由于传统的冶金地质勘查技术水平不高,导致勘查效率较差、地质勘查效果差,为了提升冶金地质整体勘查效果,研究了遥感测绘技术在冶金地质勘查中的应用。利用遥感测绘技术获取冶金矿区地表数据,结合瞬变电磁法、高密度电法等多物探方法绘制电阻率切片图以及地质层位发育情况图等,获取冶金地质信息,实现冶金地质勘查。应用结果表明,基于遥感测绘技术的勘查结果与实测钻探结果基本一致,证明利用遥感测绘技术所得地质勘探结果具有精准性、有效性,地质勘查效果好。根据冶金地质勘查信息提取冶金地质矿区内部构造及特征,获取冶金矿石品位等级变化规律,能够为冶金地质勘查工作的开展提供指导。

Due to the low level of traditional metallurgical geological exploration technology,the exploration efficiency is poor and the geological exploration effect is poor.Therefore,in order to improve the overall exploration effect of metallurgical geology,the application of remote sensing surveying and mapping technology in metallurgical geological exploration was studied.Using remote sensing surveying and mapping technology to obtain surface data of metallurgical mining area,and combining transient electromagnetic method,high-density electrical method and other geophysical methods to draw resistivity slice map and geological horizon development map,etc.to obtain metallurgical geological information and realize metallurgical geological exploration.The application results show that the exploration results based on remote sensing surveying and mapping technology are basically consistent with the actual drilling results,which proves that the geological exploration results obtained by using remote sensing surveying and mapping technology are accurate,effective and have good geological exploration results.According to the metallurgical geological exploration information,the internal structure and characteristics of the metallurgical geological mining area are extracted,and the change rules of metallurgical ore grade grade are obtained,which can provide certain guidance for the development of metallurgical geological exploration.
