摘　　要：神东煤炭集团昌汉沟煤矿15104工作面的开采深度约150 m,埋深浅、基岩厚、上覆松散沙层薄是该矿区煤层的典型赋存特征。采用理论分析并利用FLAC3D软件建立了数值计算模型,分析了采动影响下回采巷道应力分布情况和变形特征,预测了围岩的稳定性。With a mining depth of only about 150m at the #15104 face in Changhan＇gou coal mine of Shendong Coal Group,coal seams of this mining area are mainly characterized of shallow depth,thick bedrock and thin overlying loose sandy strata.Utilizing theoretical analysis and numerical simulation model FLAC3D software,numerical calculation model is established.The paper analyzes the stress distribution and deformation characteristics of gateroads under the influence of coal mining operation,The paper also predicts the stability of surrounding rocks.
