摘要 甘肃东车路沟金矿床是北祁连成矿带的一部分,其主要为石英脉型金矿,受该地区多期次热液活动影响,该金矿矿体展布形态复杂、品位变化较大、采矿地质条件较差,给深部矿体的预测和探采工程的布设造成很大影响。本文利用分形理论研究了矿区S1主矿体的品位、厚度等分维值在垂向上的变化,并与化探原生晕分析方法相结合,得出S1矿体向深部继续延伸的可能性较大的结论,对于该类型矿床深部找矿工作具有一定的指导作用。 The Dongchelugou gold deposit in Gansu Province is a part of the North Qilian metallogenic belt.It is mainly a quartz vein type gold deposit.Influenced by the multi-stage hydrothermal activities in this area, the distribution of the gold deposit is complex, the grade varies greatly, and the mining geological conditions are poor, which greatly affects the prediction of deep orebodies and the layout of exploration and mining engineering. . In this paper, the fractal theory is used to study the vertical variation of the grade and thickness of S1 main orebody in the mining area. Combined with the method of geochemical primary halo analysis, it is concluded that the S1 orebody is likely to extend further to the depth, which has a certain guiding role for the deep prospecting of this type of ore deposit.
