摘　　要：在四川拉拉铜矿田海林铜矿区的勘查工作中,采用被动源地震方法进行勘查应用试验,将获得的成果与AMT(音频大地电磁)成果进行对比,发现吻合程度较高,并且在深部的分辨率要优于AMT。通过试验证明被动源地震方法可以有效识别出层控型矿床的含矿地层和围岩,为丰富矿产勘查的物探手段提供了有益的应用实例。Passive source reflection seismic method is tested in exploration of Hailin Cu deposit in Lala ore field of Sichuan province.The result is generally comparable with that of ATM method and better for deep resolution.It is an effective geophysical method to distinguish the ore-bearing strata and surrounding rock of the stratabound ore deposit.
