摘要:

矿区地表沉降预测时, 各沉降监测点观测数据不可避免地存在粗差, 导致监测点高程预测的偏离。利用抗

差估计原理解决观测值存在粗差时矿区地表的沉降预测, 研究结果表明, 当沉降观测数据中混有粗差时,

最小二乘拟合预测值严重偏离实际, 抗差估计法的沉降预测结果与实际沉降较吻合, 能很好地反映监测点

的沉降情况, 为矿区安全开采提供有效的数据保障。

Abstract:

When predicting the surface subsidence in mining areas, the observed data at monitoring

points inevitably exist gross error, leading to the deviation from predicting elevation of

observed points. The principle of robust estimation is used to solve the subsidence

prediction of mining area surface when there exists gross error in observed data. The results

show that when the observed data are mixed with gross error, the least square fitting

prediction data significantly deviate from the actual situation. The subsidence prediction

result by the robust estimation method is consistent with the actual subsidence, which can

truly reflect the subsidence at monitoring points, which provides effective data for ensuring

safe operation in mining areas.
