沿空留巷顶板运动与巷旁支护阻力研究

Study on Roof Movement and Roadway-side Supporting Resistance of Remained Roadway

运用Winkler弹性地基理率,把沿空留巷巷道上方顶板看作弹性薄板条，建立了顶板运动力学模型，导出顶板的挠曲运动方程，分析了顶板内应力的分布特征，提出了计算巷旁支护阻力的新方法，并用示例进行了说明。

In accordance with the Winkler's theory of elastic ground and taking the roof above remainedrodaway as elastic thin lath,a mechanics model of roof movement has been set up,a movement equation of roofdeflection deduced,the features of stress distribution in roof analyzed,a new method of calculating supportingresistance put forward and a illustrating case accompanied as well.
