摘　　要：为获得房柱式采煤法残留煤柱回采时的顶板变形、破坏特征和顶板应力分布规律,根据山西煤炭运销集团阳城西河煤业3#煤层残煤资源长壁式复采进行三维相似模拟试验。复采过程中对煤层的直接顶、基本顶的应力、位移进行观察、记录,模拟过程再现了顶板下沉、断裂、垮落以及对采煤工作面的影响全过程。通过试验观测与数据分析演化,研究残煤复采过程中顶板的应力变化对顶板初次来压与周期来压以及顶板垮落的影响。For obtaining the roof deformation and destruction feature and stress distribution rule in residual coal mining after the room and pillar on the basis of longwall residual coal mining of 3#coal seam in Xihe mine, Yangcheng of Shanxi coal transportation and sale group, the three-dimensional simulation experiment was established. In the mining process the experiment observed and recorded the stress and displacement of the immediate roof and main roof,it is reappeared the roof subsidence,breakage, collapse and the influence to the coal mining working face. Through the analysis and evolution of experiment data, researching the roof stress behavior in the residual coal mining was done.
