摘　　要：针对用进路法回采顶柱的人工假顶暴露形状为矩形的矿山地下结构 ,应用薄板理论和能量原理对其稳定性进行分析。通过建立进路结构力学模型 ,得出了假顶变形阶段的挠曲、应力与假顶的强度、受力及工程尺寸等参数的关系式 ,并具体应用于新城金矿的顶柱回采实践中 ,结果表明The thin plate theory and energy principle were applied in the analysis of the stability of the artificial roof in drift stoping of crown pillar,whose exposed shape was of retangular mine underground structure,the relationships between the parameters such as the deflection,stress and strength of deforming artificial roof and the engineering size were found and used later in the crown pillar stoping practice at Xincheng Gold Mine.The results show it is of good guidance significance in the real production to analyse the stope stability by this theoretical method.
