某矿9^#煤顶底板采动效应数值模拟

摘要: 以某矿9^#煤9418工作面为研究实例建立工程地质模型,在分析其工程地质、水文地质及开采条件的基础上,采用FLAC^3D有限差分数值计算软件对工作面推进过程中顶底板的采动破坏规律进行数值模拟,得到了工作面推进过程中顶底板应力场、位移变形及塑性破坏区的基本发展变化规律,为煤矿安全生产和煤矿水害防治提供参考依据。

Abstract: An engineering geological model is established by taking the 9418 working face in a mine No.9 coal as an example.On the basis of analyzing engineering geological,hydro-geological and mining conditions of the mine,the finite difference software of FLAC^3D is utilized to simulate the mining and damage laws of the roof and floor caused by working face advancing.The basic development changes laws of the stress field,displacement deformation and plastic failure zone of the roof and floor during the process of working face advancing were obtained.And this would provide preference for the mining safety and the prevention of the water-inrush.
