摘要
以大峰煤矿为研究对象,因其煤层较多,地质环境复杂,其边坡的稳定性具有一定的代表性,通过分析矿区地质及水文情况,利用边坡稳定性理论建立大峰矿实际边坡受力简图,得出边坡稳定性安全系数的人为影响因素为台阶高度和坡面倾角,并应用数值模拟技术,使用Fl AC3D三维模拟软件创建大峰矿边坡模型,分析大峰矿的边坡失稳性,得到边坡最终的位移、应力云图等特征,提出有效合理的防护措施,预防安全事故的发生。
Taking Da Feng coal mine as the research object,because of its coal seam is more,complex geological conditions,the stability of the slope has certain representativeness,through the analysis of geological and hydrological conditions,using the theory of slope stability to build large peak mine actual slope stress diagram,it is concluded that the slope stability safety factor of the human factors as bench height and slope Angle,and the application of numerical simulation technology,the use of Fl AC3D three-dimensional simulation software to create large peak mine slope model,analysis of slope stability,large peak mine slope which features such as displacement,stress nephogram,put forward effective reasonable protective measures,to prevent the occurrence of safety accidents.
