摘　　要：综合物化探方法在我国矿产勘查领域中取得了较好的找矿效果,近年来被广泛应用。本次研究利用航空伽玛能谱测量、地面伽玛能谱测量、音频大地电磁测量相结合的方式,对黑龙江省嘉荫县磨石山滚子沟地区进行铀矿勘查工作。首先通过航空伽玛能谱测量数据,选定重点找矿地区;其次在地表利用地面伽玛能谱测量,探寻了铀矿化异常信息;利用音频大地电磁测量,查明其断裂构造形态特征;最后利用槽探工程,对铀异常线索进行了揭露,形成了一套航空(综合选区)—地面(查明铀异常特征)—地下(探槽揭露)"三位一体"综合找矿方式,并取得了较好的找矿效果。In recent years, the integrated geophysical method in the field of mineral exploration in China has achieved good pros- pecting result, and therefore is widely used. In this case study, the uranium prospecting work in Gunzigou area at Jiayin county, Heilongjiang Province, was used by a combination method of aviation gamma spectrum measurement, ground gamma spectrometry and audio magnetotelluric measurements. First, the key prospecting area was selected by the airborne gamma energy spectrum measurement, then, the uranium mineralization anomaly information was extracted by ground gamma spectrometry, after that the structral morphology was obtained by using audio magnetotelluric measurements. Finally the uranium anomaly was verified by trenching work.Thus, a set of integrated prospecting model was constructed, which consisting of a set of aviation geophysical measurement （ comprehensive selection of target area） - ground method （identify uranium anomaly characteristics） - underground test method （exploratory trenching）, which achieved good prospecting result.
