摘要
Abstract
Through geological survey,the authors infer that there are more blind orebodies at the depth of the Lucaotan mining area,and hence it is necessary to carry out further exploration.Using the 1:1 million ground high-precision magnetic measurement,the authors delineated the magnetic anomalies,inferred and divided the geological structures.Through interpretation and study of the magnetic anomalies,the authors found the hidden magnetite orebody.By using the 2.5D human-computer interactive inversion technique the authors inferred that there exist hidden magnetic orebodies at the depth.Borehole magnetic measurement plays an important role in guiding drilling work.Practice has proved that the organic combination of ground magnetic measurement and borehole magnetic measurement in the exploration of the Lucaotan magnetite deposit has made significant prospecting effect.关键词
