摘要
本文通过对大量现场观测资料的综合分析,研究了山区煤矿地下开采引起的地表移动与变形规律。文章首先应用叠加原理探讨了采动滑移与地形的关系,然后对采动滑移机理和滑移向量进行了分析,提出了典型地貌等影响开采的滑移变形模型,讨论了非典型地貌和非等影响开采滑移变形的分布规律,最后建立了新的山区地表移动预计数学模型,并给出了计算实例。本研究成果可用于山区地表移动预计及煤柱留设与压煤开采设计。
Based on observation data,this paper studied laws of ground movement and deformation due to underground extraction of coal in mountainous areas. Firstly,the paper analyzed the relation between sliding and topography by using the principle of superposition of surface movements.Then it analyzed mechanism of sliding and its vectors.It put forward a sliding deformation model of typical landform under equivalent extraction,and the distributive laws of non-typical landform and non-equivalent extraction were discussed.Finally,a new mathematical model for prediction of ground movement in mountainous areas was established,and an example of calculation was given.This can be used in prediction of ground movement in mountainous areas,and used for design and extraction of pillars.
