摘要
石坞金矿床位于钦杭东段成矿带之萍乡-德兴铜金银多金属成矿亚带之金山金矿田内,矿区出露主要为新元古界张村岩组上段第二亚段地层,工程岩组划分有松散岩组、软弱岩组、半坚硬岩组及坚硬岩组4个类型。在分析总结矿区工程岩组类型、结构面、岩体质量的基础上,对矿区工程地质进行了评价,并对矿区采空区及露天废石堆等主要工程地质问题提出了相关防治对策,为后续矿山开采提供了参考。
The Shiwu gold deposit is located in the Jinshan gold field of the Pingxiang-Dexing copper-gold-silver polymetallic metallogenic subbelt of the eastern Qinzhou-Hangzhou metallogenic belt.The main outcropping strata is the second submember of the upper section of the Neoproterozoic Zhangcun Formation which can be divided into four types:loose rock group,weak rock group,semi-hard rock group and hard rock group.Based on analysis and summary of the engineering rock group type,structural plane and rock mass quality in the mining area,the engineering geology of the mining area is evaluated,and relevant prevention countermeasures are put forward to the main engineering geological problems such as mined-out area and open-air waste-dump in the mining area,which provides reference for subsequent mining.
