摘要
以理想散体移动模型为基础,提出了更具有一般统计意义的采动覆岩与地表下沉概率密度新函数,建立了水平煤层开采地表下沉和变形的预计新体系,为矿山开采地表下沉和变形预计提供了新方法。
The paper puts forwards a new probability function of mining overlying strata and subsidence that has a general statistical significance based on the ideal stochastic medium displacement model. It establishes a new system of pre calculation on horizontal mining subsidence and deformation, which gives a new method for prediction on mining subsidence and deformation.
