摘要
为了解决目前采空区利用率普遍较低的现象,提高土地资源的利用率,采空区治理显得尤为必要.首先从介绍数值模拟FLAC3D软件的基本原理入手,采用数值模拟计算方法分析采空区稳定性.针对具体的工程实例,利用数值模拟软件FLAC3D对南马圈煤矿和村民自采小矿采空区的稳定性进行定量分析;通过监测地表沉陷历史过程及观测采场围岩破坏情况,较真实地再现了围岩变形的破坏过程,尤其是塑性区的发展过程;通过观测采空区破坏的形式及采空区破坏的特征,为治理采空区提供了理论依据.
The use of the waste cave is generally lower at present, to slove the problem, increase using land resource and storing the waste cave has become necessary. Firstly, the paper introduces the principle of the FLAC^3D which is a numerical simulate software and use numerical simulate to analyse the waste cave＇ s stability . According to concrete project gives a real example： the waste cave＇s stability of Nanmaquan coal mine and Mincai small coal mine , analyses the stability by use of the FLAC^3D programm, observes the process of sedimentation about the earth＇s surface and the destroying of wall rock about the coal mine, taking on a new look about the process of the wall rock＇ destroying really specially about the state zone. By observing the waste cave＇s deslroying, to give a theoretical base of restoring the waste cave .
