263 This integrated approach ensures stable interaction among all components under extreme loads and dynamic conditions, enabling continuous, high-efficiency production and forming the technical foundation for the world’s first successful 10-m fully mechanized longwall mining operation. 4. System Integration and Field Implementation 4.1 Overall Longwall System Configuration The 10-m fully mechanized longwall system was configured as a highly integrated production unit, consisting of 10-m height hydraulic shields, a 10-m cutting-height shearer, and an ultra-large-capacity scraper conveyor. All components were designed and matched to operate under conditions of ultra-large excavation space, strong ground pressure, and high coal output, ensuring mechanical compatibility and stable system behavior. The working face had a length of approximately 300 m and an advancing length of nearly 6 km, representing a full-scale industrial application rather than a pilot test. Equipment layout, operating parameters, and advance rates were optimized to maintain continuous production while ensuring roof and coal-wall stability. A simplified system layout of the 10-m longwall face is illustrated in Fig.4. Fig.4 Configuration of the 10-m fully mechanized longwall mining system. 4.2 Coordinated Operation of Key Equipment Under 10-m mining conditions, isolated optimization of individual machines is insufficient. Stable operation relies on coordinated interaction among shields, shearer, and conveyor. During field implementation, coordinated operating sequences were established to ensure that cutting, support advance, and coal transportation proceeded in a controlled and synchronized manner. The hydraulic shields maintained continuous high-resistance support to the immediate roof while providing timely coal-wall protection during shearer operation.
