摘要
位于焦家断裂带的新城金矿床矿体主要赋存于主裂面(断层泥)下盘的黄铁绢英岩化碎裂岩带和黄铁绢英岩化花岗闪长质碎裂岩带内。根据勘探资料和测试数据对矿床内Ⅰ号和Ⅴ号主要矿体的赋存特征进行分析,并结合矿区水文和环境特点对矿床进行了开采评价。研究结果表明,新城金矿区工程地质条件简单;矿床开采形成的采空区对矿区岩体稳定性产生的影响较小,研究区内的主矿体为地质环境条件良好型矿体。
Xincheng gold deposits located in the footwall（ fault gouge） of the Jiaojia fault store consist of pyrite phyllic cataclastic zone and pyrite phyllic granodioritic rock band fragmentation. By analyzing the characteristics of the main ore body-NO. Ⅰ and Ⅴ,evaluating the conditions for mining,the engineering geological condition of deposits is easy,and mined-out area has little influence on the stability of the rock mass in the deposit. Based on the environmental geological conditions of the deposits,it is favorable for mining.
