摘　　要：以陕北榆林某矿3#煤层主产工作面为工程背景,依据相似理论,采用相似模拟实验,从位移变化、裂隙演化及采动应力3个方面对工作面开采后覆岩移动破坏规律进行分析。实验得出近浅埋煤层"三带"特征、矿压显现特征及岩层位移特征。Taking the productive working face in third coal seam in Yulin as the engineering background,analogue simulation was made to analyzing it from three conditions which are change of displacement,crack evolution and mining stress.The experimental results obtained ＂three-zone＂characteristic of shallow buried coal-seam,mine pressure characteristics and strata displacement characteristic.

关 键 词：裂隙演化 相似模拟实验 关键层 近浅埋煤层
