摘要
为查明东鞍山铁矿多种类型矿体的空间形态和矿物组分的空间分布情况,指导矿山开展深部找矿工作,基于矿区水平断面与钻孔数据等地质资料,依托3DMine平台,采用三维地质建模和距离幂次反比法分别建立研究区矿体模型和品位分布模型。在三维模型基础上,结合矿床成因和矿体分布规律,基于“相似类比”和“地质异常”两种矿床勘查理论,提取找矿预测要素,开展深部找矿应用,在矿区深部圈定找矿靶区2处,拓宽了东鞍山铁矿深部找矿空间。
In order to find out the spatial morphology characteristics of various types of orebodies and the spatial distribution of mineral components in Donganshan iron deposit and guide the deep exploration work of the mine,this study is based on geological data such as horizontal section and borehole data in the mining area,relying on 3DMine platform,using 3D geological modeling and inverse distance weighting method to establish the physical model of the orebody and grade distribution model respectively in the study area.Based on the exploration pros-pecting theory of“similar analogy”and“geological anomalies”,and combined with the genesis and rich ore de-posit distribution on the basis of 3D model,the research has extracted ore prediction factors and has carried out the deep prospecting applications.To provide work model for accurate prospecting,two prospecting targets were delineated in the deep part of the study area,which has further broadened the direction of deep prospecting in Donganshan iron deposit.
