摘　　要：本文以济宁三号煤矿研究区3上工作面的已有资料和3下工作面的实际观测数据为基础,对该区域地质条件下的煤矿重复采动时地表沉陷的规律进行了研究,解算出地表移动变形参数,基于邻近的工作面开采情况特点,分析地表移动情况及其影响因素。Based on the existing data of the upper working face 3 and the actual observation data of the lower working face 3 in the research area of Jining No.3 Coal Mine,this paper studies the law of surface subsidence during repeated mining in this area,calculates the parameters of surface movement and deformation,and analyses the situation of surface movement and its influencing factors based on the mining characteristics of adjacent working faces.

关 键 词：地表沉陷 重复采动 变形参数 规律分析
