摘　　要：备战铁矿地处西天山伊犁地块东北缘活动带中,为中高山区,属高山深切地貌。经近十年开发,矿体浅层规模及形态已基本查明,深部潜力有待进一步挖掘。由于地形切割剧烈,该矿区地面地球物理工作困难。采用小型旋翼无人机及数采组成的航磁测量系统在备战铁矿开展测试与应用,获得关键区域高精度磁异常数据。通过约束模型分析,推测深部分布有隐伏矿体。The Beizhan iron ore is located in the active zone of the northeast edge of the Yili massif in the Western Tien Shan,which is a medium-high mountainous area and belongs to the deep mountainous terrain.After nearly ten years of development,the shallow scale and morphology of the ore body have been basically identified,and the deep potential needs to be further explored.The ground geophysical work in this area is difficult due to the intense topographic cutting.In this paper,an aerial magnetic survey system composed of a small rotary-wing UAV as well as a digital mining was tested and applied in the prepared iron ore mine,and magnetic anomaly data in key areas were obtained.Through model analysis,the distribution of deep hidden ore bodies was inferred.
