1. Calculate the peak value of conveying driving tension and its occurrence conditions during the operation of the conveyor. The peak value of the conveying driving tension is usually several times or even more than ten times of its normal operating tension, and the tension value calculated according to the previous static design method is much smaller than the actual value, so the safety factor can only be increased to ensure the safe operation of the conveyor. In the absence of reliable analysis tools, the safety factor determined by empirical methods is often too large, which will inevitably lead to rising costs and waste of investment.
2. The vibration characteristics of the conveyor belt in operation are analyzed. Vibration is the main reason that leads to the increase of conveyor driven tension, and it is also the culprit that causes the belt breaking accident. To find out its rules is of great significance to effectively control the conveyor driven tension.
3. The influence of boundary conditions on the vibration of conveyor belt is studied. The boundary conditions of conveyor belt refer to all internal and external conditions that affect the dynamic characteristics of conveyor belt, such as driving device, tensioning device, idler, load, etc. The influence of the change of these boundary conditions on the vibration is analyzed and studied, and the optimal form of the boundary conditions for optimizing the vibration characteristics of the conveyor belt is found; The comprehensive index of performance and economy is optimal.
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.
