摘　　要：通过对山东某矿地表密集建筑物压煤区开采条件及建筑物抗变形能力分析,提出了多个密集建筑物下压煤开采方案,采用概率积分法对开采方案进行了地表移动变形预计,并对建筑物损害程度进行了评估,通过综合对比分析,确定条带开采方案既能够满足地表变形要求,又能够有效保护地面建筑物安全,且经济、生态效益最优。Based on the analysis of the geological conditions and the anti-deformation ability of the surface dense buildings in a coal mine in Shandong Province,several coal mining schemes under dense buildings were put forward.Probability integral method was used to predict the surface movement and deformation of the mining scheme,and the damage degree of buildings was evaluated.Through comprehensive comparative analysis,the strip mining scheme could not only meet the requirements of the surface deformation,but also protect effectively the safety of the ground buildings,and had the best economic and ecological benefits.
