摘　　要：针对某煤矿1501工作面地表存在村庄建筑,为了确保村庄建筑的正常使用,以地表移动观测站实际观测数据为基础,通过建立坐标-时间坐标系,运用概率积分法对由于1501工作面开采引起的地表移动变形随时间和空间的变化规律进行研究,分析该工作面开采不同时间对上方村庄建筑物的采动影响。结果表明:通过概率积分法建立的坐标-时间预计函数可以准确地描述开采过程中任意时间点的地表整体移动变形,能够满足工程实践应用。In order to ensure the normal use of village buildings above 1501 working face of a coal mine, on the basis of the surface movement observation data, we study the laws of surface movement and deformation caused by 1501 working face mining by means of the probability integral method through the establishment of time-coordinate coordinate system. The results show that the expected function can accurately describe the global deformation of the surface at any point in the mining process, which meets the practical application of engineering.
