新疆哈图金矿控矿断裂分布特征及应力分析

Structure Controlling Fault DEistribution Characteristics and Stress Analysis of Xinjiang Hatu Gold Deposit

对哈图金矿区域控矿断裂和矿区地表及地下450～1 000 m深处的含矿断裂产状进行了统计,解析了矿区断裂构造形成的应力状况。根据含矿断裂产出和分布特征及变化规律,总结出哈图金矿区深部含矿构造的形成机制。通过对断裂构造级次的划分和配套,大致判断出含矿构造形成过程中的应力场变化趋势,为金矿深部隐伏矿体的预测提供了重要依据。

Hatu gold ore region in controlling fracture,mine surface and underground 450~1 000 m deep ore-bearing fault of statistics were made on the occurrence. We have also made an analysis of faulted structure formation stress condition. According to the ore bearing fault occurrence and distribution characteristics and variation law,we still summed up the formation mechanism of Hatu gold deposit area deep ore in bearing structure. Through the division and matching of fracture structural grade,the variation trend of stress field during the formation of ore bearing structure is roughly judged,which provides an important basis for the prediction of deep concealed orebody in gold deposits.
