  • 摘要: 深度学习已在矿产勘查领域得到广泛应用,但复杂网络模型普遍计算量较大。为提升智能找矿预测的精准性与效率,针对传统卷积神经网络(CNN)在矿产资源预测中地质特征关联建模不足、复杂深度学习架构数据融合效率低的问题,以新疆蕴都卡拉地区为研究对象,融合地质、航磁、重力、化探数据,提出基于卷积混合器模型(ConvMixer)的智能找矿预测方法,旨在利用简单的架构实现更加准确的区域预测结果。结果表明:ConvMixer可高效完成多源数据空间融合与成矿特征提取,在调整最优参数后,与CNN相比,ConvMixer预测面积占比由21.18 %降至13.82 %,模型准确率达98.3 %,预测区更连续完整;与Transformer相比,ConvMixer单轮预测时间由2 s缩短至1 s,计算效率得到提升。基于该模型圈定2处找矿预测区,均位于核心含矿地层中,且北西向断裂与物化探异常发育,成矿条件优越。ConvMixer兼具高精度与高效率优势,可为海量网格化地质数据下的区域钴矿资源智能找矿预测提供高效可行的技术方案。

     

    Abstract: Deep learning has been widely applied in the field of mineral exploration. However, complex network models generally involve significant computational demands. To enhance the accuracy and efficiency of intelligent mineral exploration predictions, this study addressed the shortcomings of traditional convolutional neural networks (CNNs) in modelling geological feature correlations for mineral resource prediction, as well as the low data fusion efficiency of complex deep learning architectures. Taking the Yundukala Area in Xinjiang as the study area, the study integrated geological, aeromagnetic, gravity, and geochemical data and proposed an intelligent mineral exploration prediction method based on the convolutional mixer (ConvMixer) model, aiming to achieve more accurate regional prediction results using a simpler architecture. Results indicate that ConvMixer can efficiently perform spatial fusion of multi-source data and extraction of mineralization features. After optimizing parameters, compared with that by CNN, the proportion of predicted area covered by ConvMixer decreases from 21.18 % to 13.82 %, with a model accuracy of 98.3 %, and the predicted target areas are more contiguous and complete; compared with that for Transformer, the prediction time per round for ConvMixer is reduced from 2 s to 1 s, improving computational efficiency. Based on this model, two mineral exploration prediction zones are delineated, both located within core mineral-bearing strata and characterized by well-developed NW-trending faults and geophysical anomalies, indicating favorable mineralization conditions. ConvMixer combines the advantages of high accuracy and high efficiency, providing an efficient and feasible technical solution for intelligent cobalt deposit resource exploration prediction in regions with massive amounts of grid-based geological data.
