构造应力和节理耦合对采煤沉陷的控制作用分析

摘要

In order to improve the accuracy of coal mining subsidence design calculation and grasp the control effect of tectonic stress and joint coupling on coal mining subsidence,the paper analyzes the influence of different tectonic stress and different joint on coal mining subsidence by using FLAC finite difference program to establish numerical simulation model,which provides an effective design and analysis method for coal mining subsidence prevention.%为了提高采煤沉陷设计计算的精确性，掌握构造应力和节理耦合对采煤沉陷的控制作用，采用 FLAC 有限差分程序建立数值模拟模型，分析不同构造应力和不同节理条件下对采煤沉陷的影响，为采煤沉陷预防提供一种有效的设计分析手段。
