining Machinery Foreign Trade Independent Website System V1.0. This marks the continuous expansion of the ecological layout of the China Coal Zhiren AI System and the further consolidation of self-developed technical barriers.
Shandong China Coal Mining Support Equipment Co., Ltd. was founded in the 1990s with more than 1100 employees. It now has 53 professional companies, 3 Hong Kong companies, 1 British Cayman company and 1 American company. It is a large diversified industrial group integrating intelligent equipment manufacturing, e-commerce, software research and development and intelligent logistics, which is cultivated and supported by the Ministry of industry and information technology, the Ministry of Commerce, the development and Reform Commission, Shandong Province and Jining City.
