摘要
通过在矿区内开展激电中梯扫面、激电中梯剖面、联合剖面法、对称四极测深法等综合激电工作,并结合矿区地质特征、地球物理特征,推断矿致异常三个,指明异常中心位置,推断出极化体倾向,解释出极化体顶部埋深。提出了一个物探异常验证孔,经钻探验证见矿,证明了激电工作在石墨矿区的应用效果良好。
Based on analysis of geological features and geophysical characteristics of the graphite mine, three ore-induced anomalies in this area were inferred by means of integrated stimulus methods including electric ladder-sweeping surface, electric ladder section,composite profiling and symmetrical four-pole sounding, indicating the centers of anomalies, inferring polarization tendency, interpreting top buried depth of polarization bodies and showing a verification hole for geophysical anomalies, from which the discovery a graphite occurrence has indicated that application of IP work in graphite mining area has a good effect.
