摘要: 针对塌陷地动态治理亟需解决地面动态沉陷精准预测这一问题,采用理论分析和实测研究相结合的方法,从分析地面点动态沉陷过程为入手,明确了地面点动态沉陷过程中下沉量、下沉速度和下沉加速的变化规律,在此基础上,建立了符合地面点动态沉陷演化过程的基于Hill函数的动态沉陷预测模型,并采用济三煤矿5316工作面、东滩煤矿3307工作面和义能煤矿CG1301工作面的地表沉陷实测资料对模型进行了验证,验证表明各案例的相对中误差均可控制在3%以内,说明此模型能够很好的实现地面点的动态沉陷预测。

Abstract: In order to solve the problem of accurate prediction of ground dynamic subsidence in the dynamic control of subsidence land, this paper adopts the method of combining theoretical analysis with field measurement. Starting from the analysis of the dynamic subsidence process of ground points, the variation law of subsidence, subsidence velocity and subsidence acceleration in the dynamic subsidence process of ground points is clarified. On this basis, a dynamic subsidence prediction model based on Hill function is established, which conforms to the evolution process of dynamic subsidence of ground points. The model is verified by the measured data of surface subsidence in 5316 working face of jining No.3 Coal Mine, 3307 working face of Dongtan Coal Mine and CG1301 working face of Yineng Coal Mine. The results show that the relative error between the predicted value and the measured value is controlled within 3%, indicating that this model can well realize the dynamic subsidence prediction of the ground point.
