【摘要】 以大隆井田为例,应用地质动力区划方法划分了井田Ⅰ~Ⅴ级断裂.以Ⅰ~Ⅴ级断裂构成的井田地质断块为基础,采用有限单元法弹性力学平面应变模型,获得了井田构造应力的最大主应力和最小主应力等值线图.根据大隆矿构造应力分布状况,分析了井田井构造应力对巷规划设计的影响.更多还原

【Abstract】 Dalong mine field was divided into Ⅰ ~ Ⅴ level faults,using geological power division method.Based on the mine field geological fault block which is constituted byⅠ~Ⅴlevel faults,using the finite element method elastic plane strain model,the maximum principal stress and minimum principal stress contour map of mine field tectonic stress are obtained.According to the Dalong mine tectonic stress distribution,the influence of mine tectonic stress on planning and design of lane is analyzed.更多还原
