%X Based on in-situ observation about stress in inclined coal pillar for fully-mechanized top-coal caving face of thinner coal seam and the elastoplastic limit equilibrium theory, taking the thickness and angle of coal seam into account, the results and relations are analyzed systematically and completely; and the formula and the distribution laws of stress peak value are obtained. The study will provide some references to the reasonable design for gateway and the determination of parameters for coal pillar preservation in the condition of gob-side driving in fully-mechanized top-coal caving face, and to improve the maintenance of gateway and increase the recovery ratio. And it will provide some available references for other similar mining areas.
