摘　　要：唐口煤矿现有采区宽条带开采的地表移动观测资料表明,区域地表移动变形曲线基本符合正态分布特征。采用概率积分法对观测下沉曲线进行最佳迭代拟合,将误差减至最小求取采动变形预测参数,并对430采区工作面开采叠加后对地面村庄房屋的损害程度进行了分析、评价,结果表明村内房屋属于极轻微或轻微损坏,针对不同房屋结构特点,提出了相应的维修、保护措施。The existing observed data of surface movement in Tangkou Coal Mine indicates that the regional surface deformation curves conform to the normal distribution characteristics basically. The authors made the best iterative fitting of observation subsidence curves with the probabilistic integral method and reduced the error to the smallest scope so as to get the prediction parameters of deformations, and carried out the analysis and evaluation of the damage degree for the villages and surface buildings after deformation superposition of mining all coalfaces in No. 430 mining area. The results indicated that buildings in the villages were slightly damaged and the corresponding maintenance and reinforcement measures were proposed.
