摘　　要：对于地形切割厉害、环境条件恶劣地区,采用传统勘查方法开展地面查证具有较大困难.结合工程应用实践,充分发挥放射性勘查方法快速分析、对地形要求较低的优势,代替部分传统物化探方法,提出了一种放射性物探方法与传统物探方法相结合的快速查证方法组合.本方法组合分为三个阶段完成地面查证,采用层层递进工作方式,前一阶段为后一阶段工作指明方向.各阶段采用不同的放射性勘查方法和传统物探方法,且勘查方法相互补充,弥补单一勘查方法的不足,完成地面查证工任务.在工程验证阶段,采用浅钻结合X荧光岩芯分析勘查技术,较大的降低了野外工作强度.实践证明,该方法组合是一种快速高效、经济的勘探方法组合,旨在为找矿勘探工作提供一种新的思路.In the area which has great surface rolling and adverse weather, it is difficult to apply the traditional geophysical and geochemical prospecting methods for verification work. Combining with engineering practice, the radioactive prospecting methods have the advantage of rapid analysis and low requirement for terrain. Therefore, the radioactive prospecting methods apply to aeromagnetic anomaly verification instead of some traditional prospecting methods. A fast prospecting methods combination for aeromagnetie anomaly verification has established. The fast prospecting methods combination contain three stages, the verification work must follow a progressive rule. The accomplishment of a stage directs the later stage work. Very stage also contains different prospecting methods, including radioactive prospecting methods and traditional prospecting methods. Different prospecting methods complement each other, and make up single prospecting method, complete ground verification work tasks of each stage. In the stage of engineering verification, shallow drill instead of trial trench is used to decrease cost. The verification work of aeromagnetic anomaly located in West Tianshan Mountains has proved that the radioactiveprospecting method combination is efficient and economic. This prospecting methods combination may provide a new train of thought for mineral exploration.
