地表动态下沉函数模型的构建及研究

摘要

地下资源开采引起地表下沉的问题比较复杂,本文构建了动态下沉预计函数模型,提出了地表主断面上动态下沉过程的计算方法,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:该动态下沉预计函数模型能够反映地表下沉的动态特征,可以更加准确的预计出地表动态移动,很好的解释一些采动现象,对指导煤矿生产实践具有重要的现实意义.%Due to the complexity of the surface subsidence of underground mining,this paper constructs a dynamic subsidence prediction model,a calculation method is proposed for dynamic process of surface subsidence of main section,and Shanxi city of Yangquan province Shangshe 82041 West face data were verified,and concluded that the dynamic subsidence prediction model can reflect the dynamic characteristics of surface subsidence,can more accurately predict the dynamic surface movement,a good explanation of some mining phenomenon,has important practical significance to guide the practice of coal mine production.
