【摘要】 随着找矿工作向深部发展,可控震源地震逐渐成为金属矿勘探的主要方法。为探讨自行研制的PHVS-500型轻便小型可控震源在金属矿地震勘探中的应用效果,配合使用自行研制的地震观测系统,在甘肃金昌铜镍矿区开展了实验研究。通过PHVS-500与美国Minivib T15000型液压震源的实验剖面对比可知,轻便小型可控震源与国外震源产品在对应位置上反映出的4个反射层信息是一致的,表明了PHVS-500型轻便小型可控震源应用于金属矿勘探中是有效的。更多还原

【Abstract】 With the development to deep exploration,controlled vibrator seismic exploration has become the main method of mineral deposit prospecting.In order to study the effect of portable mini PHVS-500 vibrator,developed by Laboratory of Geo-Exploration and Instrumentation of Ministry of Education in Jilin University,we carried out seismic method experiments in Jinchang copper-nickel mine.In this paper,we compared the seismic time profiles of PHVS-500 portable mini vibrator and U.S.Minivib T15000 hydraulic vibrator.The results show that four reflections are consistent at the corresponding position of two sources.It is concluded that portable high frequency vibrator system we developed is effective in metal deposit prospecting.更多还原
