Abstract: With underground measurements and similar material analogy modeling, the authors analyzed distribution of induced stresses in roof and floor of the seam, and the state of hydraulic supports and the single spile. The results show that supports have different sustaining states at different locations, of which the biggest abutment stress is located at the middle part of working face. For the same support, the abutment stress of the front columniation is larger than that of back one. The stress in surrounding rock of the ventilation entry is bigger than that of conveyor entry with a peak value of stress at a distance of 3 to 11 meters from the working face. The mining-induced stress in the same roof strata varies with the distance from the working face, and it also varies from one stratum to another. The larger the stress is, the closer the stratum is located to the coal seam. The largest stress is observed at a distance of 6 meters from the working face, while zero stress is at the working face. This study provides guidelines for design and management of the longwall top-coal caving, entry support and roof control.
