摘要:

在全国老矿山深部找矿项目实施过程中,根据已获得矿山深部勘查成果,以及系统收集的研究区地质勘查和科学研究成果,发现七里坪F60-I金银矿脉的深部又出现了金品位再次升高的趋势。通过研究已知矿体的空间赋存状态、分布规律与成矿特征,分析中深部构造成矿、控矿特征及成矿元素变化规律,基于MapGIS DTM空间数据分析,采用权值等值线进行了矿体空间延伸趋势预测,系统分析了矿体的三维空间状态。参考已有矿体工程验证效果,调整了矿体空间预测方案与验证工程,并获得了良好的深部预测效果,实现了老矿山深部整装勘查找矿的突破,对研究区中深部找矿工程部署乃至整个小秦岭地区深部找矿具有很好的指导意义和示范效应,有效促进了小秦岭地区深部地质找矿工作的工程部署和勘探验证工程的实施。

Abstract:

According to the obtained results of mine deep exploration,the systematic collection of geological exploration as well as scientific research achievements in the study area,in the process of project implementation for the old mine deep prospecting nationwide,it was found that gold grade of the deep gold-silver vein exhibited a rising trend at the Qiliping F60-I gold and silver orebody.Through study on occurrence of state of the known orebody,regularities of distribution and ore-forming characteristics,deep tectonic mineralization,ore-controlling characteristics and metallogenic elements were analyzed.Additionally,based on MapGIS DTM spatial data analysis,the weight contour was applied for predicting space extending trend of the ore body,moreover,the state of the three-dimensional space of the ore bodies was likewise systematically studied.Reference for ore body engineering validation effect,the orebody spatial prediction scheme and validation project were adjusted and a good prediction effect was obtained.Meanwhile,we achieved the old mine deep ready exploration prospecting breakthrough,which had the very good guidance significance and demonstration effect deep prospecting engineering deployment for the deep prospecting in Xiaoqinling area,and it can effectively promote the deep geological prospecting work of the implementation and exploration engineering in the study area.

Key words: mineralization, ore-controlling structure, deep prediction, DTM spatial analysis, Xiongershan area, Henan Province
