摘　　要：为了解决无标准地表移动观测站的矿井能够使用次级地表移动观测站的实测资料,反演得到地表移动参数,从而指导本矿井的采煤规划设计等工作。基于最小二乘-层次分析法理论,采用多工作面大范围次级地表移动观测站的监测数据与概率积分法相结合,研究了次级地表移动观测站监测资料反演矿井地表移动参数的方法。使用该方法反演得到的地表移动参数计算采空区造成的采动影响范围,与现场实测、调研资料对比验证,结果表明,该方法反演得到的地表移动参数与本矿井的实际采动损害情况吻合,证明了该方法的正确性与合理性,解决了利用次级地表移动观测站监测结果高精度反演地表移动参数的问题。In order to solve the problem that practical data of secondary surface movement observation station could be applied in sur-face movement observation station with no standard, and then surface movement parameters obtained by inversion , so coal miningplanning and designing could be guided. Based on least square-generalized analytical hierarchy process, and combined monitoring dataof more working face and large scope of secondary surface movement observation station and probability integral method, surface move-ment parameters inversion method under monitoring data of secondary surface movement observation was studied. And then mining influ-ence scope that caused by gob under inversion data of surface movement parameters, compared with field measured, investigate andsurvey data, the results showed that surface movement parameters that obtained by the method could be identical as practical miningdamage. It proved the method is validity and rationality, and the problem that surface movement parameters could be inverted highlyprecision by the monitoring results of secondary surface movement monitoring observation station.
