摘要
传统勘查方法在地质找矿过程中,对矿产分布情况的勘查准确率不高,为此提出应用海底重力勘查方法进行地质找矿。对地质密度差进行勘查,提取地质构造信息,计算地质矿物的发射率和波谱,从而实现高效精准的地质找矿。通过实验论证可以得出,相比传统方法,应用海底重力勘查的找矿方法能够提高勘查准确率,并且随着地质勘查面积的不断增加,这种优势更为明显。
In the process of geological prospecting,the accuracy of traditional prospecting methods is not high,so the submarine gravity prospecting method is proposed for geological prospecting.The geological density difference is investigated,the geological structure information is extracted,and the emissivity and spectrum of geological minerals are calculated,so as to realize efficient and accurate geological prospecting.Through the experimental demonstration,it can be concluded that compared with the traditional method,the prospecting method of submarine gravity survey can improve the survey accuracy,and with the continuous increase of geological survey area,this advantage is more obvious.
