组合预测模型在矿区沉降预测中的应用

Application of Combine Model in Prediction of Mining Area Subsidence

为了准确掌握矿山开采面上部地表的沉降变化规律,预测沉降发展趋势,提出一种双曲线法与三点法的组合预测模型进行矿区沉降预测的方法。结合矿山沉降观测实例,采用单一的双曲线法、三点法以及两者的组合预测方法对沉降数据进行预测分析,对比其预测精度。结果表明,组合预测模型能够满足矿区沉降预测的精度要求,且预测精度优于单一预测方法。

In order to accurately grasp variation law of mine subsidence and predict trend of subsidence,the paper proposed a prediction method of mine area subsidence by using hyperbolic and three-point combine prediction model.Combining with an instance of subsidence observation,using single hyperbolic and three-point prediction model and the combining of two models to analyze and predict the settlement dates,comparing the forecasting precision.The results showed that the combine model meets precision requirements of prediction of mine area subsidence,and the prediction precision is more better than single prediction model.
