基于航放航磁数据的两种成矿预测软件应用对比研究

Application Comparison of Different Metallogenic Prediction Software with Airborne Radioactive and Aeromagnetic Data

为了进一步开发利用航放航磁数据,提供铀及多金属矿找矿线索,将自主研发的成矿预测专家系统和引进的俄罗斯半定量预测软件在阿拉善盟中部和乌拉特后旗-包头一带开展铀矿和金矿成矿预测应用效果对比分析。结果表明:基于航放航磁数据开展成矿预测,成矿预测专家系统结果和半定量预测结果基本一致,且在基岩出露地区专家预测结果更为精准、科学。成矿预测专家系统具有自主研发、数据准备简单、操作简便等优点,可有效代替原有半定量预测软件。

In order to further develop airborne radioactive and aeromagnetic data and provide uranium and poly⁃metallic prospecting clues,The independent metallogenic prediction expert system and the semi⁃quantitative prediction software introduced from Russia were used to carry out the metallogenic prediction of uranium and gold deposits in the central Alxa League and the Wulatehouqi⁃Baotou area.The comparing and analyzing the results of the two softwares showed that the metallogenic prediction expert system are basically consistent with the semi⁃quantitative prediction,and the expert prediction results are more accurate and scientific in the area of bedrock outcropping.The metallogenic prediction expert system has the advantages of independent research and development,simple data preparation and easy to operate,and can effectively replace the original semi⁃quantitative prediction software.
