1512 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. The shearer cutting speed and drum load were adjusted to match roof behavior and coal-wall conditions, while the scraper conveyor accommodated large and highly variable coal flow without interruption. This coordinated operation effectively reduced load fluctuations and minimized dynamic impacts on the system. 4.3 Field Commissioning and Operational Stability System commissioning was conducted in stages, beginning with low-advance-rate operation and gradually transitioning to full-capacity production. Particular attention was paid to roof behavior, coal-wall stability, support loading characteristics, and equipment response under strong mining-induced stress. Field observations demonstrated that the integrated system maintained stable roof control, effective coal-wall protection, and reliable coal transportation throughout the advancing process. No large-scale roof failures or uncontrolled coal-wall collapses occurred, confirming that the integrated design and coordinated operation strategy were suitable for sustained 10-m mining.
