摘要
漠滨金矿为一中低温贫硫化物石英脉型变质层控金矿床.矿脉产出严格受断裂控制.本文运用有限单元数学方法模拟该矿区构造应力场,结果显示最大主压应力和最大剪应力分布与断裂分布相一致,且在多组断裂交汇部位,最大主压应力和最大剪应力值最集中,矿化最好.根据应力值分布趋势可预测靶区.
The Mobin gold deposit is a. low-medium temperature, sulfide-poor and gold-bearing quartz vein deposit. The orebodies are strictly controlled by fractures and mainly occur at the intersections of these fractures. The auther has researched the ore-controlling fractures by the finite element method. The results are as follows;(1) The maximum principal press stress(σ1) and the maximum shearing (τ) strees coincide with the ore-controlling fractures. (2) The values of a and τmax are concentreted in the intersections of these fractures, where mineraliztion is considered to the best. Based on this research, the author considers that much attention should be paid to the southwest of the gold mine where the concealed industrial orebodies might be found.
