地下资源开采引起地表位移的问题比较复杂,采用2种方法构建了动态预计函数模型,并用山西省阳泉市上社煤矿82041西工作面的实测数据进行了验证,得出结论:Knothe模型有其局限性,第2种动态函数模型能够反映地表2种移动3种变形动态特征,可以更加准确地预计出动态下沉、动态水平移动及动态变形值,同时能够理想地表达出地表下沉速度和地表下沉加速度的变化规律,对指导生产实践具有重要的现实意义。
The problem of surface displacement caused by underground resources exploitation is rather complicated. Two kinds of methods are used to construct the dynamic prediction function model. The results are verified by the measured data of the 82041 west face in Shangshe Coalmine, Yangquan City, Shanxi Province. The conclusion is that the Knothe model has its limitations The second kind of dynamic function model can reflect the dynamic characteristics of the three kinds of deformation of the two kinds of movement on the earth’s surface so as to predict the dynamic subsidence, dynamic horizontal movement and dynamic deformation value more accurately and at the same time can express the surface subsidence speed and surface The law of the variation of the sinking acceleration has important practical significance in guiding the production practice.
