摘　　要：为了解决某矿开采沉陷的问题,建立了地表移动观测站进行观测。通过实地观测、地表移动变形参数计算,并利用概率积分法进行模拟,分析了地表移动变形规律,获得了本区地表移动变形参数和预测参数与地质采矿、地形地貌的关系,为该矿煤炭合理开采和各类煤柱的留设提供依据。To solve the mining subsidence in a mine, we established surface movement obser-vation stations. Through the on-site observation, calculation of surface movement and deforma-tion parameters, and simulation by probability integration method, we analyzed the surfacemovement and deformation law to obtain the relationship between the surface movement and de-formation parameters and predicted parameters with geological mining and topography in this are-a,which could provide a basis for the retention of various types of coal pillars in the mining area.
